new here and i have some questions about the sd gecko for gamecube. I want to play some iso backups of games that i own. I know of someone willing to sell me their sd gecko. I always understood that the sd gecko doesn't do anything on the gamecube unless you have a loader disc like an Action Replay. This person is telling me that their sd gecko has all boot loader software installed and that there is no need for a disc. He says that he uses it without a disc and never needed one. Is he correct and i heard wrong? Or am i correct and he is probably lying?
