A new video has been posted to a popular PSP homebrew site that appears to show a homemade version of tic-tac-toe loading on a PSP that has been upgraded to version 2.0 firmware. While the game does not actually run, the video demonstrates that it's possible to load a homebrew program from a memory stick, presumably by tricking the PSP into thinking that the program is the version 2.1 upgrade. At any rate, it's a promising start for homebrew development on the latest firmware, which, besides tighter security, contains a number of new features.
