This page is designed to allow for a quick look over all the drivers with a GAME_UNEMULATED_PROTECTION flag (but still working) by giving, as much as possible, an idea on the amount of effort needed to fix them.
kodure, legion, legiono, terraf, terrafa, terrafu - Needs better simulation or decap of the MCU / blitter.
roadriot - ASIC65 for Road Riot not quite perfect.
primrage, primrage20 - Are pretty close, but not quite perfect. There are some sprite offsetting issues still and I'm not 100% sure the gameplay is all there.
tmek and clones - Are interesting. We have a prototype version that plays well, but has no matching sound ROMs so you don't get sound. Then we have a non-prototype version that doesn't play correctly, but has fine sound. In theory, it might be possible to see the decrypted data in the prototype version and understand the process, but not much work has happened here.
chqflag, chqflagj - Position counter doesn't behave correctly because of the K051733 protection.
quiz365, quiz365t - Needs better simulation of the protection device.
birdtry - Better simulation / dump of the i8751 MCU.
onna34ra, onna34ro - Better simulation / dump of the M68705 MCU.
goindol, goindolk, goindolu - Currently protection is simulated with rom patches.
josvolly - Missing MCU dump.
salmndr2, salamndr2a - ESC protection emulation incomplete (ships in attract mode).
winspike, winspikej - Incomplete simulation of the protection provided by a Xilinx FPGA.
lordgun - Protection emulation instead of patching the roms.
daikaiju - 68705P5 MCU internal ROM dump is missing. Protection is simulated.
couple, couplei, couplep -
msisaac - Missing M68705 MCU dump.
ncv2, ncv2j -
hachamf - MCU simulation *might* be wrong/incorrect.
alibaba - Mistery items in Ali Baba don't work correctly because of protection.
dumpmtmt, quartet, quarteta - i8751 MCU dumps needed: the MCUs clearly do more than what we are simulating.
bullet - The decryption key was only partially derived.
targeth, targetha - Needs DS5002FP MCU with external battery ram (32k).
glfgreat, glfgreatj -
wink, winka - Protection module has been reverse engineered but it's still missing something.
