yup, true.

my idea, regarding this:
an emulator might be done quicker using the 030's pmmu to remap the blitter variables to
valid ram-space. a TT-MFP ISR not affected by most ST progs (naturally) could then run the emulator checking for these pseudo $ffff8a00.w registers in order to treat them like blitter-internals. still, someone would need to implement this and i won't be that person :).
