Loocking for a specific game control board

[geekgamer]

Hi.

I'd like to use a PI to make a portable console like a game boy advance or a psp.
A PI + 5"LCD + 10000 Mah power bank with solar charge + laptop speakers + homebrew case with 3d printer...

I searched a lot, but only found "arcade boards" with 12 buttons + 1 joystick (4 contacts).
What I want is a board able to support:
-2 analog joysticks (potentiometers)
-1 control pad (4 contacts)
-12 buttons

Of course I could take the board of a standard USB pc controler, but it would not be such a clean work.

Any link, name or reference would be very helpful.

Thanks a lot :-)

There is the a-pac board, but 39$ is too expensive and the second controller will be useless.
