Alright, from the last post, apparently these roms dont work on emulators, bringing me to..... how do i get it on the gamecube disk, and two, how do i (in another sence of....:) gamecube uses mini disks! (i downloaded naruto clash of ninja 2)p.s. naruto gekitou ninja taisen 4?!?!?!?!?!?!?!?!?!? (aka naruto clash of ninja 4 [NOT naruto clash of ninja revolution 2]).

In order to play them on your Gamecube, you have to modify your Gamecube. Which I think involves a DVD drive and Modchip.It is easier to play them on a softmodded Wii with a Gamecube Backup loader.

ok, ill keep that in mind, ty. btw, when i said naruto gekitou ninja taisen 4, i meant is there ever going to be a downloadable rom for it, actually to add, for dolphin too, ty for answering though

I'm sure there is a copy available out there.Currently Romulation only has NTSC-U (North American) games. I don't think Seph has any plans on hosting NSTC-J games.
