Metal Gear Solid running natively on the ESP32-S3
This project brings Metal Gear Solid, originally released for the PlayStation 1, to the XIAO ESP32-S3 Sense. The game runs directly on the ESP32-S3 with an LCD display, using the microcontroller as the actual gaming platform rather than emulating a PlayStation 1. The project explores how far the ESP32-S3 can be pushed by porting a real 3D PlayStation-era game to a tiny microcontroller. I also used Velxio, my browser-based embedded development and simulation platform, to iterate and test the firmware before flashing it to the physical XIAO ESP32-S3 Sense. The source code and technical details are available in the project article.
