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.
coinmstr
quizmstr -
cvs
raiders and clone - Protection is patched out instead of simulated.
ddenlovr
quiz365, quiz365t - Needs better simulation of the protection device.
equites
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.
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
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, winspikej - 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.
merit
couple and clones - Currently need a kludge because of undumped CRT-209 modules.
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 -
pgm
drgw3 and clones - DMA protection device non completely emulated (DMA mode transfering 68k code to RAM is not emulated).
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.
seta
crazyfgt - A protection check at boot 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.
