8cm cdrs have a capacity of like 200-250 mb. the gc cds have a capacity of 1.5 gb. thats approximetely 6-7 times bigger. this is the same with cdrs and dvds, the dvd is 6-7 times bigger than a normal cd. so the GC games are probably mini dvds. you would need a DVD rom or writer which allows 8cm cdrs to actually read the game.
when the time comes to write the disk than your are even more stuck than before.
