I made a Gameboy zero almost 2 years ago and it was rough for a first attempt. I have worked on that one to make something different that may not be what most would expect.

First the original first attempt. completely analog buttons and a 2.4" TFT. No Audio.

TINKERBOY OS For The Win.

The TFT uses GPIO18 for the Screen function, might be why I Don't get Audio. I'll take what I learned here and use it for further projects. (I currently have several in the works)

Thank you TinkerBoy, i will give it a try and see how it goes.

Does yours already have the PWM set up on the GPIO 18?

Thank you Moosepr, i forgot all about the clone function, that got me going the correct route.

do i create the file under retrogame, /boot, or home/Pi?

Working on another gameboy zero with the BW screen. trying to install the GPIO option. Followed the How to guide and since i am using retropie 4.3 it doesn't have Adafruit-Retrogame on it and when i try to use the curl command to get it, the file displays the code but doesn't actually download the p...

Apparently 4.3 doesn't have an Adafruit-Retrogame directory. any other suggestions on how i can get the directory added so i can add the GPIO file into one.

power supply went out on this now and also my other project i had started. fun times.

I do manage to get a crackle when the GBZ is turned on so i'm getting something to the Speakers.

Managed to crash it after adding PWM code in to it and had to start over, it wouldn't boot up or load the display.
