Big, huge, gigantic news! The great Dark_AleX, responsible for all the custom firmwares available for the PSP who claimed to have gone into retirement, is back under the name of M33 releasing a brand new custom firmware for both PSP Fat and Slim! The new firmware is barely out of the gate and is already fully hacked.

3.71 M33 by M33=Dark_AleX

Changes in 3.71 M33:

- Now uses 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).
Developer, for a sample of how to use the extra memory, see the extra ram sample of the M33 sdk.

- Both version boot now from 3.XX ipl, and are independent of 1.50.

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 fat only)

Note: due to some changes in kernel nids by Sony, you can expect a lot of kernel plugins not working anymore.
Programmers: refer to the sdk readme for details.

It’s nice to see the PSP hacking community is still alive and well.

You will need the official 3.71 firmware and the M33 installer. To install you will need a PSP Fat with 3.52 M33-3 or 3.52 M33-4 or a PSP Slim with 3.60 M33. Visit the Official M33 website for more details and previous M33 releases if you need them to meet the requirements for 3.71.

EDIT: Because of complaints that I ripped off the previous image from PSPSlimHacks.com I took my own picture of the PSP itself.

You could be one of the lucky 77,777 to own one of the Limited Edition Crisis Core PSPs pictured at the top if you run like the wind, before the stock runs out, to Play-Asia.
