Do you have any URLs handy on this format? I guess you've been refering to the G64 format here...? Also, are there any utilities for dumping disks to the G64 format? (Lando owns the original disk version of Mercenary, which seems to have some copy protection in it...)

Yeah, after all we have a complete CPU emulation already ;-
) Seriously, peeking into the disassembly of the 1551 ROM it seemed that it uses the memory area $4000-$4004 for communication with the plus/4. So, on the other side, this should be mapped to the $FEF0-2 addresses somehow (maybe not?).
