Could you update the quickbms script to handle encrypted toc cpk files?
the xor key is

Code:

this is a sample cpk

I guess he means to add the following instruction after 'idstring "CPK "' in the cpk.bms script:

Code:

filexor "0x5F 0xCB 0xA7 0xB3 0xAF 0x5B 0x77 0xC3 0xFF 0xEB 0x47 0xD3 0x4F 0x7B 0x17 0xE3 0x9F 0x0B 0xE7 0xF3 0xEF 0x9B 0xB7 0x03 0x3F 0x2B 0x87 0x13 0x8F 0xBB 0x57 0x23 0xDF 0x4B 0x27 0x33 0x2F 0xDB 0xF7 0x43 0x7F 0x6B 0xC7 0x53 0xCF 0xFB 0x97 0x63 0x1F 0x8B 0x67 0x73 0x6F 0x1B 0x37 0x83 0xBF 0xAB 0x07 0x93 0x0F 0x3B 0xD7 0xA3" 0x10

But I think there is something missing, for example the format is not 100% the original (I tried also to use it against the manually xored file).

Each table is xored with that key.
you can tell by the 0xFF 00 00 00 flag on unencrypted files vs encrypted files.
If i decrypt the tables. then run quickbms on it its fine.
So whenever the file table gets read it just needs to have the xor applied when the flag is 00 00 00 00.
