Ah, duplicate sector IDs. Ran into that not too long ago: https://oldvcr.blogspot.com/2023/08/cracking-designwares-gra...

V-MAX! and Rapidlok were like deep magic, though. I never successfully cracked a title with that by hand myself.

Interesting to see this stuff. I really enjoyed cracking this stuff back in the day, just for friends, but took a different approach of using sector editors to read the code on the disk to find where the check was done to see if the protections was present and replacing it with NOPs ($EA) or what was more interesting was how the code that did the check was also moved about the disk, I remember seeing for a particular piece of code it did a B-E (Block Execute) on Track 5 Sector 5. I could plainly see the protection check on that spot on the disk. My young self was very excited about working it out. The puzzle of copy protection was more fun than playing the actual games. Very freuqntly the directory tracks (18?? I think) were overwritten but it was obvious looking over the disk to see the headers for various programs and the load start address so it was easy to rebuild. Golden times. I've coded since then, and only recently have stopped as AI has finally got better than me!!
