Interesting. Now, there is a video showing the PSGroove or better yet the patched version of it, CJPC. He does not mention which USB board he use, but the video is really an inspirational for some as he shows the Backup Manager running. Though, i have no idea what is BlackcatUSB and the fact that most USB microcontrollers that work for PSGroove are out of stock . Now, waiting for my PS3 console to be exploited soon with other alternatives..maybe with PSP?
Update: After researching the net, i can guess that he is using AT90USB162 or Teeny 1.0 (Not sure). More + to those USB boards. I wonder if there is any in my local area.
Update:The Part 2 of the video showing PS3 console with the games.
