Specific Contributions

The known contributions for this version are, in the order specified in the whatsnew:

  • Nicola Salmoria and Charles MacDonald FD1089 decryption:
    • 100% accurate emulation of FD1089A, FD1089B should be considered 99% because it will have to be verified with other CPUs (it is 100% for all currently supported games).
    • complete tables provided by Charles MacDonald for 317-0018 (Action Fighter), 317-0022 (Dunk Shot), 317-0168 (Aurail).
    • partial tables derived by comparison with the unencrypted versions for Enduro Racer, Alex Kidd, 317-0024 (Time Scanner), 317-0033 (Alien Syndrome, 3 versions), 317-0027 (SDI). (actual working cpus are needed to obtain full tables)
