For the games that use an utopia boot disc you also have to use the same method for use with Chankast. All games are original in some way or another. Some may use shrunk audio, video or use other tricks to fit a 80 minutes cd recordable. Because they use an utopia boot disc does not mean that they are not original. It's just another external trick to make the game boot. The selfbootable discs just use another exploit of the machine so that it's fooled to think that it's using a real disc.
