I did update the project for a long time because I was improving the emulator's performance, now GameGear can run up to 70 FPS! 

But I will show in a future update with all the details. By now I want to show a port of DOOM to the microBYTE. It runs at 40~30 FPS and totally playable, even has sound. The save functionality is not fully functional but I hope to implement it soon.

Is like a tradition that DOOM must run on every electronic device with a screen.

You can see in the next video:

The initial port for ESP32 was done by Espressif, but this is a modified version for this specific device.
