Ok, so I've set up a fat32 drive that ran RE4 and my 2 GameCube games perfectly, but up until now I haven't added any other Wii games, then I impulsively decided to put New super Mario bros. on my drive manually (not using Wii backup manager) but I used WBM for RE4 due to its size, now RE4 no longer shows in USB loader GX, yet New Sup does.
