Well the PowerUP software isn't going to help if you want PPC emulation in UAE... You'll want to figure out some way up integrate the PPC core from something like PearPPC and then find out the timing and interrupt interaction between the PPC and the 68k... Piru might be able to give you some clues... And perhaps Ralph Schmidt... Probably best to ask on the MorphOS dev boards... Many of the old Phase5 engineers are around there.
