English Amiga Board - View Single Post - How did those dual-format Amiga/Atari ST releases actually work?

The ones that i've looked at don't work like that. Track 0 has a full set of 11 sectors for the Amiga and 9 sectors for the PC/ST.

You can open up a disk sector editor and see this quite easily on the amiga using DF0: and PC0: at the same time.

The rest of the tracks either show up as valid Amiga or valid PC tracks (usually either one side Amiga and the other ST or lower tracks PC and higher tracks (40+) Amiga.

Based on this I can only assume that both treat side 0 as the opposite physical side.
