Dark AleX has updated his site again, releasing version 2 of the 1.50 kernel addon for the Sony PlayStation Portable Fat. This update currently works with your PSPs with CFW 3.90 M33. Here's the changelog for Dark AleX' 1.50 kernel addon version 2:

* 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! :D) Before, only the first 4 GB portion was recognized by the 1.5 kernel. Now, the theroetical limit is 4GB*512 = 2 Terabytes. ("only" 1 TB, if sony were using signed variables).

To install this update, just copy to /PSP/GAME and then run.
