ChaosKnight has updated the Apple Macintosh emulator for the PSP, the port itself is of the Macintosh emulator Basilisk II, heres whats new:
It looks like POSIX is required for Extended FS. I tried to get around it with writing my own functions but to no avail. Not enough time today. I'll work on it a bit later maybe. I'm taking suggestions for what to work on next (proper color? ethernet? mac os 8? who knows?). I have uploaded a new binary set (for unzipping on your memory stick!) which will load up any HFV or DSK file that is sitting around. No more required startup.dsk... although you can keep it and it will still work.
-- EDIT --
Forgot to put this in. The analog pad moves 2px at a time, which is too much for hitting small controls sometimes, so I made the DPad do 1px. Much easier.
