DS and PSP aren't without their squabbles in the past, there's the fact that no matter how much you compare the two, there are certain obvious differences in approach that make it a bit of an apple to oranges scenario. That's why it's so intensely awkward to look at the screen above -- a DS emulator on the PSP. It's running a DS homebrew game, GeoWars, and running it pretty slowly at that, but still. DS on a PSP. The DeSmuME emulator was ported by Japanese homebrew developer SofiyaCat, and while we really can't imagine many DS titles that would benefit in any way from playback on the PSP, the sheer triumph over logic on display here has made us total fans of the effort.
