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

All games but 39in1 - 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. Current stall point is unemulated DSPP core.

4enlinea

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

4roses

Skeleton driver. The games' program rom is encrypted and 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.

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. Requires a major rework of the artwork sub-system. Needs to be merged with cischeat.c driver.

adp

Skeleton driver. Todo: "Almost everything."

11beat - crashes at kick-off while using the DRC, works with the interpreter. doncdoon, hipai, kurufev, mayjin3, mtetrisc, srmvs, twrshaft - Incomplete N64 hardware emulation. mtetrisc uses additional 2d sprite overlay for tetrominoes gfxs, mostly working minus gfx decoding itself.

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.

sbasebalj - MCU simulation is inaccurate / unverified.

amaticmg

Emulation of the type 2 and 3 boards is preliminary, thus only suprstar (board type 1) works.

amusco

Needs i8259 and irqs emulation, understanding of how videoram works (tied to port $70?) and inputs aren't worked out yet.

arachnid

Mechanical game. Needs artwork with lamps support.

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.

astrocorp

westvent, winbingo, winbingoa, zoo - These games need decryption.

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.

atvtrack

Skeleton driver.

avt

Needs CTC and daisy-chain.

badlands
