3.71 M33

Custom PSP Firmware (CFW) 3.71-M33 for PSP Slim and Lite and PSP fat.
Requirements:
A PSP Slim with 3.60 M33. Or 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
Details:
Adds the ability to change CPU speed, Play PS1 games, play Homebrew games and apps, load legal ISO backups, load CSO’s (Compressed ISO files) and run emulators etc.
Change Log:
- 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.Download: (all files are required)
Instructions:
See Readme.txt inside M33 zip.

- Copy the program to /PSP/GAME/UPDATE
- If you have 1.50 addon, make sure you have the kernel of game folder configured to 3.71, or the
program will not even start.
what after? and whats the 1.50 addon?
answer back plz

I hav a psp slim and lite with cf 3.71 but i cant access the psp network without updating, is it safe to just psp update to 3.73 as prompted in games on my psp?
October 4th, 2008 at 2:20 am
OK, I have the CFW on my PSP Slim. And I have made back-ups of my UMDs. I’ve searched this site and can’t find an answer; how do you play the UMD back-ups? They are in the form of an ISO, is there another program that I need to make them readable from the memory stick? Thanks a lot for this site, it really is awesome! ^_^
