Dark_Alex has updated his M33 custom firmware for Playstation Portable.

Changes:

– Speed selected for umd/iso was not properly locked in some new games that used scePower_EBD177D6 instead of scePowerSetClockFrequency to change speed.
– UMD/ISO speed settings now apply to PSN games too.
– Fixed libupdown.prx connecting to dark-alex.org instead of sony when npsignin_plugin checks for a new version and m33 update is enabled.
– Iso file descriptor was not closed in driver deletion
– Added a shutdown command to vshmenu.
