act/apricotf

Needs CTC/SIO interrupt acknowledge, CTC clocks and sound emulation.

act/apricotp

Needs devices, LCD and sound hook-ups.

act/apxen

Needs boot ROM disable, wrap around mode, floppy, DMA, harddisk, keyboard, RS232, printer, colour graphics board.

alpha/champbas

tbasebal - M68705 MCU isn't emulated yet.

altos/altos2

Keyboard not dumped and emulated.

altos/altos486

odeontw - 'Invalid NVRAM', accesses area $6xxxxx and claims invalid RAM config if bypassed.

odeontw2 - Resets halfway thru "please wait" in service mode, therefore NVRAM cannot be inited.

amiga/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.

amirix/wxstar4k

M68010 based. Cable head-end unit. Very preliminary.

ampro/lbpc

PC. V40 based. Inputs aren't hooked up.

atari/atari400

a1200xl - Bad dump.

a65xea, a130xe -

atari/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.

atari/atarist

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

atari/atarisy2

paperboyp - Prototype with possibly different hardware. Some program ROMs didn't read consistently and are suspected bad. GFX ROMs weren't dumped for this set.

atari/atarittl

tank - Netlist has been added but needs debugging and it runs very slow.

atari/atetris

atetrisb5 - Uses a large TTL board as substitute for Slapstic and Pokeys. Currently unemulated.

atari/badlandsbl

Inputs aren't correctly hooked up, missing sprite-tilemap priority, colors. Sound hw isn't correctly hooked up.

atari/bartop52

Coins and timer were handled by Bartop system bios. Since bios dump is not available, regular Atari 5200 bios is used and game is marked as not working. Game cart is also marked as bad dump as it is done in "console style", i.e. one file for all game data.

atari/bwidow

bwidowp - Prototype on different hardware.

atari/bzone

dsrtwars - Bootleg with different sound system. Mostly works but sound is very badly emulated.

atari/mediagx

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

atari/metalmx

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

atari/quizshow

Missing tape dump and GFX ROMs need redump.

atari/tank8

tank8a, tank8b, tank8c, tank8d - Bad / incomplete dumps.

att/unixpc

DIVS instruction at 0x801112 (the second time) causes a divide-by-zero exception the system isn't ready for due to word at 0x5EA6 being zero. Code might not get there if the attempted FDC boot succeeds; FDC hookup probably needs help. 2797 isn't asserting DRQ?

ausnz/amust

Lots of work still needed. Lacks software to further improve emulation.

ausnz/dmax8000

Needs parallel port, centronics port, AUX serial port and FDC/FDD/HD setup.

ausnz/labtam

Needs emulation of additional cards.

ausnz/mbee

mbee128, mbee128p, mbee256, mbee56, mbeepp, mbeett - Hardware differences haven't been emulated yet.

ausnz/poly

banctec/banctec

Preliminary driver.

bandai/rx78

Inputs might be incorrectly hooked up.

barcrest/mpu1

Missing layouts.

barcrest/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?).

barcrest/mpu4union

Fruit machine hardware. Not working yet. Needs artwork.

barcrest/mpu4unsorted

Fruit machine hardware. Not working yet. Needs artwork.

barcrest/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.

nakajima/nakajies

Banking not fully understood, keyboard communications are partially hacked and misses PCMCIA slot.

namco/20pacgal

Undumped MCU dump (i8049, controls tape and keyboard). We currently hack tape loading to directly inject contents directly into RAM, would be hairy to support without the actual dump.

Needs daisy chain support for all connected devices that can send an irq event, emulation suffers from irq miscatches especially from keyboard and timer.

FDC is unemulated (unknown part #), it also diverges between pc6001 and pc6601.

Video chip is a M5C6847P-1, a derivative of MC6847, later pc6001mk2 uses a(n unknown part #) superset with black instead of green as typical background pen and a new "Mode 5" gfx, which can do nasty mid-scanline effects (cfr. Tiny Xevious Mk 2, where it draws score display portion with different mode than gameplay).

pc6001mk2 also has a μpd7552 voice chip, unemulated (cfr. Chrith Ai no Tabidachi / クリス 愛の旅立ち intro)

pc6001sr is yet again a superset of the older HWs, no way to surpass the initial PC-6001MK2SR World screen (again irq misfire off the bat?).
