big dvd disks
 

ive heard of a method that you click in the slot of the gba adaptor below the gc a dvd drive so you can play large dvd disks

big dvd discs cant fit inside the gamecube unless u remove its plastic cover.

i think he means adding an external dvd-rom drive through the gba player port

there are so meny rumors about the gamecube why to nerds like to make up stuff
maybe some stuck to the top of this forum called rumer controll might help

so it dosnt acsist to your idear ?
