PSP Custom Firmware 3.80 M33 Released

[BlackKnight]

Dark_AleX / Team M33 has released the much anticipated new CFW 3.80 M33. This not only allows homebrew to use the new 3.80 kernel, but also to run games that require the new version. The interesting thing about this new CFW is that it updates purely with a Sony update EBOOT. In effect, any risk of bricking should be eliminated since you are not at any time compiling your own update. This is very good news for PSP users who may not want the hassle of creating a Pandora Battery in case of a brick.

 

3.80 M33

--------

 

Requeriments:

 

- Installation requires a PSP with 3.52 M33-3 or higher. In the future installation using

panddra battery will be released.

 

Instructions

 

- Copy the UPDATE folder into /PSP/GAME/

- Get the 3.80 sony update from somewhere, and put it in same folder, with name "380.PBP".

- Run it, the update will be done by Sony updater. At the end when you are asked to reboot the

PSP pressing X or O, do it.

 

 

Changes:

 

- HEN core: user mode can load now signchecked files from flash.

- recovery: flash1 format will create flash1 directories after format.

This could fix some flash1 issues with the previous versions.

- Network update from dark-alex.org page. By default is enabled.

You can turn it off in recovery (when off, network update will download sony updates as usual).

- Nids resolver for various kernel libraries.

 

Comments:

 

In 3.80 sony has changed (again) kernel nids. The nids resolver will resolve a lot of nids from firmwares 1.50-3.60

(traditional nids) to the ones of 3.80 kernel.

In general, 3.71 nids will NOT be resolved to 3.80 ones. However, to compatibilize 3.80 M33 with prx's programmed for 3.71,

a few very 3.71 nids that were found in some 3.71 plugins will be resolved too.

More info about what is resolved in nidsresolver_status.txt.

 

Thanks to the combination of the nids resolver and the user libraries possibility in kernel mode added back in 3.71 M33-3,

some programs that stopped working in 3.30 M33 may work again now. One of them is PimpStreamer 0.90.

 

Finally, popsloader plugin from 3.71 will not work in 3.80 M33 due to its system dependancy. A new one will be rewritten for 3.80 M33.

You need to be running 3.52 M33-2 to install. As ever there is a minor risk of BRICKING YOUR PSP, but the chances of that are reduced greatly by the lack of any opportunity to really stuff things up. The same rules apply as when installing any Sony update: keep your battery charged and the AC adapter plugged in.

 

Team M33 has also released the first patch for this firmware- 3.80 M33-2;

 

3.80 M33-2

 

Requeriments:

3.80 M33

 

Instructions: Copy UPDATE folder to /PSP/GAME folder

 

This update fixes a couple of issues.

 

- Function scePowerGetClockFrequency/scePowerGetClockFrequencyInt was not resolved properly due to a

confussion between the two nids applying to the same function. Fixed, this update is necessary

for plugins and kernel homebrew reporting psp cpu speed.

 

- PSX EBOOT.PBP that have a icon of 80x80 pixels will not be replaced by Dracula icon in savedata.

 

Explanation of icon issue:

In 3.80 pops, Sony has introduced a bug that causes a crash when the icon of the pbp is not 80x80,

like those of psstore. To resolve the issue, M33 was replacing the icon in ram by the one with Dracuala image,

what caused the side effect of ps1 save games having Dracula icon.

 

Now the behaviour in 3.80 M33-2 is to replace the icon in ram only if the one in the file is not 80x80.

This update obviously requires 3.80 M33 installed to run.

 

The final feature of the new M33 CFW versions is that by default, the XMB's 'Network Update' feature now directs to Dark_AleX's website. Cumulative updates can, in theory, be applied via this method, eliminating almost all of the risk and hassle in keeping up with CFW developments.

 

Congratulations again to 'Team M33' for continuing to make the best Custom Firmware in the PSP scene even more capable and easier to use.
