  • Can you format a disk with each boot block and just extract it from the disk image? The docs say there are six options. Commented Aug 22 at 14:40
  • @fadden This option is only written in the code... It cannot be written through this program. Commented Aug 22 at 14:45
  • @fadden It goes as the seventh in a row. If you change the boot block 7 times, it will return to the standard one and so on ad infinitum... Although it is only in the code and can only be extracted by writing it through this program (probably?) But I pulled out a non-working piece of code and checked it through an antivirus from the same group. It detected Apocalypse II Commented Aug 22 at 14:53
  • If the boot block is in there, you'll either need to fix the list count so the program actually uses it, or identify where the block lives and extract it. As noted in an earlier post, the program has been deliberately obfuscated to make reverse-engineering difficult, and may have scrambled some of the data (e.g. strings in the hex dump show "Load Runn", rather than "Load Runner"). Your best bet is probably to trap on keyboard accesses from an emulator debugger, figure out where the 'B' key is being handled, and patch that code. Commented Aug 22 at 15:07
