Please be very specific when you say PSP buttons, what is the features that make them great, pics would help.
I am thinking that I can make this gripper with side grabbing horns which would simplify printing to one piece.
I am not really a gamer so I actually need all the input I can get from people who have actually played portable game systems. The closest I came to portable gaming was a old B&W gameboy with a 2 1/2 inch screen.
The whole idea is to make a superior and printable slip on gaming system, if it turns out to be really great I might adapt it to a bluetooth kb for other phones.
