Preliminary driver. Hangs after booting irix from miniroot.

4enlinea

Needs proper UM487F device emulation. CPU logic seems quite off.

4enraya

Preliminary driver. Mechanical / screenless system. Uses a Z8 based MCU.

amiga

Amiga chips emulation lacks a lot of features.

ampoker2

arizna10 - Undumped PIC provides protection. Currently can't exit operator mode to get in game.

artmagic

shtstar - Runs on different hardware.

asst128

A ROM isn't dumped.

astrcorp

astoneag, dinodino, magibombd - These games have been mostly decrypted. There's still something unclear about the first few hundred bytes, which aren't correct. The current suspect is they get overlayed by code provided by a protection device. For now MAME patches the reset vector, which then leads the games to boot but show a ROM error message, since they fail the internal checksum.

hacher, winbingo, winbingoa, zoo These should be at the same state of astoneag, but don't show anything on screen.

atari400

a1200xl - Bad dump.

a65xea, a130xe -

atarigx2

All of these games suffer from some advanced protection that affects them in different ways. Through some magic accesses in memory, data can be decrypted using some special key sequences that are not entirely understood. It's possible to find all possible data sources, run them through the decryption process on the real PCB, and then encode that information in the driver, and for some of the games it has been done. Only rrreveng and clones are missing.

rrreveng and clones - Unemulated protection. It's possible the same method used to break Moto Frenzy's protection could be used.

atarist

Emulation still preliminary. TODO is on top of the source file.

Needs better understanding of the master/slave communications, better EEPROM and NVRAM hook-up.

jade

If you hit a key as soon as it is started, the system will present a prompt and work. Otherwise it runs into the weeds because the rom banking isn't yet emulated.

jaguar

Needs display mode 384x200, sound, possibly tape and network. Floppy interface isn't understood, though it works enough with the only disk available.

jungleyo

With a clean NVRAM MAME needs to be soft reset after init or the game will trip a '1111 exception' (caused by invalid opcode executed at 0x102, incomplete decryption most likely); likewise anything in the 0x100-0x1f7 range doesn't seem valid at all; the game sometimes expects 1+ coins even if player has available points (and freezing with "COIN" text blinking), very unlikely to be intended behaviour?

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 - They get stuck during boot.

heatof11 - Hangs if Japan is selected. Timing related, as setting perfect interleave fixes it.

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. 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.
