There has been a stir that a PSP port for PSGroove is in development with the name "OpenPSJailbreak". PS3Hax members, madshaun1984
, have exposed "EAVPSP" as a fake, and that has no idea what he is doing. You can read and laugh at the chat logs HERE
. Apparently all EAVPSP was working on was compiling a sample from the PSPSDK and making it look like a fake GUI.
So it seems we are back to ground zero on a PSP port, but rumor has it Mathieulh is working on a PSPGroove port (no confirmation), and there may actually already be a completed PSP port in the wild.
And just as a friendly reminder, don't waste your money and donate to someone who doesn't show his progress/results first
