Revision as of 06:54, 8 November 2022

This page is designed to allow for a quick look over all the drivers with a MACHINE_IMPERFECT_GRAPHICS, MACHINE_IMPERFECT_COLORS or MACHINE_WRONG_COLORS flag by giving, as much as possible, an idea on the amount of effort needed to fix them.


20pacgal

Starfield is not 100% accurate.

2mindril

Video emulation (Taito F3) isn't perfect yet.

3x3puzzl

casanova - Some GFX glitches. Are palette / tilemaps buffered?

40love

40love and clone - Possible bad ROM. Sprite memory needs to be buffered? Pixel layer needs priority?

4roses

GFX and color decode routines need to be fixed.

8080bw

ballbomb - Missing clouds due to incomplete dump.

galxwars and clones, laser, spacerng, spcewarla, spclaser, spcwarl - Missing color PROMs dumps, using the wrong ones for the time being.

invadernc - Color PROM isn't correctly hooked up. It may be a bad dump.

rollingc - Colors don't match available references.

schaser, schasercv - Color PROM was hooked-up, but colors are still marked as imperfect.

sflush - Maybe missing a color PROM dump.

acefruit

sidewndr -

spellbnd -

advision

aeroboto

Starfield emulation is guessed and likely incorrect.

aerofgt

aleck64

doncdoon, hipai, hipai2, kurufev, mayjin3, mtetrisc, srmvs, starsldr, twrshaft, vivdolls - N64 video emulation is lacking some features.

alg

Probably only missing laserdisc dumps.

altos2

CRT9007 emulation is lacking some features.

amaticmg

Graphics are decoded but only 2 bitplanes are hooked up. Colour decoding routines need figuring out.

amiga

amusco

The palette is totally wrong.

anes

Blitter is completely unemulated, so nothing is shown on screen.

argus

Driver has accurate description of the video emulation's inaccuracies.

aristmk4

gunnrose - The color PROM needs to be dumped.

aristmk5

asterix

Problems with the Konami logo: in the original the outline is drawn, then there's a slight delay of 1 or 2 seconds, then it fills from the top to the bottom with the colour, including the word "Konami".

astinvad

spaceint - Wrong colors.

spaceintj - Color PROM is marked as bad dump (same PROM as spaceint).

Video implementation is not complete yet and some ROMs aren't present.

attache

aussiebyte

bagman

sbagmani - Different PROMs, need correct decoding.

banprestoms

GFX emulation should be double checked for glitches once the games are fully playable.

barata

Whack-a-mole type game with no screen. Needs photographic artwork.

basf7100

Real character ROM needs to be dumped and video emulation isn't complete.

battlera

Priorities aren't 100 correct. Only necessary features of the PC-Engine video hardware are implemented: not all PC-Engine video features are used by games in this driver.

battlex

battlex - Missing starfield. Background tile colors are wrong.

dodgeman - BG tilemap palette bits (in most cases paltte 0 is used, only highlights ( battlex logo, hiscore table) uses different palettes(?). Current implementation gives different highlight colors than on real hardware (i.e. battlex logo should have yellow highights).

bbc

GFX emulation isn't accurate yet.

beaminv

ctainv - The game is supposedly colour, but what it puts in RAM seems to be black and white only.

cidelsa

draco - Colors aren't perfect yet.

cinemat

qb3 - Some graphics problems.

circus

crasha - The playfield should be cyan. The entire centre box (and contents) should be pale green.

cischeat

bigrun is the only set which seems to have correct GFX emulation. For the other sets, some ROMs aren't used (priorities?). Screen control register hasn't been found yet (priorities, layers enabling etc.) In f1gpstar, it's unsure whether they are correct in a few places (e.g. in the attract mode, where cars move horizontally, the wheels don't follow for this reason, probably).

cit220

Preliminary driver. Missing GFX modes.

clickstart

Preliminary driver.

clshroad

firebatl - Transparency for the text layer is not correctly emulated.

cninja

cninjabl2 - Bootleg on different hardware. Tilemap offsets need adjusting.

cobra

Missing features / effects.

coinmvga

Driver is still in preliminary status.

cubo

AGA emulation is missing some features.

cybertnk

Sprite zooming and sprite shadows need improving.

dai3wksi

dai3wksi, runaways, warp1, warp1t - Colors generation isn't understood. On the PCB there are no PROMs, so it's hardcoded logic somehow? It's 3bpp colors, not b&w + color overlay.

dassault

Blending effects aren't fully emulated.

dblcrown

There's a bogus "Hole" in main screen display; is the background pen really black?; video / irq timings need work.

dbz

The Banpresto logo in DBZ has bad colors after 1 run of the attract mode because it's associated to the wrong logical tilemap and the same happens in DBZ2 test mode. It should be a bug in K056832 emulation.

dc_atomiswave

Graphics system emulation is lacking some features.

dday

The driver currently hacks a handgenerated color tables, which matches the screenshot. Needs correct emulation.

ddayjlc

Priorities aren't perfect.

dec0

automat, ffantasybl, mastbond, secretab - Bootleg on different hardware.

deco32

dragngun and clones, tattass and clones - Tattoo Assassins & Dragongun use an unemulated chip (Ace/Jack) for special blending effects. It's exact effect is unclear.

lockload and clones - Marked as imperfect graphics.

nslasher and clones - Marked as imperfect graphics.

decocass

cmanhat -

deco_mlc

Blending, raster effect features aren't fully emulated currently.

deniam

logicpro - Logic Pro has an unemulated graphical effect: when you insert a coin, the screen becomes very slightly darker until the next 'scene change'. This is not emulated yet.

deshoros

The display controller isn't identified and the character ROM isn't dumped. Once done, then needs emulating the graphics with genuine artwork display.

dfruit

TC0091LVC emulation lacks some features, resulting in gfx glitches.

dkong

pestplce - Colors and origin unknown.

dmndrby

There are some remaining graphics issues and colors are imperfect.

rad_sinv - Various glitches. See top of the driver.

electron

Graphics seem to be wrong for several games.

eolith

candy VRAM erasing doesn't work properly in this game with the logic used in eolith_vram_w. There are various screens, such as the how to play screen and high score screen where you can see graphics which should have been erased. It has been verified that these get erased correctly on the real hardware.

ep64

equites

gekisou - Various small graphics glitches. More infos on top of the driver.

hvoltage, splndrbt and clones - the interpretation of the scaling PROMs might be wrong. The sprite x scaling is not used at all because it couldn't be figured out. Sprite y scaling is slightly wrong and leaves gaps in tall objects. Note that sprites are 30x30 instead of 32x32.

ertictac

poizone - Video timings are off, causing various glitches.

esh

ettrivia

strvmstr - Color PROMs dumps are bad.

exerion

Screen modulation (before time out) is not emulated.

fcrash

fcrash, ffightbl, ffightbla - GFX glitches during the second cycle of attract mode.

kodb - This bootleg has various graphical issues, mainly with old info not being cleared away. Also, when you are hit, you should flash, but you go invisible instead.

ffightblb, sf2m1, sf2m9, sgyxz, wofabl, wofr1bl - Bootlegs on different hardware suffer from GFX glitches.

raiga, stratof - It's unclear how lower priority sprites are affected by blended sprites.

galastrm

FLIPX support in taitoic.cpp is not quite correct.

galaxia

Colors aren't right(there's no color prom?!). Stars background should be multi color. Bullets need to be improved and astrowar needs accurate sprite/bg sync.

galaxian

aracnis - Marked as imperfect graphics.

bagmanmc, bagmanm2, kong, luctoday, mandinka, porter, superbon, supergx, timefgtr - Missing color PROM dump.

bmxstunts - Needs 1l GFX ROM redump. Colors could be wrong, reference material is needed.

catacomb - Color PROM might be mismatched.

galaxianbl3 - Bad PROM or decode.

galkamika - One GFX ROM is bad.

guttangt - At least one GFX ROM is bad, color PROM wasn't dumped so using the standard one, which might not be correct for this set.

jungsub - One GFX ROM is bad. Some unknown writes, probably GFX related.

ckongmc2, all mandinga sets, pacmanblc, scobrag, scobraggi, takeoff - PROM is dumped but isn't correctly hooked up yet.

olibug - One of the GFX ROMs is bad. Uses the Galaxian PROM, which gives bad colors(?).

portera - Might actually be correct, but no video reference to check.

spactrai -

streakng and clone - Marked as imperfect colors. PROM is dumped.

galaxold

bullsdrtg - One of the GFX ROMs is bad.

dkongjrm - Probably mismatched color PROM.

spcwarp - Missing color PROM dump.

galgames

galgame4 - There are some garbled graphics in two games (Star Tiger and Battle Checkers).

"Radar" is probably wrong.

gstream

x2222o - The available GFX ROMs aren't correct for the older prototype program ROMs.

gsword

josvolly - Video hardware isn't completely understood.

gticlub

Not all features of the Konami 3D hardware have been implemented.

gumbo

homedata

battlcry and clones - Some tiny gfx glitches.

hourouki - In attract mode, it draws a horizontal black bar on the bottom right side of the display.

Needs better emulation of gfx bank switching.

hprot1

ibmpcjr

igspoker

igs_ncs2 - Incomplete dump.

imolagp

Current color implementation is incorrect.

indy_indigo2

indy_4610, indy_4613, indy_5015 -

inufuku

3on3dunk - Tilemap priority is wrong in places (basketball before explosion in attract, highscores).

itech32

drivedge - Uses modified video hardware. It's emulation is quite complete, but still not 100%.

jack

tripool, tripoola - Palette problems during attract mode. The tripool driver used to have a hack making the vblank interrupt go off twice per frame, this made the game run way too fast, but no palette bug.

jaguar

jalmah

Back layer pens look ugly in some circumstances (i.e. suchipi when you win, mjzoomin when coined up).

jchan

There are some priority issues.

jclub2

darkhors - Needs fixing of the disalignment between sprites and tilemap (gap in the fence) during play, without breaking the other screens, which are fine.

jclub2 and clones - Priorities need some work.

jongkyo

Colors are wrong, possibly due to wrong video RAM banking.

jpmimpct

cluedo and clones - During the attract mode, just after the camera flash, the camera colours go screwy and proceeding text is printed behind the camera. A TMS34010 emulation flaw or original game code bug.

jtc

jtces40 - Hi-res GFX and colours need fixing.

kaneko16

packbang - Priorities between stages could be wrong.

kingdrby

Work needed on remaining video issues, priorities, sprites, etc. Tilemap color offsets aren't understood.

koftball

Game marked as imperfect graphics. No further note in the driver.

koikoi

Colors are incorrect (color(?) prom outputs are connected to one of pals). It might help to have a screenshot of the original thing.

konamigs

Q2SD GPU emulation is preliminary and only implements the features needed by the only game dumped.

konamigx

All games have minor graphics glitches.

ggreats2, opengolf, opengolf2, racinfrc, racinfrcu - Need ROZ layer emulation.

vsnetscr and clones - Need adding of 'Roz Doubling' support to the Type-4 roz rendering when width > 512 and fixing of the issues with FG Tilemaps (the hack used for Soccer Superstars clearly doesn't work here causing most of the left screen tilemaps to vanish).

winspike and clones - Bad sprite colours (might be more protection).

konamim2

btltryst - Unemulated GFX modes make the game too glitchy to be playable.

heatof11 -

konmedal

buttobi, ddboy and clone - Priorities not understood and wrong in places, apparently controlled by PROM.

konmedal68k

Some small gfx glitches remain.

kyugo

99lstwarb - BG tilemap is wrong in some levels. PROMs weren't dumped for this set, so a dump is needed.

There are weird palette changes and some video reference would be useful to verify GFX emulation in general.

lbeach

Colors aren't probably 100% correct yet. No reference available.

lethal

'External' rowscroll not hooked up correctly (1st attract level, highscores). There possibly are some priority issues / sprite placement issues.

lethalj

franticf and clone - Flickers when inserting a coin.

lft_craft

lft_phasor

PAL emulation is missing.

liberate

prosport, prosporta - Marked as imperfect graphics. No further note in the driver.

littlerb

The VDP device isn't perfectly understood yet.

lkage

bygone - Title screen glitches, other glitches.

lordgun

lordgun - In the 3rd leg of the ship stage, sometimes part of a far jetboat is drawn above a nearer sub (both sprites). But this is correct considering both priorities and sprite list positions. Original game bug? Wrong colors for tilemap 0 in the 2nd leg of the last stage (where some sprite priority bugs happen too). In the jungle level, final enemy, tilemap 0 does not scroll. It may have wrong priority, or may need to be disabled, even though it is used by enemies to hide, so it's probably just odd but right after all.

lsasquad

Wrong sprite/tilemap priority. Scrollram not entirely understood.

m10

Colors are close to screenshots for IPM Invader. The other games have not been verified.

m107

wpksoc and clone - Graphics glitches due to some unimplemented features.

m62_bkungfu

Blitter data is encrypted and MCU is undumped.

ppan - Bootleg on different hardware.

magicfly

bchance - One of the GFX ROMs is a bad dump.

malzak

invasnab and clones, mk4 and clones - Zeus chip emulation is incomplete.

crusnexo and clones, thegrid and clones - Zeus 2 chip emulation is preliminary.

minicom

mitchell

mstworld - Bootleg with different video RAM banking.

mstworld2 - GFX garbage at title screen with clean NVRAM. Might be a BTANB.

mjkjidai

mjkjidai - Several imperfections with sprites rendering:some sprites are misplaced by 1pixel vertically and during the tile distribution at the beginning of a match, there's something wrong with the stacks moved around, they are misaligned and something is missing.

model1

swa and clone - Ship models periodically disappear for a frame or two during attract mode and while in-game.

vformula - TGP coprocessor emulation is incomplete.

model2

Video hardware emulation is lacking many features.

monon_color

Some unimplemented GFX features.

monzagp

Incorrect colors and some GFX inaccuracies.

moo

bucky and clones - GFX glitches.

moomesa and clones - Needs 54338 color blender support(intro gfx missing and fog blocking view). Enemies coming out of the jail cells in the last stage have wrong priority. Could be tile priority or the typical "small Z, big pri" sprite masking trick currently not supported by K053247_sprites_draw().

mpu4mod2sw

connect4 - Uses incandescent lamps to make a display grid, need better timing to make this work

mpu4vid

mquake

Marked as imperfect graphics. No further note in the driver.

ms32

mz2500

n64

n8080

helifire, helifirea

namcofl

Graphics system emulation is lacking some features and some aren't understood.

namcos22

Graphics system emulation is lacking some features and some aren't understood.

namcos23

Graphics system emulation is lacking some features and some aren't understood.

namcos86

wndrmomo - Enemies coming out from the ground cut "holes" from the crowd in the foreground. This is because the crowd sprites have higher priority, but come earlier in the sprite list, so now that sprite/tilemap orthogonality is implemented, crowd is obscured by sprites following it, which are obscured by the tilemap. Reverting to the previous behaviour, removing orthogonality, would fix the problem, but It's almost sure it wouldn't be correct.

naomi

Graphics system emulation is lacking some features.

nbmj8900

ohpaipee -

neoprint

Needs implementation of the remaining video features. Needs simulation of the printer/camera devices, lamps.

nes

PPU emulation needs to be brought up to par with current knowledge.

nes_m8

PPU emulation needs to be brought up to par with current knowledge.

nes_m82

PPU emulation needs to be brought up to par with current knowledge.

nes_vt02_vt03

These NES clones have modified hardware. Differences aren't fully implemented yet, causing imperfect graphics and/or colors in these games.

nes_vt09

These NES clones have modified hardware. Differences aren't fully implemented yet, causing imperfect graphics and/or colors in these games.

nes_vt32

These NES clones have modified hardware. Differences aren't fully implemented yet, causing imperfect graphics and/or colors in these games.

nes_vt369_vtunknown

These NES clones have modified hardware. Differences aren't fully implemented yet, causing imperfect graphics and/or colors in these games.

news_r4k.cpp

Framebuffer isn't emulated.

nightgal

ngalsumr, ngtbunny, nightgal, royalngt, royalqn, sgaltrop - Blitter isn't fully implemented yet. Charles MacDonald wrote technical notes about it. There's also a protection device.

nmk16

spec2k - The ships sometimes scroll off the screen if you insert a coin during the attract demo.

nwk-tr

Complex Konami 3D hardware. Some features aren't correctly implemented yet.

nycaptor

Driver needs real bg/sprite priority system.

oneshot

oneshot - Priorities for some tiles are wrong. There might be a layer order register.

othello

Correct colors need to be derived from the color DAC (24 resistors) on PCB.

overdriv

Lots of problems: Missing road (two K053250). Visible area and relative placement of sprites and tiles are most likely wrong. Some flickering sprites, this might be an interrupt/timing issue. The screen is cluttered with sprites which aren't supposed to be visible, increasing the coordinate mask in K053247_sprites_draw() from 0x3ff to 0xfff fixes this but breaks other games (e.g. Vendetta). The "Continue?" sprites are not visible until you press start. Priorities need figuring out.

pacman

cannonbp - Color PROMs should be correct but give wrong ugly colors.

eggor - Color PROMs might be mismatched.

mspacmanbco - This PCB has swapped Blue and Green color lines (Ms.Pac-Man sprite should be pink).

painter - Sprite ROM dump is bad.

panicr

Sprite - sprite priorities are possibly wrong. Needs video reference.

paradise

paradlx, para2dx - Marked as imperfect graphics with no further note. Perhaps the flag wasn't removed after adding correctr gfx3 ROMs?

phoenix

capitol, cityatta, pleiadbl, pleiadce, pleiads, pleiadsi, pleiadsn - Palette banking. Controlled by 3 custom chips marked T-X, T-Y and T-Z. These chips are responsible for the protection as well.

phoenixi - This bootleg uses 1 8-bit PROM instead of 2 4-bit ones like the vast majority of the other games on phoenix hardware. Needs correct decoding.

pingpong

cashquiz - Incomplete dump.

pinkiri8

Current blocker is the video emulation i/o ports, it looks somewhat exotic. Colors are wrong.

piratesh

The KONAMI custom GFX chips' emulation isn't perfect yet.

pktgaldx

pktgaldxb - There are GFX glitches in background of girls after each level.

playch10

pc_bstar, pc_miket, pc_pinbt - GFX glitches due to mapper or PPU problems.

pc_cshwk - Severe GFX glitches on the second level.

pc_ebike - Scanline in middle of screen scrolls when it should not.

pc_ngai2 - Level 2 BG graphics are a total mess.

pc_radr2, pc_radrc, pc_sjetm -

playmark

luckboomh - Lucky Boom has some minor colour issue with the background - see the title screen. The game selects the wrong colour for some tiles. The tiles should be colour 0x01 not 0x02. Affects the backgrounds in game however it's barely noticable.

plus4

plygonet

Player's tank currently flickers on and off during the first in-game attract-mode segment.

pofo

Cursor is missing. LCD board isn't emulated.

polepos

grally, polepos2bi, polepos2bs - Bootleg on different hardware. Colors aren't correctly decoded yet.

popobear

Auto-animation speed is erratic (way too fast).

portrait

Some sprite issues and palette system isn't understood.

powerbal

atombjt - Game adapted to this hw, might still have some GFX glitches lurking.

progolf

Map display is (almost) correct but color pens aren't.

psion

psion5

pturn

Palette decoding isn't perfect.

pve500

quasar

Marked as imperfect graphics with no further note.

quickpick5

quickp5 - Some small gfx glitches remain.

quizpun2

rabbit

Missing raster effects (see left side of one of the levels). Needs clean up of the zoom code and a more accurate zoom effect.

rainbow

realbrk

Need priority handling (e.g during the intro, there are two black bands in the background that should obscure sprites). Sometimes sprites are shrinked to end up overlapping the background image in the tilemaps, but they are a few pixels off.

redalert

demoneye - Missing the 3rd GFX layer.

rltennis

Various gfx glitches here and there, mostly related to wrong size of data.

rohga

Wrong/unemulated alpha/priority functions.

ron

Palette PROMs not correctly hooked up.

roul

Palette and blitter command 0x00 need verifying.

route16

jongpute, vscompmj - Palette decoding is wrong.

royalmah

chalgirl - Missing PROM dump.

ichiban, pongboo2 - Palette handling is wrong (games don't work anyway).

mjsenka, mjyarou and clone, rkjanoh2 - They never seem to set the palette base.

mjsiyoub - Colors need verifying.

rungun

Missing dual monitor support. Sprite palettes are not entirely right. ROZ update causes music to stutter.

saitek_intchess

Colors are estimated from photos (black and white are obvious, but the green and cyan are not standard 0x00ff00 / 0x00ffff), video timing is unknown, sprite offsets are estimated from photos.

sangho

pzlestar - Title screen uses sprites with screen 12, has wrong colors due of it.

sbrain

Missing row buffering DMA (DP8350, MM5035) and line-by-line rendering and proper character generator emulation (CRT8002).

sbugger

sbugger, sbuggera - Wrong colors: it looks like there's direct color mapping. Bits from attribute RAM connected to r/g/b outputs without use of color prom or color table.

scobra

tazmaniet - PROMs are dumped but not correctly hooked up.

scramble

troopy - Bad GFX ROMs.

scregg

rockduck - Color PROMs are mismatched.

scyclone

Colors need to be verified.

sderby

croupierb, magictch - Wrong text layer hook up, some scroll offsets are wrong.

seabattl

Colors aren't correct(note: the flyer screenshots look faked; not a good reference). It's unknown if it should have a horizon/sky. Video timing and video offsets aren't correctly implemented.

segaatom

Preliminary driver. H8S/2373 based.

segajw

Preliminary driver.

segas16a

fantzonepr - Bad / missing GFX ROMs.

segas18_astormbl

There are glitches that need to be verified against hardware.

segas24

Missing linescroll in special modes (qgh title, mahmajn2/qrouka attract mode) and screen flipping (mix register 13 & 2).

crkdown and clones - Clipping / solid layer problems? (Radar display).

qsww - Wrong background color on title screen.

sgmastc and clones - Some gfx offset / color problems?

segas32

Some graphics effects aren't understood / implemented yet.

segasp

Graphics system emulation is lacking some features.

seibuspi

Missing alpha blending effect: screenshot on www.system16.com show that during attract mode in Viper Phase 1 the "Viper" part of the logo (the red part) should be partially transparent. Same thing with the blu "Viper" logo when on the "push 1 or 2 players button" screen. Note that the red logo is tiles, the blue logo is sprites. Same thing with the lights on the ground at the beginning of the game. They are opaque now, you should see the background tiles through.

sengokmj

Some video C.R.T. registers aren't understood. Some sprites bugs at the start of a play.

seta

blandia and clones - There is at least a missing rowscroll effect.

crazyfgt - Graphics glitches.

extdwnhl - Has some wrong colored tiles in one of the attract mode images and in later tracks.

superbar, wiggie - There are a few gfx emulation bugs (flipping of some border tiles and sprites not leaving the screen correctly). It's possible the custom hardware doesn't behave *exactly* the same as the original seta hardware.

seta2

deerhunt and clones, wschamp and clones - Offset tilemap sprite during demo.

grdians and clones - The map screen after the character selection needs zooming. There is a global zoom register that should affect the background map and the level picture but not the frontmost frame. This latter should use color 7ff (the last one) and ignore the individual color codes in the tiles data. Zooming is also used briefly in pengbros.

myangel - Some gfx at the end of the game (rays just before fireworks, and the border during the wedding) have wrong colors. You can see the rays red, green and yellow because that's how the palette is preinitialized by MAME, but the game never sets up those palette entries. The game selects color depth "1", whose meaning is uncertain, and color code 0 so there doesn't seem to be a way to point to a different section of palette RAM. There are glitches in the bg horizontal scroll in the wedding sequence at the end of the game. It looks like "scrollx" should be delayed one frame wrt "xoffs".

myangel2 - Before each level, the background image is shown with completely wrong colors. It corrects itself when the level starts.

endrichs and clones, reelquak - Needs an x offset for tilemap sprites. There are one frame glitches in the reels scroll.

staraudi - Needs flipscreen hook up.

telpacfl - One of the GFX ROMs is a bad dump.

trophyh and clone - MAME hangs for around 15 seconds every now and then, at scene changes. This is probably due to a couple of frames with an odd or corrupt sprites list, taking a long time to render.

turkhunt -

shangha3

Zoom support isn't accurate, possibly other missing blitter features.

shanghai

blocken - Incomplete zoom support, and missing rotation support. Setting the game in Game Mode B shows a decent test case for it by starting a play.

kothello - Small GFX glitches.

shanghai - The end of round animation in Shanghai is wrong.

sis630

Preliminary driver. Big TODO on top of file.

sidearms

sidearms and clones - Starfield emulation is preliminary.

simple_st0016

koikois, mayjinsn - Marked as imperfect graphics, no further note.

skimaxx

The player often disappears (when she's too slow?). Is this normal ?

skylncr

bdream97, seadevil - GFX glitches.

olymp, score5, sonikfig, spcliner - Palette not understood. The games don't ever seem to get to using the ramdac, even though disassemblies show the routines are there.

smc777

snes

Snes video emulation isn't perfect yet.

snesb

Snes video emulation isn't perfect yet.

spacefb

Bullet colors are incorrect.

spaceg

Various gfx glitches.

spbactn

Sprite / tile priority is sometimes wrong (see 1st table when ball in bumpers). Some of the code which is from the other drivers such as sprite drawing needs verifying, as priorities are questionable in places. Needs support for blended sprites.

spcforce

Color decoding isn't fully understood.

special_gambl

The pens are borrowed from Specialist MX and probably wrong.

speglsht

Some GFX glitches.

Graphics aren't fully understood yet.

ssingles

Colors are wrong (possibly missing PROMs).

ssrj

Wrong colors (possibly missing PROMs). Video hardware isn't fully understood.

ssv

All games are missing CRT controller emulation (resolution+visible area+flip screen?).

dynagear - Visible area may be incorrect.

eaglshot -

janjans1 -

janjans2 -

pastelis - Imperfect raster effects in ending credits and shadows.

stmblade and clones - There is a rogue "tilemap" sprite that pops up at level 2 and stays there till the end of the game (a piece of sky to the left of the screen). It seems that the x&y offsets in the sprite list should be applied to it (-$200,-$200) to move it off screen. But currently those offsets are ignored for "tilemap" sprites. This may be related to the kludge for srmp4 and to the kludge for keithlcy.

ultrax and clones - Backgrounds are offset by $10 pixels, so they're kludged to work.

stuntair

Needs correct colour PROM decoding (resistor values?), correct FG colour handling (currently use a hardcoded white) and fixing remaining GFX / sprite issues (flicker sometimes, might need better vblank timing?).

stv

Video emulation is lacking some features / the video system isn't completely understood. Detailed list of problems in the driver.

subsino2

qbeebing, queenbee and clones, squeenb, treamary - Empty reels when bonus image should scroll in via L0 scroll. The image (crown/fruits) is at y > 0x100 in the tilemap.

ptrain - Missing scroll in race screens.

summit

Scrolling is wrong, missing graphics at top and right (pound values), palette (currently handmade).

suna8

sranger and clones - Various imperfections (see fireball masking, lev. 5; masking/missing legs, lev. 10).

starfigh - Missing starfield effect.

superwng

Missing color PROM dump.

supracan

Some weird framebuffer vertical gaps with some object, namely the green and the trees (zooming?).

suprnova

Video emulation is missing many features. Detailed list in the driver.

suprslam

Sprite offset control hasn't been found.

system1

gardiab, gardiaj - Some graphics glitches.

system16

Bootlegs on different hardware. Most supported sets need proper video hardware implementation.

tabe22

Probably missing some text effects.

taitoair

topland and clones - Framebuffer DMA requires palette switch to be selected dynamically, see at first stage Course Select in Top Landing. Night stages might have wrong priority for stars-above-sea.

taitojc

3D graphics system isn't fully implemented.

taitopjc

Some GFX glitches remain.

taito_b

hitice and clones - Ice trails are incorrect. The pixel bitmap is not cleared on startup nor during attract mode. There's a kludge to fix it in the first case.

taito_f3

commandw - Some clipping and layer problems.

quizhuhu - Quiz text positioning, heavy sprite window usage.

taito_l

plgirls2b - Scroll offset problems.

taito_z

tmc1800

nano -

tmmjprd

In 16x16 tile mode, the offset into tileram doesn't necessarily align to 16x16 tiles! This makes using the tilemap system excessively difficult, as it expects predecoded tiles which simply isn't possible here. This is used for the girls in the intro at least, they specify 16x16 tiles on non 16x16 boundaries. (basically the physical tile ROM addressing doesn't change between modes even if the data type does).Video has a 'blitter' but it isn't used by these games, it is used by Rabbit. Sprites from one screen are overlapping on the other, probably there's a way to limit them to a single screen. Priorities are wrong.

tmpdoki - Possible bad dump.

tmnt

glfgreat and clones - They have some problems with the zooming sprites and playfield graphics.

ssriders and clones - Marked as imperfect graphics. No further note in the driver.

ssridersb - Bad dump.

tnzs

jpoponics - Palette format (or gfx decode?) appears to be incorrect, some colours clearly don't match the screenshot. The bar behind the players flickers first during boot / first attract levels. Is might be a bug.

trackfld

mastkin - Color PROMs aren't dumped.

trvmadns

dquizgo - Layer offsets need checking.

funkyjetb - Wrong palette.

semibase - Some sprite offsets problems.

tutankhm

Missing starfield emulation.

tv955

Video emulation is lacking some features.

twins

spider - Blitter / clear logic may be improved.

undrfire

Sprites on some rounds had sprite/tile priority issues. Solved by upping sprite priority while TC0480SCP row zoom is enabled - kludge.

unichamp

unior

Color PROM isn't dumped.

The blitter isn't understood / correctly emulated. Lots of glitches / missing effects, as listed at the top of the driver.

williams

mysticm and clone - Palette decoding isn't fully understood.

wiz
