Sony PSP GPS
GPSP runs on LUAplayer 0.11 (needs 1.5 firmware, it is a loader for homebrew code) or later. On the hardware side a little circuitry is taking the input from a GPS mouse (e.g. from Garmin) and retransmits them slower to the Sony PSP. The GPSP software is reading this data and displays it on the PSP screen.
