jangou

luckygrl - Encrypted program roms. Might also be in the wrong driver.

jclub2

Needs emulating the coin double sensor, removing the patch to pass the eeprom test, extending palette to 0x20000 entries (palette_start prevents more than 0x10000), fixing the disalignment between sprites and tilemap (gap in the fence) during play, without breaking the other screens, which are fine; implementing a few missing inputs / outputs and correct clocks.

Missing random number generator, inputs and sound.

jonos

Skeleton driver. I8085A based. No info available.

kingdrby

cowrace - Incomplete dump.

kinst

kinst2k3, kinst2k4 - Upgrade kits.

klax

klax2bl - Bootleg on different hardware.

konamigx

ggreats2, opengolf, opengolf2, racinfrc, racinfrcu - These games use a special ROZ layer generated by the "PSAC4" custom IC which appears to include a height map.

konamim2

Preliminary driver, needs overall better emulation of the M2 system.

konendev

Most dumps are incomplete. Work has been done and at least one romset goes in-game.

konin

Skeleton driver. Z80 based.

kopunch

Boxing bag game. Sensors aren't emulated, so it isn't "playable".

magnum

Preliminary driver. 80186 based.

Uses a custom video controller which isn't fully understood. Mazer Blazer appears to use an MM54104 'Digitalker' speech IC, however, the two speech ROMs are undumped.

mcr

nflfoot - CED-based disk game. Has gory Z80-based serial I/O interface that is not understood. The CED player interface is undocumented. A poor quality rip exists of the video (probably the best we will get). There is a second CED disk with different teams playing which we do not have access to.

mediagx

Mainly just need the inputs hooked up, which are mapped to the parallel port via a JAMMA interface

megadrvb

sonic2mb - Needs correct coin logic (mcu simulation?).

megatech

Incorrect behavior at time out and there are some sms based games which aren't yet fully supported.

Very preliminary driver.

missile

mcombat, mcombata, mcombats - Bootlegs on different hardware.

missilem - This kit combines Missile Command and Super Missile Attack on ddaughterboard plugged into the main pcb cpu slot.

mitchell

pkladiesbl - Needs CPU "decryption" / ordering.

model1

netmerc, swa, wingwar and clones - Guesswork incomplete on the math copro dsp functions and program impossible to dump.

wingwar360 - Needs emulation of the additional boards needed for the R360. Currently doesn't start, waiting for the safety bar to be lowered.

model2

Implementation of the 3D systems is either guesswork (Model 2, 2A) or incomplete (Model 2B, 2C).

rascot2 - Probably part of a multiple unit setup (server, terminals, video boards).

model3

Driver is still preliminary. Most games boot and show something.

monzagp

Preliminary driver. Possibly missing a rom.

moo

moomesabl - Bootleg on different hardware. Sprite ROMs weren't dumped for this bootleg set.

mpu12wbk

Almost skeleton driver.

mpu3

Most games fail to boot, giving the CPU a 'WAIT' instruction then sitting there; some complain about Characterizer (protection) and then do the same; a few boot to show light displays with no LED text; some display misaligned LED text; many run VERY slowly, even when the CPU is inactive (inefficient MAME timer system overhead?).

mpu4

Fruit machine hardware. Not working yet. Needs artwork.

mpu4plasma

Fruit machine hardware. Not working yet. Needs artwork.

mpu4vid

Needs correct implementation of characteriser protection for each game. BwB games need more work: They have a slightly different 68k memory map. The 6850 is at e00000 and the 6840 is at e01000; they appear to hang on the handshake with the MPU4 board. Needs finding out what causes the games to hang/reset in service mode: probably down to AVDC interrupt timing, there seem to be a number of race conditions re: masks that need sorting out with proper blank handling, etc. Currently using a scanline timer to drive an approximation of the SCN2674 scanline logic, but this is perhaps better served as a proper device. Deal 'Em lockouts vary on certain cabinets (normally connected to AUX2, but not there?). Deal 'Em has bad tiles (apostrophe, logo, bottom corner), black should actually be transparent to give black on green.

mquake

A complete mystery. The existing dumps are 100% confirmed. Test mode works. All remaining code is heavily encrypted. Even the original author of the game doesn't recall any encryption, but it is definitely there. It is not done in software; all unencrypted code has been accounted for.

mrgame

Pinball games. Emulation is (almost) complete, but the missing simulation of the tables makes them unplayable.

segas24

sspirtfc - Missing floppy image.

seta

inttoote - Unemulated protection.

inttootea - Incomplete dump?

setaroul - Prelimary emulation.

simple_st0016

dcrown, dcrowna - Slightly different hardware.

mayjinsn -

skeetsht

Preliminary driver.

skylncr

bdream97 - The inputs tend to act out of control at many times. This may have to do with the large number of unknown reads and writes to an I/O port at $66.

s2650 based. Driver is skeleton-ish.

subsino

mtrainnv Subsino sold a "Settings/Clear ROM" for some released titles. These devices are *extremely* expensive (and ultra rare, only sold to big casino corporations), and should be placed in the empty socket to fix a dead board due to NVRAM corruption. A version of Magic Train running on subsino.cpp (unlike mtrain, which is needed to match this program ROM.

summit

Needs inputs, prom decode, sound, artwork (lamps), probably some irq masking and the like.

taitopjc

Preliminary driver

taitotx

Preliminary driver. PC based.

Laserdisc game. Works in theory, but is waiting for a good quality laserdisc dump. Does have a small list of TODO items that could be looked at prior to a disc dump.

thepit

zaryavos - Incomplete dump.

thoop2

Unemulated protection device with internal rom and suicide capabilities (DS5002FP).

tigeroad

f1dream - Collisions are wrong due to unemulated protection.

vectrex

raaspec - Timings and mandatory artwork missing.

vega

Controls aren't correctly hooked up and objects aren't properly positioned.

vegas

warfa - Something is wrong with the on-board ethernet chip emulation. If the chip is hacked out, the game boots, but that's not accurate. There were many rendering issues last time I checked.

roadburn - Sound board is different; with some manual fiddling, you can get it in-game, but it doesn't work particularly well.

nbagold, nbanfl, nbashowt - These Vegas games used a Voodoo Banshee video card. The current 3dfx voodoo emulation has some basic support for the Banshee, but it is pretty minimal. The tricky bit is that the Banshee (and later, the Voodoo 3) have integrated 2D and 3D capabilities, so we need to emulate at least part of a VGA controller in addition to the 3D. These boards also had some new features that require some addition internal reworking of the Voodoo driver.
