MNW

This page is designed to allow for a quick look over all the drivers with a MACHINE_NOT_WORKING flag by giving, as much as possible, an idea on the amount of effort needed to fix them.

20pacgal

25pacman - Newer set on slightly different hardware.

2mindril

Missing working simulation of the sensors. Requires a major rework of the artwork sub-system.

39in1

19in1, 48in1, 48in1a, 48in1b, 60in1 - Seem to have a slightly different encryption (more conditional XORs) which still needs some work.

4in1a, 4in1b - These have been decrypted, currently boot but stuck at 'Hardware Check' with an error. Need adjusting of the cpld_*() methods.

rodent - Should be correctly decrypted but expects something different from the CPLD (probably).

3do

Emulation is stil preliminary. Needs DSPP core properly hooked up (should be similar if not same to the one used by the later Konami M2 HW).

4dpi

Preliminary driver. Hangs after booting irix from miniroot.

4enlinea

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

4roses

Skeleton driver. The games' program rom has been decrypted, but they have an undumped MCU which needs decapping or simulation.

8080bw

invasionrz and clone - Bootlegs on slightly different hardware.

sisv1 - Some ROMs aren't dumped.

aa310

RISC OS Draw app uses unimplemented copro instructions; needs ABORT line support to the ARM core; missing hard disc controller, serial interface, 82c711, podules expansions.

a5105

ac1scch - Hardware differences aren't emulated yet.

acefruit

acefruit - Inputs aren't fully understood. Video in bonus game needs fixing.

starspnr - Most likely needs a redump of the program ROMs.

acommand

acommand - Inputs aren't fully understood. Requires a major rework of the artwork sub-system. Needs to be merged with cischeat.cpp driver.

adacp150p

ASCII printer adapter. Does not do much more than pass the extensive self-test.

adp

Driver seems almost complete, still marked as not working.

agat

Similar to Apple II (same bus architecture, keyboard and floppy interface), but video controller is completely different.

agat9 - Needs memory banking. Extensive todo at the top of the driver.

airraid

airraid, cshooter - GFX roms in black 'blobs'.

aleck64

mtetrisc - Uses additional 2d sprite overlay for tetrominoes gfxs, mostly working minus gfx decoding itself.

alesis

The driver seems quite flashed out, but has no notes on what's missing.

alg

Laserdisc games on Amiga 500 hardware. They all work in theory, but are waiting for a good quality laserdisc dump.

alien

Skeleton driver (SH4 based system). Has 2 MPEG2 decoder chips.

allied

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

alpha68k

sbasebal, sbasebalj - MCU simulation is inaccurate / unverified, calculates pitch speeds at very least.

alphasma

Needs work on ADB and PS/2. The charset ROM is wrong.

alphatpx

Preliminary driver. Currently only shows the initial boot message. I8085A based.

altos5

When running MP/M, dir command crashes the system.

amaticmg

Emulation of the type 2 and 3 boards is preliminary, thus only suprstar (board type 1) kinda works, though it errors out when inserting coins.

amerihok

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.

amstr_pc

The driver seems quite flashed out, but has no notes on what's missing.

amust

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

artmagic

shtstar - Runs on different hardware.

astoneag, 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 the fail the internal checksum.

dinodino - Decryption should be on par with the others but code jumps early into the weeds after RTE.

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

magibomb, magibombb, magibombc, magibombe - They sorta work, seem to run a bit to quickly.

astrocde

tenpindx - This game used a physical hockey puck which the player slid down the bowling alley. Sensors on the other end picked up the location and velocity of the puck and simulated the pin behavior. Requires simulation of this input interface in order to be considered working.

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.

banctec

Preliminary driver.

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.

vidchal - Needs videotape support.

hh_hcms40

gckong - random lockups (tap the jump button repeatedly): mcu stack overflow, works ok if stack levels is increased, 38800 B rev. has more stack levels? Or it could be a race condition: irq happening too late/early.

hh_pic16

pabball, uspbball - Preliminary drivers.

hh_tms1k

bship and clone, elecbowl - As far as MAME is concerned, the game is emulated fine. But for it to be playable, it requires interaction with other, unemulatable, things (eg. game board/pieces, playing cards, pen & paper, etc).

jackpool

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

jaguar, jaguarcd - Currently the driver is geared toward supporting the cojag arcade games. Jaguar console support is very poor, most games aren't properly playable or have severe performance issues or crashes related to the unsafe blitter code.

jokrwild

juku

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?

jupiter

Preliminary driver. Devices aren't connected yet.

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 - They get stuck during boot.

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

konblands

mccpm

FDC is implented but there's no software to test it.

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

barek2mb - PIC is dumped but hasn't been hooked up yet. Crude simulation causes problems in detecting coins.

SunPlus side isn't hooked up.

megadriv_vt_hybrid

VT side isn't hooked up.

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.

menghong

HY04 protection needs simulation (controls tile RNG at very least and possibly colors). EEPROM isn't hooked up yet.

micropin

pentacup - Pinball hardware. M6800 based

microtan

mt6809 - Uses a different CPU from the other machines in the drivers, still preliminary.

vf - Collision detection is broken due to imperfect TGP RAM port emulation or hookup.

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.

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

mpf1

mps1230

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. 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.

mpz80

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.

Cassette isn't working yet.

oneshot

maddonnb - No program roms on this set. GFX have misplaced tiles when used with other program roms, so this is a different license / revision.

pc100

pc1500

pc2000

Z80 based.

pc4

pc6001

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?).

pc8001

pc8401a

pc8801

pc88va

pc88va jumps off the weeds with two bogus opcodes (noted in source)

pc88va2 no SW loads up due of missing μpd71071 DMA demand mode (required by the FDC device).

Unemulated plain PC8801 compatibility mode.

pc9801

Most BIOS dumps aren't genuine and/or not properly identified. Several of them doesn't surpass POST check, either because they are effectively bad dumps or have extra unemulated HW features (cfr. Epson line pc386m, pc486mu)

Keyboard is simulated (no MCU dump available).

Needs serious split up into the various model/device flavours.

SW compatibility is hit or miss for both floppy and CD-ROMs,
