How to Install 5.00 M33-6 Custom Firmware on your PSP

Hey fella PSP gamers out there. It’s nice to be back again. Sorry if I haven’t updated this site in 3 months. There were problems with my cheap web hosting and I’ve been busy with work. The recession on the states has affected me so I need to work my ass off to pay my mobile phone bills and other expenses..

I know this post is very much too late but it’s like obligatory to post the instructions on how to install the latest update. We’ll here it is (taken from DA’s instructions):

This update is a try to fix memory stick low speed since 3.80.

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.

Changes in 5.00 M33-5:

- A setting has been added to recovery, that, when enabled it may increase memory stick reading speed. (only on the psp, not in the pc).
By default it is disabled. If you installed 3.71 fatmsmod, do not use this setting, as its perfomance with 3.71 driver has not been tested.
Instead, reinstall 5.00 m33-4 using dc8 and update to 5.00 m33-5

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.

    Is there a way to recover the save files or “uncorrupt” them? My psp was previously 4.01 M33-2 then i upgraded it to 5.00 M33-6 for Dynasty Warriors Strikeforce.
