Updated: Playstation Classic Project Eris
Always shut down the console properly before removing the USB.
Project Eris is a custom firmware and modding package developed by the modding group ModMyClassic (formerly known for the BleemSync tool). It allows users to add hundreds of their own PlayStation games, modify emulation settings, install retroarch cores for other consoles (NES, SNES, Sega Genesis, Game Boy, etc.), backup save files, and even change the console’s boot menu theme. playstation classic project eris
