There has been members and including myself that have tried with no success to put multible psx games onto a dvd, one psx game has a more higher success rate then putting on more than one game,as some games have these hidden cd checks. It`s entirely up to you if you want to try it but it`s pretty tough to get it to work. Good luck!
Very low success rate on putiing psx games onto a dvd,as some games do not work off dvd due to hidden cd checks in the lba table which dvdscsan or C.M.P. (console media patcher) will not find and patch.
