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.
Missing working simulation of the sensors.
Skeleton driver. GFX / Sound roms are bad and the PIC isn't dumped.
4roses, 4rosesa - Skeleton driver. The program rom is encrypted and it has an undumped MCU which needs decapping or simulation.
The inputs aren't fully understood yet.
acefruit - Inputs aren't fully understood. The real title of the game is unknown.
starspnr - Most likely needs a redump of the program ROMs.

goldmedb - It uses a 68705 in place of the Alpha controller.
ar_dart2 - Bad dump.
Driver recently added and under development.
Skeleton driver. Needs better Acorn Archimedes hardware emulation.
terrafb - This bootleg runs on slightly modified hardware which need proper emulation.
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.
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.

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.

Laserdisc game. Has a small list of TODO items that could be looked at prior to a disc dump.
Annoying VDP-like chip controlling access to video devices. Commands not fully understood, correct readback of data just as important as writes as addresses etc. are stored and it affects future writes. Runs through attract mode with bad graphics, but no guarantees are made that the sprite-list it's currently processing is in the right format, or the right place as everything is written through the 'VDP' device.

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.
Mainly just need the inputs hooked up, which are mapped to the parallel port via a JAMMA interface
monkelf - Bootleg on different hardware.
Incorrect behavior at time out and there are some sms based games which aren't yet fully supported.

Lacking Am29000 core. Documentation and a software simulator are available, fortunately. Work in progress by Phil B.
offroadc - some calculation bug in the TMS32031 (I suspect) causes the clip plane to clip out a number of close polygons, most importantly your truck. As-is, the game is sort of playable, if you like some extra challenge.
crusnexo, thegrid and clones - These Zeus II-based games use a proprietary 3D graphics chip that has no available documentation.

moobl - Bootleg on different hardware.
Mechanical games imported from AGEMAME.
Very cranky hardware - 2 PCB comms system and a particularly bizarre GFX hardware setup.
8-bit CPU board, ton of timers, what looks like a discrete audio alarm tone, 6850 serial io etc. driving a 68k based expansion board with a video chip straight from a Wyse 60 terminal. It's VERY VERY fussy about everything, serial checks, timer checks, interrupt checks, protection chips
Cursory glance at the self tests suggest we at least need a 6850 core that doesn't use hardcoded RX/TX clock frequencies, and an accurate to the point of ridiculous 6840 core, before these'll even look like booting up, let alone having correct video etc.
Skeleton driver.
A complete mystery. The existing dumps are 100% confirmed. Test mode works. All remaining code is heavily encrypted. Even the original author 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.

Menu system difficult to make sense of.
Driver is still in preliminary status.
cyclshtg - Missing (protection?) MCU dump.

Driver has heavy graphic problems. Missing road (two unemulated K053250).
Skeleton driver.
pangofun - PC based hardware, possibly bad / incomplete dump.
Capable of reading back the background layout ROMs for collision, readback method isn't properly understood, so the game doesn't play correctly.

banbam, pettanp - Protection MCU.. seems to be a data (or code?) ROM for it tho.
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.

Protection MCU handles inputs (and winning odds?).
Very strange, may be missing a rom, schematics available.
Skeleton-ish. V30 based, Banking issues, PIC for protection? or sound?
This purely a skeleton driver. Also missing CPU core for Intel i860 CPU.
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, cartfury, 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.
sf2049, sf2049se, sf2049te - Voodoo 3-based, one step beyond the Voodoo Banshee problems
Work in progress by Ville, PPC+voodoo.
