Projects like OpenMC use an ESP32 to emulate a PSX memory card. Its Wi-Fi capabilities allow users to upload and manage save files via a web interface, effectively providing "infinite" storage.

Developing a PSX ESP requires calculating "World-to-Screen" transformations. This involves taking 3D world coordinates from the game's memory and using the View Matrix (camera orientation) to map them onto the 2D screen. 4. Current Challenges

While ESP32 hardware mods are generally seen as positive upgrades, software ESP remains controversial. Nostalgic Indulgences

The ESP32 is a low-cost, powerful microcontroller with built-in Wi-Fi and Bluetooth, making it a favorite for modernizing the PSX.
