Raspberry Pi portable gaming console

Sun Sep 15, 2013 5:38 am

Hi everyone,

I thought I'd share with you my latest project to build a portable gaming console. It has two main functions:

1) A portable console with a real joystick / buttons and a ~5 hour battery life
2) A gaming deck for TV play

The hardware is Sanwa and wired directly to the GPIOs. For the 10 inputs required for a joystick, 6 buttons and the SPI LCD you need to solder header P5 onto the board (gives an additional 4 GPIOs). Ill probably add 2 more buttons in the future using the UART pins giving a total of 12 control I/Os.

The stock RetroPie is used but the kernel is replaced so as to support the SPI LCD for portable use (fbtft).

I didnt manage to find a case I liked for it so I used two sheets of perspex with 40mm spacers. This works very well and allows you easy access for debugging / future mods

Let me know if you have any questions or want to make your own. Happy to share any details.

I guess that you could use a bigger screen?

Yes you are right :) I dont like the quality from the composite input screens though, perhaps an HDMI -> LVDS model is the way to go
