Custom Firmware 3.71-M33 Released!

I just s**t my pants… After much drama Team M33 has finally decided to release their new custom firmware — 3.71 M33! Get it while it’s hot folks!

Just to be clear — please make yourself aware that 1.50 kernel enabled homebrew WILL NOT WORK with 3.71 M33, yet… As mentioned below, “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)”.

3.71-M33 changes:

* 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.

Installation requirements: A fat PSP with 3.52 M33-3 or 3.52 M33-4. Previous versions of M33 won’t work, due to a bug that affects them and OE; or a PSP Slim with 3.60-M33. Instructions can be found in the always important readme.txt. Resort to our forums should you encounter problems or difficulties.

No time for chit-chat, must go install. Enjoy!

Huge props to Team M33, Dark_AleX, and everyone else involved with the development of custom firmwares.

P.S. I found this interesting: on Team M33’s site, it’s stated, “M33 == Dark_AleX.” Also, dark-alex.org now points to M33’s site. Could it be?! Yes, of course it is!

Thanks for the heads up, EvilSeph
