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

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

evilngte, totlvica, totlvicj, totlvicu -

Mechanical game, needs controls simulation.

lcmate2

RTC doesn't remember the time, alarm doesn't work and Reset/On button needs to be added.

magic10

hotslot, magic102, mcolors, mcolorsa, suprpool - Missing dump of the internal rom of the HD6473308cp10.

magicard

Lots to do: proper handling of the 68070 (68k with 32 address lines instead of 24) & handle the extra features properly (UART,DMA,Timers etc.), proper emulation of the 66470 Video Chip (still many unhandled features), inputs, unknown sound chip (it's an ADPCM with eight channels), ,any unknown memory maps, proper memory map and machine driver for magicardj & magicle (different sound chip, extra undumped rom and PIC controller).

Skeleton driver for fruit machine games.

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.

mdisk

It boots from floppy, so presumably only needs an emulated main system to work.

mediagx

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

megadriv

dcat16 - Clone hardware with additional features.

megadriv_acbl

jparkmb, twinktmb - Undumped PIC controls at least coins and dips. Crude simulation causes problems in detecting coins.

megaplay

Interaction between BIOS and 68k side is not fully understood. The BIOS often doesn't register that a game has been started and leaves the 'PRESS P1 OR P2 START' message onscreen during gameplay as a result. If this happens, the games usually then crash when you run out of lives as they end up in an unknown state.

megatech

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

merit

dodgectya, dodgectyb, dodgectyc - Incomplete dump. One GFX rom is in an epoxy block.

meritm

megat5a - Bad dump.

metalmx

Skeleton driver. Extremely complex prototype hardware.

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.

Preliminary driver. Possibly missing a rom.

mpc3000

Preliminary driver. NEV V53 CPU and L7A1045-L6048 sound DSP emulation is preliminary.

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.

Missing timer, banking non totally implemented.

snesb

mk3snes - The undumped MCU (or some other device?) must be providing the 'arcade-side' of the hardware (or code patches?).

spectra

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

spg110

Preliminary driver. Sunplus SPG110 based.

splash

funystrp, puckpepl - Protection, controls eating of dots + other things.

rebus, ringball - Another protected Microhard game.

splus

Driver imported from Agemame. Needs modernisation.

spoker

3super8 - Roms are badly dumped.

spyhuntertec

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.

vectrex

raaspec - Timings and mandatory artwork missing.

vega

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

vegas

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.
