''' goldmedla, golmedlb ''' - The current handling never really accesses video banking other than boot time.

''' 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.

Latest revision as of 06:47, 28 November 2024

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.


alpha/alpha68k

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

skysoldr and clone - MCU simulation is incomplete (unemulated boss time out behaviour).

alpha/meijinsn

Protection simulation isn't right, there is a problem on the selection screen, it's usually not possible to choose tsume shogi (3 difficulty levels).

astrocorp/astrcorp

astoneag, dinodino, hacher, winbingo, zulu - ROM overlay protection is patched for now, need proper implementation.

magibomb, magibombe - Protection isn't emulated but they seem to mostly run.

atari/atarig42

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

atari/atarigt

primrage and clones - 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.

dynax/ddenlovr

quiz365, quiz365t - Needs better simulation of the protection device.

igs/funtech

igs/pgm

drgw3 and clones - DMA protection device non completely emulated (DMA mode transfering 68k code to RAM is not emulated).

dwpc - Missing proper ARM internal ROM dump, currently hacked, needs reset before working.

kov, kov115, kov100, kovplus, kovplusa, kovsgqyz, kovsgqyza, kovsgqyzb - Arm is simulated, rom can be extracted and emulated.
