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

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.

ESP cheats read the game’s process memory to display hidden information, such as drawing "bounding boxes" around enemies through walls (wallhacks) or showing real-time health and distance data.

In a software context, ESP refers to a type of visual overlay cheat most common in modern emulators like DuckStation .
