Then, the download process. They need to look for "Guitar Hero World Tour" in WBFS format. The RRB part is tricky. RRB could be a region hack or a specific disc type. Maybe I should mention checking the file extensions and headers. Sometimes RRB discs have modified headers to bypass region locks. If the user has a region-free Wii, that's easier. If not, they might need to patch the WBFS file to change the region.
