If you are having problems finding or using cheats for an Emulator (particularly MAME/MESS) or have found a trick that you wish to share this is the place to do it. But please read the Cheat FAQ first.
cheat engine, so I think it needs a different memory region than in this cut'n'pasted sample:
segacd,:maincpu,1CB65E34,d,665347,-----TESTING
Also, had tried ":segacd:segacd_68k" variant, so what other variants are there please. An EXHAUSTIVE LIST would be helpful for not just this case, but future references! Thanks!
