If so, then it's likely to be 4am's crack. The original won't boot from any .dsk-style format.

Depending on your intention, you might want to use my 1-sided ProDOS-based version instead. It fixes the game-crashing bug in level 6.

It's not 4am crack - disk pile is too old for that. Speaking of disk piles, a group in Bulgaria dumped their copy-protected disk pile into a custom format (via http://forum.agatcomp.ru//viewtopic.php?id=158)
This is the output of a sampler running on 100 MHz clock. File is just stream of 16-bit words,
little endian. So each sample is with a resolution of 10 ns. No further structure.

Short Apple II program "scans" 36 tracks, including the quarter tracks in-between. Total should be
141. The board just captures (passively) the RD signal from the floppy drive. Each track is
scanned about 8 times. That's why the huge size.

Each sample denotes the width of a pulse (the time period between two pulses), so in a way:

- value about 400 (4 us) is bitstream "1"
- value about 800 (8 us) is bitstream "01"
- value about 1200 (12 us) is bitstream "001"

And samdisk can sort of read that now. One sample dump is normal dos 3.3 disk, another is (probably uncracked) Autoduel disk -- first track uses non-standard epilogues (AF 5x xx).
