Characters are simply 0 thru F, with their usual numbers (0 thru 15, I mean 0000 thru 1111).

Codes look like these: xxx-yyy or xxx-yyy-zzz


how to manipulate xxx-yyy codes
0000 1111 2222 3333 4444 5555

5555 2222 3333 4444 0000 1111


how to manipulate xxx-yyy-zzz codes
0000 1111 2222 3333 4444 5555 6677 8899 AABB

5555 2222 3333 4444 0000 1111 BB66 77AA


Things to note:

  • Bold here means it's inverted, or a NOT gate if you will.

  • In the zzz part (6677 8899 AABB) the bits have to be in a certain way: 8899 is equivalent to 6677

  • In the GameBoy, the 6th character (the last y in yyy, or the 5555) can only be values from 8 thru F.

  • In the GameGear, the 6th character (the last y in yyy, or the 5555) can only be values from 4 thru F.

Those last 3 are for error checking.
