* NID resolver: Fixed scePowerGetCpuClockFrequency issue. This is the same bug that happened in 3.80 M33-1, it won’t happen again ??

Dark_AleX has released PSP custom firmware 4.01 M33. This new custom firmware edition from DAX brings 4.01 kernel support and features from firmware 4.01, multi language recovery support and many minor bug fixes. Custom Firmware 4.01 M33 does not have a XMB recovery menu or savestate support at this stage, this will follow in future updates possibly 4.01 M33-1 or 4.01 M33-2.

4.01 M33 can be downloaded and updated on 3.80 M33 upwards using the network update feature or use the download links provided.

* Extract the archive. * Copy included UPDATE folder to X:/PSP/GAME

* Place the official firmware 4.01 update EBOOT, named as 401.PBP, in the newly created UPDATE folder
* Begin installation from the Game menu.

Sony have released PSP Firmware 4.01, this minor update includes the following:

• Display of search results under Internet Search has been improved for certain languages.
• Playback of video content under Video has been improved for certain file types.

Playback has been improved for certain file types? Does this mean DivX ?

Dark_AleX has updated his blog in regards to all the questions he is receiving about 4.00 M33 custom firmware. Rather than rephrase it, here’s what Dark_AleX has to say about 4.00 M33:

Just a little update. Watching how many people were asking for 4.00m33, it’s interesting to make somethings clear.

Due to the lack of updates from sony (features), this new cfw will implement new changes that will make easier to work on the future ones, within some internal tools.

You’d have probably noticed some features of this new cfw that were told on french forums, but, to tell the truth, neither the savestates or the recovery on XMB or etc would at 100% probability be implemented at once (maybe later on m33-2, … etc)

Even though, recovery will be translated to spanish and you will be able to translate it to any other language without hex editing.

To sum up, main changes will come for compatibility and internal issues (with some functions to make life easier to the shells creators, launchment of an utility to compress prx’s and pbp’s, etc.)

It will be likely be done by the end of this week.

So there you have it, its likely it will be out by the end of the week.

Update: 4.01 M33 has been released.

Good news for those that are awaiting for news on 4.00 M33. Mathieulh has commented on a couple of great new features that are going to be introduced in this up and coming M33 custom firmware.

Custom Firmware 4.00 M33 will feature an XMB recovery mode, which will allow access to the recovery menu from within the PSP main menu / XMB. A feature which was first introduced in 3.95 GEN, now will be a part of M33 firmware. The second new and more exciting feature to be added is native savestate support. Users can save and load their progress at any given time while playing a UMD game. Much like what many common PSP emulators have. However it has not been decided yet if it will be part of the released 4.00 M33 firmware or released as an add-on / Plug-in.

Still no release date yet on 4.00 M33 but its looking good. Savestate support will be very handy indeed.

• Update: 4.01 M33 has been released.

OldPrisoneR has been working on a new build for FuSA and that there is now added support for PS1 games. So soon you’ll be able to enjoy that PS1 game in full screen.

OldPrisoneR is on his vacation at present time, however he continues work on FuSa SD.
I’ve just received message from him…he is unstoppable!
He managed to add PS1 (POPS) games support for FuSa SD!
OldPrisoneR has also said that at this moment he is working on new SpeeD BoosteR, which must avoid any slowdown.

Great news indeed, however it won’t be released intill OldPrisoneRis back from vaction in July. Oh and if you didn’t know FuSa, adds support for fullscreen TV out on any PSP slim TV out cable.

Judging from the comments made on PSPGen (The GEN/Miriam Custom Firmware homepage) Version 4.00 GEN might not see the light of day as a public release. Although a beta version of 4.00 Gen has been completed by Miriam, Team GEN might keep this release internal as they are aware that Dark_AleX and team M33 and busy on thier own custom firmware - 4.00 M33 due to be released soon.

Miriam / Team GEN - Translated from French:

“The concept of Custom firmware GEN was to show that there is an alternative to Dark_Alex but never try to take his place. If he returns to the runway, the need for the line 4.00 GEN does not feel right.”

So either way users wanting to run homebrew with the features of Firmware 4.00 will have their custom firmware soon be it 4.00 M33 or 4.00 GEN. Its nice to see they are not directly competing, racing to see who will get 4.00 custom firmware out first.

So what do you think? 4.00 Gen should be unreleased? Let the Team M33 release their work first?

Team M33 have returned and are busy working on PSP Custom Firmware 4.00 M33. The master himself Dark_AleX is working on this now. Its also reported that there will be a brand new recovery menu in 4.00 M33, no other new features to be added at this stage other than what was included in the official Firmware 4.00 update. The release date? No date set yet, however 4.00 M33 custom firmware will be released soon…

Update: 4.01 M33 has been released.

PSP Firmware 4.00 has been decrypted and by the same team that brought us PSP Custom Firmware 3.95 GEN. So what does this mean to us? Well this opens the door up now for either 4.00 GEN or M33 custom firmware. Decrypting the firmware is the first step towards Custom Firmware enlightenment.

From the PSPGen website, translated from French:

“Many PRX’s were changed such that pops popsman, npdrm, np9660, mlnbridge, sysmem, umdcache, sysconf, video, etc.. Good news, it will not pose too many problems for future adaptations for a Custom firmware.

Please note that the NIDS do not seem to have been changed but the file pafmini has yet changed what can possibly ask for the concerns of some compatibility issues.

This suggests that a custom Firmware based on firmware 4.00 will be rapidly introduced

PSP Firmware 4.00 has been released by Sony. This slighty lack lustre release features the new internet search feature via google and the ability to control the view speed of videos on the memory stick! Wow I hear you say…. Not much of a release for a x.00 step up in Firmware.

* [Internet Search"] has been added as a feature under [Network"].

* You can now change viewing speed during video playback by pressing the UP/DOWN buttons. Use this feature if you want to watch a video quickly, or if you want to slow down playback and listen to the dialogue carefully.
