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.

    I will stick to 3.90M33 on my white-ceramic PSP slim.

    4.01M33 = too much hype and nothing new, who cares about 4.xx kernel? who cares about crappy old 1.50 kernel stuff?

    I will update when they add real DIVX support, save-states, flash player 9.x and a new webbrowser for the slim because the current webbrowser is crap.

    Alright, I just finished updating my PSP via the 3.90 M33 Network Update. It works fine! If you can’t follow simple instructions then you deserve to brick your PSP.

    Second, this is ONLY FOR THOSE USING CUSTOM FIRMWARE! You cannot put custom firmware on your psp without using a Pandora Battery, etc,.

    Let me Reiterate [[[THE ONLY WAY TO PUT CUSTOM FIRMWARE ON YOUR PSP IS BY USING A PANDORA BATTERY OR ANOTHER SUCH METHOD. THIS ONLY WORKS FOR PEOPLE WITH EXISTING CUSTOM FIRMWARE INSTALLATIONS.]]]

    make your own pandora battery (or buy one for 13 pounds on amazon) and make a magic memory stick (youtube)

    Guys again I reiterate, Use http://www.consolespot.net or http://www.psp-hacks.com
    or http://www.qj.net They have more info than this site. Plus the only reason why most emulators won’t work is that they don’t have an open-end kernal patch, meaning some of the developers didn’t think about future updates and stayed back in the primative age. If you still want to use old emulators and/or apps try out eloader. As for ps one games, they are going to work because psp’s in general have the ability to process the data that are ripped from the cd’s.

    ay peoples, i jus downloaded this a few days ago and works great, also got psptube and a emulator for the bga on it and everything works great. only question i have is, why can’t you get flash player on hacked psp’s? i already got psptube but you have to already know the page address so it’s pretty useless :(

    Ok slow down ppl. I have 3.90 m33-3 and im not in any hurry to upgrade. I jus hate the the IRshell doesn’t work on 3.90 but thats ok. I can always downgrade.
