PS3 Firmware 3.42 blocks the PSGroove and PSJailbreak USB dongles from working.

So if you want to keep playing backed-up games, do not update.

more info.

PSgroove has been released to the public as an opened source code. It allows the PS3 (fat and slim) to run homebrew apps and play backup games. Gamers who pre-ordered the PSjailbreak device have already canceled their order when the source code was released yesterday, knowing that you can make your own PSjailbreak device for cheaper. You will need a USB programmer with any of these chipsets:

• AT90USB162
• AT90USB646
• AT90USB647
• AT90USB1286
• AT90USB1287
• ATMEGA32U4

and maybe more.

UPDATE: It has been confirmed that ATAVRXPLAIN also works. In stock and available at digi-key and farnell. PSGroove intructions for ATAVRXPLAIN.

Blackcat USB programmers will work as well as AT90USBKEY. Most of these are sold out everywhere. They cost around $20-$35.

You must load the device with the PSgroove code, you can download it here.

I've had my DualShock3 controller for less than 4 months and I've noticed the right analog stick have been rough. When you rotate all the way in circles, it feels not so smooth and it bothers me while playing games like Super Stardust HD, which requires much use of the right stick. I think this game was the cause of it being rough. I checked under the right stick and can see scrape marks and plastic dust. It had been chewed into by the edges while you rotate. I simply blew air onto it to get rid of the loose plastic and sprayed 1 time of WD-40 right under the stick and immediately notice extreme smoothness when rotating. It's smoother than a brand new controller. It's amazingly "liquidy" smooth. I sprayed onto the left stick also, and 3 more of my controllers. Solution works perfect!
