Well that swapping method is a lot easier than the swap key but it unfortuantely does not solve my problem.
When I was in Mexico, a while ago, I purchased some odd ps2 dvd rip games, they were black bottom and like 5 pesos, 50 cents, each so I bought a few. And surprising they ran on my ps2 but it was only 1/3 of the actual game. I know it's a cd but I can't identify the type. So I'm guessing my ps2 only reads certain types of media?
