Innovations :
- Emulation of firmware 3.71
- VSH Menu is not longer launched using HOME key, but using SELECT now. This is to not
interfere with the XMB function of home, which is now more useful in this firmware.
- PSP Slim : umdcache was allocating memory even when homebrew was launched, wasting
memory that homebrew programs may want to use. Now umdcache module is stopped before
it can allocate any memory, only in the case homebrew is launched. Also, memory is unprotected for user memory usage by M33 core (only when homebrew is launched).
- Both version boot now from 3.XX ipl, and are independent of 1.50.
PS: The main installer will not install 1.50 kernel anymore. A 1.50 kernel addon for 3.71 M33 that will install inside 3.71 M33 will be released in a
few days (for PSP™ Fat only).
Note: Due to some changes in kernel nids by Sony, you can expect a lot of kernel plugins not working anymore.
NB: To install this update you must be in custom firmware 3.52 M33-4 on PSP™ or custom firmware 3.60 M33 on PSP™ Slim.
The battery must be charged at least to 78% and the power supply must be connected.
Place the files at the root of your Memory Stick™ then go in Game --> Memory Stick™ and launch the update while pressing on "Cross".
CAUTION: Once finished, the installer will ask you to start again, to make this action press on "X" or "O" buttons... Do not escape this stage by switching off your PSP/PSP™ or your console will be bricked.
IMPORTANT: Never touch Flash0 or Flash1 of the PSP™ Slim 3.71 M33 because that causes a systematic brick of the console !
