yeah even i wanna know the same.. but spectraind is also selling at90usbkey but their service is really slow, they hardly reply to mails. you can even use kitsnspares but they sell it at double the price(rs 3k) and there is 10-15 days of shipping time.
Regarding software solutions. There is a PSP version, and a N900. What is the hardware requirement in doing PSGroove in software? I can develop, but I would guess there is a reason there is no PC/OSX software version. Does the USB hardware need to be of a certain type?
I have the AVR-USB-STK, and I have flashed it with your 8mhz HEX file and the LED fix HEX, I can get onto the backup manager and rip the games but when I attempt to play them i just get a blank screen, any idea what im doing wrong? I have checked the compatibility database and the games ive ripped definitely work, any help appreciated, thanks
