I can testify that the untouched, full/registered Quake II pak0.pak DOES in fact work with PQ2 flawlessly. I have a iPAQ H3600 with 64MB RAM and a 1GB Microdrive. Transfer rates are fine too, not much slower than I remember playing them on my PC (years ago.. hehe).
All I need to do now is to come up with some good controls for it!
By the way.. is there some way to turn the sound on, or is it hardcoded off? I would suggest (after optimizations/finalization of the code) that you have two autoexec.cfgs - one defaults to sound off (which would exec if the user doesnt do anything).. and another which defaults to sound on, if they decide to rename that to autoexec.cfg.
Multiplayer would be FUN with this... even with the cell phone modem on this!
