Sega FD1089 decryption

While I was gathering information about how various Sega encryptions worked, it became obvious that some had a lot in common. So I decided to regroup all the decryption routines into the same software, to be able to capitalize on previous work instead of starting from scratch when working on a new decryption.

I just finished adding FD1089A/FD1089B decryption to the software, meaning that I can generate decrypted sets for PCBs using this kind of encryption. So far Aurail is done (sets 317-0167 and 317-0168), and checksums are automatically fixed. You’ll be able to get them from Porchy’s when the sets will be uploaded.
I’ll try to add more decrypted sets when I have some spare time, but if you need one quick just drop me a line 😉

Next step decryption wise will be to move FD1094 decryption code to the new software. After that I’ll have a look at System 24 FD1094 (floppy drive based), and MC8123 (Z80 based, which I’m far from being fluent with :p

Cheers !
