I'd suggest using longer fingerprints like the stack initialization,
horizontal positioning, 48 pixel code etc. The are some variations,
but maybe some fuzzy logic would be helpful.

Or just take some typical ROMS for each system and "CloneSpy" them
against the ROMs you would like to identify.

Have fun!
