Sorry guys, finally I should mention that
all my testing has been done in WinUAE and not on a real Amiga. That's all I have access to these days...
I just tried the latest crunched / compressed .ADF using a standard A1200 configuration i.e "2MB Chip RAM" only (but this time without "Cycle-Exact" ticked) and all works perfectly
Can someone with a real / standard A1200 test this disk and report back?
Maybe this disk is good enough to include in the next TOSEC release
