So the first USB we bought to load our wii backups was bought on impulse. After checking the GBA Temp compatibility guide because of loading/transfer issues, we found out it was one that was reported to not work properly. So we scoured through the GBA Temp compatibility list and got the Kingston 64gb from that list. We followed the recommendation to format it with WBFS manager but this one seems to be doing worse than the one before. After a LOT of messing around with IOS' and loaders we managed to get a single game on the USB to start (all others would just display a black channel screen). But after getting past the channel screen that game will always black screen. The furthest we ever got was Monster Hunter Tri checking system memory. Before anyone recommends using the Softmod any wii guide to check we have the most up to date IOS' etc or Modmii. We used both. Still can't get the games on this new USB to boot properly. (I posted this in the wrong section before but I have already reported that myself so hopefully the Mods will delete it).
