wii backups wont work
I usually play my wii backups using a external hard drive & sd USB loader 1.5, but the latest games won't load just get an error message saying eject disc & restart. the latest ones I have tried are Lego harry potter, new super mario bros, mario galaxy 2, I have looked for an update for the loader but there isn't one out anyone any ideas.
Switch to USBloaderGX. There's a guide for nsmb and smg2 on this site. Lego harry potter could just be a missing ios. See if the problem's fixed when you switch to GX.
