If Kabuki uses an internal memory for storage then this storage must be of CMOS type, thanks to one of the manufacturer product catalogs (VTI) we already know that the Kabuki Z80 core is a CMOS part. We know this from the fact that whenever the cpu loses power input on pin 28 those memory contents are lost and the cpu stops being able to run games, forever.īut let's look for a minute at what's going on here. ![]() ![]() Welcome to the third post in the series, you can access the previous posts here:Īs explained on part one, Kabuki presumably uses an internal memory where it keeps the keys used for program and data code decryption. ![]()
