Diskbusters v2.0 is another early V-Max loader with a track-sync protection instead of the usual fare.

Attached is the commented disassembly with a short crack tutorial.

Pete, I've sent you a cracked D64 and a G64 image that's had the track alignment modified to pass the protection.

Just a little correction on rewriting tracksyncs back from a g64 to a real disk, it can be done with the right switches, and the right drive speed.

Does nibwrite write G64s to real floppies as well? I thought it just did .nib/.nbz/.nb2 files. And it will retain track sync from a G64 as well? Nice. Didn't know that.

I've updated the document to reflect this, as well as changed the crack so that it's more efficient and only requires editing one non-encrypted sector.

Sure. It writes g64 and d64 directly also and supports all error blocks.
