Weird chip and no PSx playability...
So a few years back i got a PS2, played some games, got bored with it and put it away. I got it back out a few months ago, still brand new and everything. Decided i'd get a few PSx games such as Twisted Metal (1, 2 and 3). I burned them at 8x (my burner can't go any slower). But i don't even get to the PS logo, i usually get a black screen, or a red screen that says "Please insert a playstation or playstation 2 format disc" or just a looping red screen.
My bios is ToxicBios and my chip is MarsPro (just finished putting the ps2 back together after some cleaning).
EDIT: forgot to write that its a slim, not a fat ps2. :)
