I read how to use make-multiv3, and then wanted to shrink my games, so I found GCM Utility (v.5 - is there a newer version, and should I get it?). GCM Utility seems to have an option to "Generate Multiboot ISO". Will that give the same result at make-multiv3? It seems that this would be easier to use, since it has a GUI. Could someone clear this up for me? Also, do all GCN games work shrunk and used in this manner? Or only some?
