I know this is a long shot but Unreal Tournament is an old game so I was wondering if it was possible to port it over to the PSP. Epic recently released the source code(I think a new version of it) for the public so maybe someone could take a look at it and disable or edit out things like the multiplayer(unless someone figures out how to do their own wi-fi connection with the PSP) and any other unnecessary things. I know the experience won't be the same without two analogs but we can make it like games of the old days that used only one stick. Forward to go forward, backward to go backward, and right and left to look both ways so we can add map all the controls to the PSP. Here is the link to the source:
I thought I might as well tell you guys about this.
