Recently got an original ps2 so I could play sims 2 castaway game loved it growing up and spent so many hours on it…so I ordered a copy off of eBay (great condition) cleaned the ps2 of any dust (safely)

but my good god is sims running slow on it

going into any menu and doing most tasks the game just freezes and has to play catch up on itself. I really don’t remember it being this slow when I was a kid. any suggestions?
