MNW

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

2mindril

Missing working simulation of the sensors.

39in1

48in1, 48in1a - Games other than 39in1 on this hardware have substantially harder protection and are double-encrypted in a way that would be very difficult to emulate.

3do

Driver moved from MESS to MAME, since there were arcade games based on the 3DO. Emulation is stil preliminary.

4roses

4roses, 4rosesa - Skeleton driver. The program rom is encrypted and it has an undumped MCU which needs decapping or simulation.

8080bw

modelr - Some issues with inputs and the shifter emulation.

acefruit

acefruit - Inputs aren't fully understood. The real title of the game is unknown.

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

acommand

acommand - Inputs aren't fully understood.

adp

Skeleton driver. Todo: "Almost everything."

aerofgt

Bootleg on different hardware, similar-looking to spikes91, includes roms from spikes91 and svolley. Possibly an svolley bootleg on spikes91 h/w?

11beat, doncdoon, hipai, kurufev, mayjin3, mtetrisc, srmvs, twrshaft - Incomplete N64 hardware emulation.

alg

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

alien

Skeleton driver (SH4 based system).

alpha68k

goldmedb - It uses a 68705 in place of the Alpha controller.

amaticmg

am_mg24, am_mg3, am_mg3a - Emulation of the type 2 board is preliminary.

arcadia

ar_dart2 - Bad dump.

aristmk4

86lions - Runs on earlier, slightly different hardware.

cgold2, fhunter, fhuntera - These US-based games require note acceptor and printer support.

clkwise - Needs redump of the program ROMs.

atari_s3

Pinball games. Skeleton driver.

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 might be 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, but it is tedious work at best. Below is the status of each game:

motofren - Has some obvious gameplay glitches. Not much work has been done to understand the protection on this one.

spclords - Has had some of its data decrypted, which is why the palette during attract mode looks ok. But in game there are many problems lurking.

comebaby

Skeleton driver. Game runs on a Pentium (I/II/III?) class machine running Windows 98!

coolridr

Skeleton driver. Uses SH2 + SH1, 68k etc. Dual screen game, plays like a cheap korean rip-off of Outrunners (suspected to be recompiled from the same code ;p). CPU comms don't make sense, interrupts don't make sense.. somebody mentioned that the SH1 has 'extra' features, but according to dox it's plain sh1, and the sh2 core should be 100% backwards compatible. it SHOULD be possible to get this working, or at least doing something more and would be a good / interesting project for somebody.

moo

moobl - Bootleg on different hardware.

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

Mechanical games imported from AGEMAME.

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.

st0016

mayjinsn -

statriv2

cstripxi - Laserdisc game in need of laserdisc dump.

quaquiz2 -

tripdraw -

stepstag

Missing hard disk dump. Hardware is similar to Tetris Plus 2.

stv

decathlt - Funky DMA/decompression protection (reads gfx data via protection chip, descramble / decompress? scrambled registers).

decathlt, decathlto, elandore, ffreveng, twcup98 - Protection. astrass suffers from it too, but it's kludged to work.

findlove - Controls broken.

finlarch, smleague - Randomly hang / crash. They work with a ridiculous MDRV_INTERLEAVE number, might need strict SH-2 synching.

magzun, techbowl, micrombc - I/O errors.

nclubv3, pclub2 and clones, pclub3, pclubpok, stress - Unemulated printer.

sfish2, sfish2j - CD handling broken. Needs MPEG decoder.

vfremix - Texture upload issues in some cases, see source.

su2000

Preliminary driver.

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.c (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.

suna8

brickzn, brickzn3, sparkman, starfigh - Protection / encryption (custom CPU modules containing Z80 + encryption logic).

footchmpbl - Bootleg on different hardware. It has very different hardware registers.

taito_f3

bubsymphb - Bootleg on different hardware. Backgrounds don't show up.

taito_o

Driver still in preliminary stages. TODO: inputs (coins), NVRAM, sprite priorities, dips, interrupts (sources).ö

taitoair

Possible 320c25 bugs. Possible m68k-c25 communication issues. Not easy, the c25 code is hard to read, probably interesting.

taitogn

gobyrc, rcdego - Custom inputs need calibrating.

nightrai - No background / enemy sprites.

sianniv - IRQ at the wrong time.

zooo - Missing most of the playfield.

taitojc

dangcurv - DSP bug causes missing 3D.

taitopjc

Skeleton driver. Requires TLCS-900 CPU core to make progress.

taitotz

Skeleton driver. Requires TLCS-900 CPU core to make progress.

taitowlf

Preliminary, PC+voodoo.

tank8

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

Preliminary, maybe protection.

tcl

Skeleton, decryption incomplete.

tehkanwc

tehkanwcc - Bootleg with different inputs.

tetrisp2

nndmseal - Missing camera and printer emulation.

thayers

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).

timeplt

bikkuric, chkun - Run on slightly different hardware.

Needs laserdisc dump. Laserdisc player models used by this game are unemulated.

tmnt

ssridersb - Bootleg on different hardware. Bad dump.

ssriders2 - Bootleg on different hardware.

tmspoker

Preliminary driver.

toratora

Very strange, may be missing a rom, schematics available.

tourvis

Lacks complete jamma interface emulation.

trackfld

trackfldnz - Bootleg on different hardware.

trucocl

You can't coin-up after first game over.

trvmadns

Random hangs, probably due to incorrect question banking.

ttchamp

Skeleton-ish. V30 based, Banking issues, PIC for protection? or sound?

twinkle

Preliminary driver. TODO: Sound (IDE DMA, finish communications), DVD, Harddrive, 16seg led font.

vamphalf

mrkicker - The game stops booting / working properly after you get a high score, or if you don't have a default eeprom with valid data. It's never worked properly, CPU core issue?

vcombat

Partially working driver. Most of the memory maps for all four CPUs are complete.

vectrex

raaspec - Timings and mandatory artwork missing.

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.

nbashowt, nbanfl - 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.

cartfury, sf2049, sf2049se, sf2049te - Voodoo 3-based, one step beyond the Voodoo Banshee problems.

vicdual

headonsa, headon2s - Won't coin up.
