PSP Slim's first custom firmware, by M33 (again!!)

[Hard core Rikki]

M33 official site
Custom Firmware 3.60-M33 is out (announcement)

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 applications to work in these firmwares.

Included with the release is the M33 sdk for programmers.

Installation:

The installation 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 confusion: 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 overwriting 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.


F.A.Q

Q: My homebrew doesn't work.
A: as stated above, not all homebrews work due to 1.50 kernel missing.
Wait for the programmer of that homebrew to port it to new kernels.

Q: How can i unbrick the PSP Slim?
A: if you have a semi-brick, you can restore it using recovery and flashing the corrupted files with usb flash. There is no real unbricker for PSP Slim yet, but we plan of doing one in the future using C+D Pandora Battery.

Q: is M33 gonna make a 3.60 cfw for the fat psp's?
A: The firmware as it is flashed in the slim psp's is only for psp slims. Whenever sony releases an updater, we'll support both, fat and slim psp's, but we are not gonna make a custom firmware using 3.60 slim dump, because it is not done for the fat psp. Stop listening stupid rumors of kids:
we are 103% sure that Sony will continue releasing firmware updates for all psp's.

Moreover, the 3.60 firmware was done before 3.52: the pops, for example, is a clone of the one of 3.50/3.51 , so it has nothing new for fat psp's.

Q: I liked the FW, what can I do to help M33?
A: You can contribute some money for all our members to get PSP Slims. Our paypal address is m-33@yandex.ru

good to hear that homebrew 4ever!

On a similar note, Sony rushed and released its 3.70 official firmware like its life depended on it

just like in all cases where prev firmware was dumped hacked and moded

I don't know why they keep making futile attempts to stop homebrew, if anything its a major booster to the usefulness in handhelds.

It cuts into their bottom line, the less games sold is the less profit.
If you can play hundreds if not thousands of NES, Atari 2600, C64, Genesis, Super NES, games etc, why'd you want to buy commercial games?

I'm not saying I agree 100%, but I can understand their viewpoint!

Actually the PSP slim firmware is up to vers. 371. I know, I have a PSP slim and I upgraded it to vers. 371. Also, have the component video cables and am enjoying PSP games on my 30 inch monitor.

off topic! when did you come back sxamiga?

I'm waiting to get the slim psp, only reason for me getting it is tv-out and my old psp is busted forever

[sxamiga]

Off topic! Yeloanzndevil, I've always been "around". Just silently watching and observing is all. Been busy with work and my console systems. Take care.
