i can just barely play portrait mode on my 206mz ipaq, its just those places where you can see more than 20 meters in front of you, i seriously couldn't imagine playing PQ on a 131mhz pocket pc, 2-4 fps isn't even enough to navigate properly, o/c ing to 168mhz will make it just playable in portrait mode, fullscreen is almost twice the size of portrait so expect about half the framerate 1-2fps at 131mhz or 2-3fps at 168mhz. (i LURB the ipaq at 236mhz runs PQ like a dream

though reletivly unstable, the 10 minutes of gaming i can get is so worth it.)
