We are proud to present the first custom firmware for the PSP Slim, and the first custom firmware
that runs using a 3.XX IPL (3.60)
3.60 M33 for PSP Slim has all the features of 3.52 M33, except the 1.50 kernel support, as
that kernel doesn't work properly on psp slim (hardware problems, screen problems).
3.60 M33 will load homebrew from GAME, GAME150 and GAME360 directories, but all will be executed
with 3.60 kernel.
This mean that some homebrews done specifically for the 1.50 kernel cannot work on 3.60 M33.
However, the adaptation of code to 2.XX+ kernels is not difficult, and homebrew developers can
port their aplications to work in these firmwares.
Included with the release is the M33 sdk for programmers.
Instalation:
The instalation is done using pandora battery and requires a fat psp with 1.50 or
custom firmware with 1.50 support to run a installer.
However once the memory stick installation is done, you can use it in whatever psp slim without
repeating the process again.
We want to thank C+D Team for having created Pandora and having opened the path to custom ipl's,
without which this cfw wouldn't exist.
Steps:
- Create a pandora battery and a pandora memory stick using the C+D team tools.
- Run the fat psp with the pandora memory stick inserted, but with a normal battery.
Copy the directories pandora_slim and pandora_slim% to PSP/GAME or PSP/GAME150.
- Download official sony firmwares 3.40 and 3.50, and put them in pandora_slim directory
with names 340.PBP and 350.PBP.
To avoid confussion: These firmwares are used ONLY to extend the memory stick pandora kernel.
NOTHING FROM THOSE FIRMWARES WILL EVER BE FLASHED ON THE SLIM.
- Run the program. It will quickly extract some prx's overwrting some of the pandora memory stick.
-
Insert the pandora battery and the memory stick in the psp slim. It will boot. You won't see
anything on the screen, because that kernel doesn't support the slim screen, but it is OK, you
don't need a screen for the installation of 3.60 M33.
From here, you have 3 options:
- Press X to install M33. The process will last just few seconds, since the installer only
needs to install the M33 custom prx's and IPL. After the process is finished, the installer
will shutdown the psp automatically.
- Press L+R+triangle to uninstall M33 and go back to original 3.60. Note: this can't unbrick a
psp slim, it will just remove M33 ipl. There is currently no unbricker for the psp slim, but
we plan on doing one in the future.
After uninstallation, psp will be shutdown automatically.
- Press square to dump the PSP Slim nand. Watch out: you need 66 MB of free space in the
memory stick for this, otherwise your memory stick may end corrupted.
This option uses the team C+D nand dumper. When the memory stick orange led stops blinking,
the process will have finished, and you can either shutdown the psp, or use one of the two
previous options.
