ok so because no one is bothering to help me out
i have another question
has anyone else asked the same question
or put up a information topic about how to play the gamecube iso's

or do i have to buy those gamecube discs which im guessing wouldnt work with the pc

you know. I may put dumbass topics up on here but the least you could do is help... i would

Do you know what i did after posting this. I searched the forums and i helped someone out with a gamecube emulator related topic i suggested that the person tries Whinecube because dolphin wouldnt work for that person.
I had a similar problem with dolphin and i helped that person because i had experienced it myself that same day.

thanks to everyone for help
