Hey. I'm sort of a noob but i downloaded gta2800's tekken 3 and for the most part it works pretty well, but when I play arcade mode and beat it, the game screen turns black and i cant do anything. Anyway to fix this? Im running 3.03 OE-C btw.

No, dont upgrade to 3.40oe-a because it isnt fully hackable. I got the same psx iso. I think the problem is that whoever uploaded it ripped out movies so the iso was smaller. But after u beat arcade and when u see the black screen, u gotta wait to go bak to the menu yeah? Or does it just go black and crash?

I think you should be happ with the fact you could download the game and play it at all.
I brought the game and have no problems with it.
You should be happy with what u got, download another version or buy the game
