We are using 20 bits keys with the following subfields' structure:
bits 0-15 is a 16-bits XOR
bits 17-16 is a index to the sboxes table
bits 19-18 is a index to the permutation table
We are using 8 bits keys with the following subfields' structure:
bits 0-3 is a index of 16-bits XOR (only 11 was used in known games)
bits 4-5 is a index to the sboxes table
bits 6-7 is a index to the permutation table
These subfields could be differing from the "real" ones in the following ways:
- Current keys equal to decrypted game code binary 8-bit sum (of each byte's swapped 4-bit nibbles)
- Every one of the index subfields could be suffering an arbitrary bitswap and XOR
- The 16-bits-XOR subfield could suffer an arbitrary XOR which could depend on the 4 index bits (that is: a different XOR per every index combination)
- Of course, the way in which we are mixing 3 subfields in one only key is arbitrary too.
The keys are stored as 32-bits big-endian values in a file.
Real keys provided by cartridge CPLD is only 8bit, bits 4-5 is sbox table index, bits 6-7 is permutation table index.
But it is not clear how 16-bit XOR value derived from 8bit key.
