cool, thanks mate, I'll look and see if I can find where I'm going wrong.

Yes, mame reads in big endian and converts to little endian when saving the decrypted rom. But that's not the problem. The decrypted values are different. I believe my script is missing something that is not in cps2crypt.cpp.

Yes, if I dump in mame, for example, from the range of rom03, 0x0000 to 0x07FFF, everything is decrypted opcodes and data. This would not be the problem for me but rather trying to understand how mame applies the decryption script. In my script I adapted the entire decryption part of mame...

Hello, I understand how mame uses the key file, it takes the 20 bytes of the key and converts it into the master key used in the decryption script. I still don't understand how it gets the data from the ROM, I adapted an external script to mame, I added logs, the logs are the same as mame, but...

Thanks for answering friend, yes I know that the code I passed is from the infinity key, I just passed it as an example I know how it works. The doubt I have is regarding the decryption of mame that even using a 20 byte key to decrypt, in the logic of the cps2decrypt.ccp file it uses 64 bits...

Hi, I would like to ask you a question about the relationship between the 20-byte decryption key used in real cps2 and the decryption key used in mame, which uses two 32-bit pairs. Is it possible to generate the key that mame uses using the 20-byte key or vice versa, and how is this done? for...

Hello everyone, is it possible to record PAL G to cps2 on the T48 programmer and if so how to configure it?

Hello, I'm looking for the killer instinct 2 board processor to purchase, idt79r4600-100ms. Does anyone have it for sale?

Obrigado pela resposta. Consegui consertar o defeito, apesar da eprom de teste não apresentar erro de ram do objeto, após trocar as ram do objeto funcionou normalmente.

Verifiquei a conexão com a placa A e já testei em outra placa A. E o problema continuou na placa B.

Hello, could anyone help me? I have a B board with a graphics error, as shown in the video. I've already done some tests, like testing other roms and maskroms, changing PAL's. I tested with the rom tester and there was no error.

Hello friends, I have a problem with sound initialization and BAD ram memory on a B cps2 board, marvel vs capcom game. I've already done several checks. - I tested the card on another board A and the same problem occurs; - I've already changed Roms 11 and 12, Roms 1 and 2, pal G, 74lS257 and...
