🎮 Building a DIY Gaming Console Using ESP32

Retro games never get old.

As makers and embedded developers, we usually build IoT dashboards, sensor projects, automation systems, and robots. But this time I wanted to build something different:

A mini gaming console powered by ESP32.

The goal was simple:

✔ Build with low-cost components ✔ Add multiple games ✔ Use an OLED display ✔ Keep it open source ✔ Make it easy for anyone to recreate

The result is a compact DIY gaming console capable of running classic games directly from an ESP32 development board.
