PSP Downgrade/UPRADE/Unbrick Filinvest Two Area, Batasan Hills Area

3.90 M33-3 changes:

• March33 noumd driver compatibiilty has increased to support games like Coded Arms, Patapon, Harvest Moon Innocent Life and probably others affected by same errors.

1.50 Kernel Addon v2 changes:

• TA086: when being in 4th brightness level and recovering from sleep mode, the display was black. Fixed.
• Added support in the 1.50 kernel for memory sticks greater than 4 GB. (I finally got my 8GB card!) Before, only the first 4 GB portion was recognized by the 1.5 kernel. Now, the theoretical limit is 4GB*512 = 2 Terabytes. (”only” 1 TB, if Sony were using signed variables).

Update: Patch For Loading 3.71 FATMS Driver On 3.80, 3.90 M33 v2

Version 2 changes: fix a bug that prevented access to the music, picture and video folders.

Homebrew developer Dark_AleX has released a patch that allows users to load the original 3.71 fatms driver on 3.80 and 3.90 M33 series firmware, which if installed, will resolve this issue.

Note that while this patch will increase memory stick read speed, the 3.71 fatms driver will require use of more kernel memory.

Following the release of custom firmware 3.80 and 3.90 M33, some users experienced lag when loading compressed files and plugins from the memory stick, an issue that did not exist in previous firmware releases.
