5.00 M33 out now

Its only been a few days and Dark_AleX has released Custom Firmware 5.00 M33 at lightning speed.

Apart from the obvious firmware number change (see below), this update comes with a bug fix.

Bug fix: when changing speed in xmb, and the psp turned the brightness to 0 automatically the speed was reseted to 222 again.

The readme also mentions that users of the save state plug-in will have to wait for an update due to problems with compatibility.
