Overclock your system.

Brightness control

I was wondering if there is a way to control screen brightness. I have found this: The brightness can be changed, as pin 18 can use PWM. I have never bothered myself, but there is more info here https://github.com/notro/fbtft/wiki/Backlight Although, the mintypi screen doesn't seem to have an LED pi...

Re: GBA Emulator Help- Retropie

Hm, I still get much worse sound quality (due to slowness?) in lr-mgba vs lr-gpsp (tested minish cap and metroid fusion). Bios file is in place. Is there anything else I need to consider?

Framerate/Lag on MintyPi's SPI screen

Hi all, I am contemplating a mintypi build, but my biggest worry is the framerate of the SPI screen. I have read somewhere it is only in the 30s. Since many people have completed the mintypi build by now, I want to ask what is your experience with the framerate of the screen? (I don't have a 320x240...
