Another simple, yet efficient protection. Sector 9 in Track 79 is read twice, the EOR checksum has to change, done via “weak” or “fuzzy” bits in the sector. Again: easily defeated with a Floprd() patch. move.w #$9,d0 ; 00CEC0: 303C 0009 bsr .l +$28 {$00CEEE} ; 00CEC4: 6100 0028 move.b d0,$cf2c ; 00CEC8: 13C0 0000 … Continue reading Atari ST Protection: Spy Vs Spy from Databyte
