+acadiel Posted February 18, 2018 Share Posted February 18, 2018 Does anyone have disk images of these three apps? I believe they used some sort of rudimentary copyright protection. My disks are unreadable. Quote Link to comment Share on other sites More sharing options...

+Ksarul Posted February 18, 2018 Share Posted February 18, 2018 Quality 99 Software would always leave one sector on one of the unused tracks unformatted and set pointer-wise to the number of one of the other sectors on the track. Then the program would try to access the sector several times as a test--if at least one of the tests hit the bad sector, the program assumed the disk was genuine. If all attempts found the sector--it assumed the disk was fake and exited the program. 4 Quote Link to comment Share on other sites More sharing options...

apersson850 Posted February 19, 2018 Share Posted February 19, 2018 I remember I spoke with Maurice E.T. Swinnen when I had figured out how the copy protection worked. He laughed a bit and said "I appreciate if you keep it to yourself." 1 Quote Link to comment Share on other sites More sharing options...
