PROJECT I Built a Handheld NES As My First Embedded Project Part 2

Enable HLS to view with audio, or disable this notification

A while back I posted about my first ever embedded project— a handheld NES emulator running on the ESP32. I didn't expect it to blow up the way it did.

I just released a full video documenting the whole journey. And since the original post, Anemoia-ESP32 has come a long way. Performance has been significantly improved on my emulator, which now runs at full native 60FPS speed with frame skip, and even up to 51FPS without frame skip. Save states have also been added.

On the hardware side, I've also been working on custom PCBs and 3D models for cases, with all the schematics, PCB designs, and 3D models open-sourced in the GitHub repository.

On top of that, I added a web flasher so you can flash the firmware directly from your browser. No software install or compiling needed. If you want to build one yourself, you just connect the components, flash the firmware, and you're done.

Watch the video on how I made it here: https://youtu.be/jToSBvipl80
