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

aristmk4

gunnrose - The color PROM needs to be dumped.

aristmk5

sbagmani - Different PROMs, need correct decoding.

barata

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

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).

cybertnk

Sprite zooming and sprite shadows need improving.

dai3wksi

The BG colour calculation is not understood.

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.

dday

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

ddayjlc

decocass

csdtenis -

deco_mlc

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

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.

It has been verified that these get erased correctly on the real hardware.

ep64

epos

igmo - Missing color PROM dump.

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.

poizone - Video timings are off, causing various glitches.

esh

ettrivia

strvmstr - Color PROMs dumps are bad.

exerion

zipzap - Bad dump.

famibox

Screen modulation (before time out) is not emulated.

fcombat

Needs fixing of the colors (sprites, background).

fcrash

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.

galaga

bosco and clones - The starfield is wrong.

galastrm

FLIPX support in taitoic.cpp is not quite correct.

Current color implementation is incorrect.

indy_indigo2

indy_4610, indy_4613 -

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.

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, winspikej - Bad sprite colours (might be more protection).

konamim2

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

heatof11 -

konmedal68k

Some small gfx glitches remain.

kyugo

99lstwarb - BG tilemap is wrong in some levels.

laserbas

There are weird palette changes and missing bg scrolling between stages.

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.

crusnexo, crusnexoa, crusnexob, thegrid, thegrida - Zeus 2 chip emulation is preliminary.

minicom

mitchell

mstworld - Bootleg with different video RAM banking.

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

vf, vformula - TGP coprocessor emulation is incomplete.

model2

model 2, model 2A, model 2B games - 3D coprocessors emulation / hook-up are incomplete.

Video hardware emulation is lacking many 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().

mpu4dealem

dealem - occasional black tiles seem odd compared to video (http://youtube.com/watch?v=p0bJYxaCBao).

mpu4mod2sw

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

mquake

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

ms32

Video system is only partially understood. Extensive TODO on top of the driver.

murogem

The palette system needs to be understood.

mystwarr

All games are marked as imperfect graphics. No further note in the driver.

mz2500

n64

n8080

helifire, helifirea

namcofl

finallap and clones - Sprite size bit is bogus during splash screen. Bad road colors.

finalap2, finalap2j, suzuka8h, suzuka8hj, suzuka8h2 - Bad road colors.

finalap3, finalap3j - Use unaligned 32x32 sprites, which aren't handled correctly in video/namcos2.cpp yet. Bad road colors.

fourtrax and clones -

namcos21_c67

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

namcos21_de

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

nes_vt

They use modified PPUs which features aren't completely emulated yet.

Palette decoding is wrong.

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 have swapped Blue and Green color lines (Ms.Pac-Man sprite should be pink).

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?

pasopia7

pc1512

peplus

pebe0014a, pemg0213, pepp0045b, pepp0045c, pepp0130, pepp0733, peps0615, peps0628, pex0057pb, pex0057pd, pex0827s, pex0846s, pex1087s, pex2172pa, pexm009p - Wrong CG graphics and/or CAP ROMs.

phoenix

capitol, pleiadbl, pleiadce, pleiads, pleiadsi - 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_1942, pc_bstar, pc_gntlt, pc_miket, pc_pinbt - GFX glitches due to mapper or PPU problems.

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

pofo

Cursor is missing. LCD board isn't emulated.

polepos

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

Marked as imperfect graphics with no further note.

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.

redclash

Colors are unverified (some screenshots are needed). Some graphical problems.

rltennis

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

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 - Maybe imperfect GFX decode or maybe bad GFX ROMs.

scregg

segajw

Preliminary driver.

segas16a

fantzonepr - Bad / missing GFX ROMs.

segas24

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

crkdown, crkdownj, crkdownu - Clipping / solid layer problems? (Radar display).

qsww - Wrong background color on title screen.

sgmastc, sgmastj - Some gfx offset / color problems?

segas32

Some graphics effects aren't understood / implemented yet.

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, blandiap - 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 clone - Offset tilemap sprite during demo.

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

staraudi -

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

trophyh - 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

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.

sidearms

sidearms, sidearmsj, sidearmsr - 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 - GFX glitches.

sonikfig - Palette not understood.

skyraid

Color decoding isn't fully understood.

sliver

Some transparency problems in some stages.

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.

speglsht

Some GFX glitches.

spg110

Preliminary driver. Sunplus SPG110 based.

spoker

3super8 - Roms are badly dumped.

sprint2

Snes video emulation isn't perfect yet.

srmp5

Custom seta video chip emulation is incomplete.

srmp6

Custom seta video chip emulation is incomplete.

sshot

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 - 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 - 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

humlan, squeenb - 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

pushover -

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

suprgolf

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.

taitoair

topland - 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.

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.

taito_l

plgirls2b - Scroll offset problems.

taito_z

Video hardware needs a lot of work. Detailed list of problems in the driver.

tatsumi

Video hardware is extremely complex. Detailed list of problems on top of driver.

tattack

Palette system isn't understood.

taxidriv

Palette system isn't understood.

tecmosys

Some graphic features (linescroll, mixing) aer not perfectly emulated.

tecnbras

tetrisp2

rocknms -

thepit

dockmanc, rtriv - One ROM is badly dumped.

thomson

thoop2

Title screen priority bug.

ti630

tmc1800

tmmjprd

In 16x16 tile mode, the offset into tileram doesn't neccessarily 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, glfgreatj - 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.
