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


alinvade

16 bytes are protected in the c*** range (see notes on top of the driver. Game seems to work fine even without protection simulation, though.

alpha68k

sbasebal and clone - MCU simulation is incomplete (calculated pitcher launching speed). See driver for notes.

atarig42

roadriot, roadrioto - ASIC65 for Road Riot not quite perfect.

atarigt

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

Opponent car-to-car collisions direction are wrong.

clshroad

firebatl - Protection, possibly provided by the Z4 device at A8.

funworld

mongolnw, soccernw - Need to hook the missing microcontroller (TSC87C52-16CB) to emulate this game properly.

galivan

goindol, goindolk, goindolu - Currently protection is simulated with rom patches.

gstriker

twcup94, twcup94a - MCU simulation isn't complete. MCU should be dumped.

gsword

josvolly - Missing MCU dump.

igs017

tjsb - Protection is worked around, needs simulation.

jalmah
