So my PS2 has the matrix mod and I'm not sure about OPL. Whenever I play a game, it runs smoothly, but when a cutscene comes, it freezes and it takes several seconds to come back only to keep freezing and unfreezing again and again. The game I've been playing is Yakuza, and this lagging makes it nearly unplayable. Does anyone know how I can fix this? (I do not play via USB by the way, I use CD)
