i've had a similar issue before with a usb loader. try without hacks and if u still freeze, try replacing ALL of fox and falcos files on the iso with the originals, see if it still freezes. then try replacing the common5 file next with the original. our issue was that donkey kongs rel file went currupt durring the iso rip, causing it to freeze everytime he was in a match. hopefully that helps
I said I was using an original disc. I played the game without any hacks at all on Gecko and Riivolution and they both still break so its either because I'm playing an NTSC game on my PAL wii or because my disc is broken. I might have to resort to playing my PAL disc but there just isn't the codes that NTSC has.
