You might want to go ahead and make an ISO even if it is too big to burn onto a cd you can save the iso in a root directory. You can then boot up using your regular 3.7cd using the cheat code bootfrom=/mnt/hdaX/*.iso. That way you can make sure that your game remaster runs before you spend a lot more time on getting the size of the ISO down. I tried to do the same thing one time and the game just froze up.
