I have probably said some of these previously what I need before I hopefully find some AROS interest again...
- Better compiler. GCC m68k output is crappy. (no register parameters, seems to prefer absolute addressing instead of PC-relative, makes far too large code.. And so on.)
- Exactly defined small problem cases. Not "everything is too slow", "programs don't work".
- Less annoying hype about Vampire and Aros
EDIT: - Amiga side drivers, especially small low level ones are always fun to do.
