October 18, 2010 // 11:22 pm - Update: Test 2 is now available, with complete details on the changes outlined HERE.

Here is what I call PS3 Acid CFW, an XMB custom firmware XML hack pack for the PlayStation 3 console.

I spend the last days in playing around with PS3 FW files and have modified some of them and hopefully unlocked nearly ALL Debug options.

I mainly have edited the RCO's and their XML's. It's phenomenal what can be done with a simple XML file.

Download: PS3 Acid CFW - XMB Custom Firmware XML Hack Pack

The Wii works on the same way, but anyway we can change the whole XMB via the XML's. It was a childs play to add some paths from one XML to another and add additional download paths for contents that before was only download able into one path. (eg PS3HDD or PS3 only games).

In my country nearly all chips that can be used to make a PSGroove are sold out. I still have some ATmega8 chips at home but I need to modify the source to get the thing running.

The LUFA software USB LIB doesn't support ATmega8 so I'm trying to use a other smaller soft USB but I will need some days more until I can compile the first hex.

Therefore, I am putting out these modified FW files for PS3 to let other guys test if you wish.

Be careful what you're doing and don't UPDATE. I tried to block every update option but as I said it's the first time and it's not sure that every thing works like it should. But together we will find it out.

• First download a PS3 FW Dump first (THIS is the one I used) so you can replace the files with the PS3 Acid CFW file linked above, and put only the folders from "PS3 Hacked FW files" on your USB stick into the dev_flash folder. Make sure to not have any additional files on it !!

• Extract the contents of dev_flash2.rar on your desktop. Use the xRegistry app (or PS3 Multi Tool) to edit the your own one and activate the debug options. I have set a bit flag but don't know if it will work in case that every reg file I have don't include one single bit flag. But as SKFU told us I have set a flag instead of a value.

• After that is done, put the xReg back on your PS3. Now insert the USB stick with our CFW and load the files with USB Firm Loader.

Let me know if it works and play around a bit, tell me what is working and what not. Currently only English and German should display ALL Debug options. Support for other languages will follow soon.

Below are a few things of what would be changed:

PS3 Debug Options activated:

• Hax_Home/PS3_Game/
• Install PKG
• Check
• Lock
• Unlock
• Chancel Purchase
• Delate
• Update via HDD
• Delate Update from HDD
• Title Store Preview (Store)
• Title Store Preview (In Game)
• Import
• Export
• Quick Sign Up
• Performance Bar
• No Memory Limit
• Quick Preview
• Owner Information
• Fake HDD Size
• CORE Dump
• Game Debug

PS3 System Hacks:

• Block Updates
• Block Online Updates
• Block Game Updates
• Unlocked Secret Debug Options
• Unlocked PSP Only (now you can copy PSP only tiles on any media)
• Unlocked Pocketstation
• Unlocked PS2
• Unlocked System Driver Pocketstation
• Unlocked System Driver PS2

I will now continue working on the ATmega8 mod and hope that I can get it small enough.

Ok thx for clarify. So we will find another way to flash cfw onto the sys. But first we have to get the ACID cfw running like we want.

to my understanding the reason for the USB loader was because of not being able to write to dev_flash, dev_flash2 I heard which would allow PS3 Acid to work.

I tried with FTP but it doesn't work. I get and error saying that it can not write on that directory (or something like this).

Sure we can write to dev_flash.

Just use FTP Server.I dont have tested it till yet but if we can modify the files from dev_flash and load them via usb then we also can write those files to the dev_flash.

Why should it not work?

Don't worry, thanks for help me. I will keep my custom sound here, who knows someday we can do that.

well then the answer is no, there is not currently a way to write to the internal dev_flash.. sorry for not understanding correctly.
