The resolution modes ARE off. In an attempt to get the fastest possible renderer (which i was able to do) I used direct framebuffer access as opposed to pvr rendering. The attempt i made was to have aspect ratios which respect the original hardware, not necessarily how it would look on a tv.

i accidentally said 256x240 previously, when the actual resolution is 256x256. the display mode is currently 320x240, which accounts for the cutoff.

Full versions will run at 640x480 with stretching and respect towards the original aspect ratio.
