I've recently acquired a Nexus 4 (loving it so far), and downloaded PPSSPP to play Sword Art Online - Infinity Moment and some other games, I also got DraStic for DS games and FPse for PSX games. I've seen a review and looked at Amazon, but I've found no gamepads with R2 and L2 buttons. I'd really like a gamepad with these for FPse and PPSSPP. A Bluetooth one. Any recommendations? Thanks in advance. PS. I know it's possible to connect a PS3 gamepad via Bluetooth, but since I don't own a PS3 I'd rather not buy one. I also read in the review I mentioned that using Bluetooth "significantly reduce the responsiveness of the controls".
