I just found a Japanese port of UAE for the Zaurus
. It runs a bit better than the other one, and I thought of a trick to get it running much faster. I've got Turrican II running on it (pictures when I get home). It would be fully playable except for the fact that the frame skip option doesn't seem to work. If I can get it skip a couple a frames, I can probably get 100% Amiga speed.
At some point I'll have to have a go at compiling it myself because there are thing that need doing...examples are that the touch screen works like a single-button mouse and that joystick can't be mapped to the keyboard properly.
