Putting psx games onto dvd is much harder than ps2 cd-based games,and some psx games cannot be put onto dvd as they have cd checks in other area`s of the game then the usuall spots and dvd scan 3.6 or 3.7 couldn`t find,the most psx games i have heard of on a dvd is 3 and even at 3 there is a slim success rate if 3 differant games were used as the ones this guy used in his tutorial.
There was a member here at the site trying to get psx games onto a dvd and he never did get it to work after countless tries using the tutorial that this guy had were he got 3 games to work on dvd. I was going to try also but i never started as other people were having a lot of problems doing this so it does have a low success rate,but 1 game has a good success rate buut then you are wasting a lot of space on the dvd which isn`t worth it then. Hope info helps
