CAPCOM VS SNK PRO [GDL-0004]

Post by majorpbx » Sun Jun 02, 2019 10:25 am

Let me know if I'm missing anything. I am still working on dumping the security PIC's, one day I'll be able to confirm the PIC DES Key's. Let's just say at this point the Key listed is a best guess :wink: . The SNKGD_SL.bin file is decrypted and toying with including the encrypted hash's as well. The CHD (basically compressed complete disk image) file is for MAME and is used to run the arcade game, which decryption (using PIC file) is done on the fly while loading the game just like a normal NAOMI system.

This was already verified and in the dats, as seen in this post.
It also matches files extracted from MAME 0.210 version CHD.

I am not familiar with PICs, decrypted files and the like much, so I can't give any particularly useful ideas about dumping or creating these.
In the TOSEC dats, we are datting the actual GD-ROM files. The rest can be derived from them AFAIK (but it's great that you are including this info in your posts!) :D
