Changes in 5.00 M33-6:

- Fixed a bug that made unbootable psp without memory stick or with a bad one.

The included file fat_comparison.html contains a comparison of perfomance between the 5.00 fat driver, the 3.71 one, and the 5.00 one with the speed up hack during the read of an iso.

The test was done on the game Valkyrie Profile in cso format in march33 mode. Other games, modes and applications different than iso reading showed similar results.

Instructions: Copy UPDATE folder /PSP/GAME/ and run.

If you come from a version prior to 5.00 M33, put sony update as 500.PBP in same folder, or let the program download it for you using a wifi connection.
