The PlayStation 2 (PS2) remains one of the most popular consoles for retro gaming enthusiasts. For users with a Matrix Infinity modchip installed, the primary method for loading games is via Open PS2 Loader (OPL). While the modchip allows the console to read burned discs, OPL allows users to load games from a hard drive, significantly reducing load times and preserving the laser.
