Went ahead and ordered a AT90USBKEY. Ships from my home state of Minnesota, so I am fingers crossed to grab one of these for labor day weekend to tinker around.
I am really hoping this enables region free PS2. I've got some old Pop'n and IIDX games laying around from when I had a working JPN PS2 that I have been itching to play lately.
Stupid dead laser =(
At any rate, this should be prove to be a fun project. Emulator's ahoy!
Edit: Just asked a friend if he wanted me to grab him one, and it seems like all the Teensy's and AT90USBKEY's are spoken for haha. Major sellout across every supplier I've found. The original $130 key just ended up making tons of cash for everyone selling homebrew usb controllers. Most of those places are small ma&pa type electronics hobby shops, so I couldn't be happier.
