After the loading screen with some pictures the game stops working, popping a black screen. I have Free McBoot on my PS2 Slim 7xxx with ESR installed and I've actually used it here to boot the game. So what could have possibly gone wrong?
I booted the game again and after the loading screen it now shows an error. The error says something like "Can't read the GTA:SA disc". The game shows it for a second a couple times and then the screen goes black again.
Tío, couldn't you just make do and run it via USB on your PS2? You sure look like you're having a lot of trouble running it, and the PS2 version is admittedly one of the worst ports (Xbox had a much better port, but it's neither here nor there).
