MK64 Portable 1.1
True widescreen: single-player racing is now rendered with a 16:9 field of view, so the PSP screen shows more of the track instead of a stretched 4:3 picture.
Install: unzip and drag the MK64Portable folder into PSP/GAME on your Memory Stick, then put your Mario Kart 64 (USA) ROM next to EBOOT.PBP. Existing data/ folders from 1.0 keep working; just replace EBOOT.PBP.
