February 1, 2011 // 9:04 am - Today PlayStation 3 hacker KaKaRoToKS has announced news of PS3MFW, a PS3 Modified Firmware project!

From the official site (linked above): We have just been informed by an anonymous source that a new modified firmware-project is underway: Project PS3MFW.

There are several contributors, some of whom are well-known within the PS3 homebrew community but wish to remain anonymous. However, we were told that KaKaRoTo is playing an important role in the project.

The purpose of Project PS3MFW is the development of a customizable tool that creates modified firmware for Playstation 3 with many great features not available in current solutions. It provides a framework where each firmware modification task is an independent plugin with access to an API that facilitates the modification process. One important feature is that the project will be entirely open source, as opposed to every other MFW released to date.

The tool will be called “PS3MFW Builder”, and it will work in conjunction with several other utilities.

Project PS3MFW is an ongoing project; anyone qualified can contribute. A release of the PS3MFW Builder v0.1 is imminent.

Updates from KaKaRoToKS via Twitter: PS3MFW has ~65 customization options, the backend is robust and does a lot of checks, we tested almost every combination, on 3.15, 3.41 and 3.55 and tested it on over 15 different PS3 models, we had no bricks at all.

The "Task options" you see are just for the "clean video" task, each task has its own options that you access with the 'configure' button

FYI, in the screenshot, that "theme" option is just about the GUI theme, has nothing to do with the generated PUP.

For now the tool doesn't support 3.56, but it works and was tested on 3.15, 3.41 and 3.55. I will release more information later:

PS3MFW Builder v0.1 Features:


  • Show verbose debugging information

Thanks. But in the tutorial was mentioned that only DVD region can be changed not the Blu-ray!

that analogy is spot on rep given.

Hm, I dunno if this analogy is proper, but, if you've ever used nLite for windows and removed services and programs you didn't want, in a way this is kind of like that. Basically you are making a custom firmware tailored to your needs choosing the options that you want. Then it spits out a custom firmware with those options that you can flash your ps3 with. Basically. I'm sure other people have a much easier way to explain it.

Kind of reminds me of the android custom firmware, choose what you want in your firmware (in the kitchen) then press the bake button,this looks really cool cant wait to try it.

Is there any hope that some of these modified/custom firmwares could also have options to change (movie) Blu-ray region?
Is that even possible?

I take it this has not been released yet? I wonder what the patching of Lv1 and Lv2 does. Considering kakarotoks stance on piracy I kinda doubt that we will get peek/poke which means running backups is out of the question. So how useful this really is going to be is a big question.
