blastar (./7) :
has this ever been verified on real hardware?
I also blindly trusted the NeoDev-wiki '$04: Read track and loop (confirmed)' and never really tested it. I can NOT reproduce it on the real hardware, neither via the direct BiosCall nor via the Z80... there must be something wrong.
maybe the confirmation is because it works with RAINE but this emulator is not accurate.
no luck with:
TOPLOADER + UNIBIOS 3.3
FRONTLOADER (unmodified)
