Revision as of 05:53, 12 April 2023

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.

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

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.

atarig42

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

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.

bagman

bagmans3 - There's extra code at 0x5f98 - 0x5fa5 that reads a value from $ed01. It's not clear what lives there.

chqflag

Opponent car-to-car collisions direction are wrong.

clshroad

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

coinmstr

quizmstr -

cvs

raiders and clone - Protection is patched out instead of simulated.

ddealer

Undumped MCU, currently simulated.

ddenlovr

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

funworld

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

galivan

ninjemak and clones - Likely missing MCU emulation/simulation for displaying text layer for Ninja Emaki. There is no text displayed when you enter Service Mode when there should be.

goindol

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

goldstar

flt7_50 and clones - DS2401 protection not completely emulated.

gstriker

twcup94 and clones - MCU simulation isn't complete. MCU should be dumped.

igs017

lhzb2, slqz2 - IGS022 protection needs more work.

mgdh - Game ID check is patched out.

spkrform - Poker game enabling forced with a patch.

tjsb - Fails the bonus round protection check (if enabled via DSW), see e.g. demo mode.

jalmah

daireika, mjzoomin, urashima - unfinished m68k snippets.

kakumei2 - Uses protected RNG.

konamigx

salmndr2 and clones, sexyparo and clones - ESC protection emulation incomplete (ships in attract mode).

winspike and clones - Incomplete simulation of the protection provided by a Xilinx FPGA.

magtouch

Protection has been patched out. Needs proper emulation.

mainevt

devstors and clones - Has player-trench collision detection issues, player isn't supposed to go through them.

markham

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

mazerbla

mazerbla and clone - They use a custom video controller which isn't fully understood.

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).

merit

couple and clones - Currently need a kludge because of not understood CRT-209 modules hookup.

mil4000

chewheel - MCU is only partially simulated.

msisaac

msisaac - Missing M68705 MCU dump.

namcond1

abcheck -

ncv2, ncv2j - MCU emulation is imperfect.

nemesis

gradiusb, twinbeeb - Bubble System MCU is imperfectly simulated.

ninjakd2

robokid and clones - Random crashes probably related to protection.

nmk16

hachamf, tdragon1 - MCU simulation not hooked up.

pacman

alibaba, alibabab - Mistery items in Ali Baba don't work correctly because of protection.

pcat_dyn

toursol - The protection has been patched out instead of emulated.

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.

olds, olds100, olds100a - Somewhat playable, but protection simulation isn't perfect yet.

qix

kram3 - Incompletely understood encryption.

segas16a

dumpmtmt - i8751 MCU dump needed: the MCU clearly does more than what's simulated.

skylncr

leadera - A protection check is patched out instead of emulated.

snowbros

yutnori - Protection seems to handle sound.

tsamurai

vsgongf -

vamphalf

wivernwg and clones - They give a protection error after a certain number of plays / coins.

williams

mayday and clones - These games have an unemulated protection chip of some sort which is hacked around in /machine/williams.cpp "mayday_protection_r" function.

wink

wink, winka - Protection module has been reverse engineered but it's still missing something.
