I mentioned in topic too.I burned many ps2 games with using the same method so i don’t know what’s the problem.Any help would be appreciated I burned it three times but my ps2 couldn't read it :/ I merged all of the parts and it became an iso file (3.76 gb) So i burned it with alcohol but it hasn't worked. Any ideas ? I changed iso file's name before burning but i don't think that's the problem.
I tried two times with alcohol %120 at 2x speed and one time with dvddecrypter at 4x speed.
Answer #1
1- Are you using the same brand of DVD to burn this game, as you did the successfully burned PS2 games ?
2- Have you tried burning something else – maybe your burner is the problem.
