CFW5.00 M33 Release5.00 M33
----------

Instructions: Copy UPDATE folder /PSP/GAME/ and run.
Put the 5.00 sony update as 500.PBP in same folder, or let the program download it for you using a wifi connection.

Changes:
- 4.01 to 5.00

- Bug fix: when changing speed in xmb, and the psp turned the brightness to 0 automatically the speed was reseted to 222 again.
Note to pspstates plugin users: this plugin won't work in this firmware due to it being made
specifically for 4.01. Running it in 5.00 M33 can cause problems, wait until an update of plugin.
