Hello all. I have had two Wii's since launch and both were chipped shortly after modchips became available. One has a WiiKey the other a Cyclowiz. I lent the Wiikey version to a friend and kept the other for myself. I haven't touch my system since late 2009 and I have recently tried to play some backups. The issue is that everything seems to be hit or miss. If I am lucky enough to have a backup boot at some point there will be a disc error. Most older games play fine using the modchip. Currently my main issue is my friend updated the system I lent him to 4.2U, I managed to put all the necessary CIOS files back on, HBC, and d2x files that should allow me to play games. However, games like 007, Mario Kart and some others I recently acquired don't boot at all and an older game, Zack and Wiki, that works via Cyclowiz boots then fails telling me to check my disc. My question is: what am I doing wrong? It doesn't make sense that a system that is both soft and hardware modded can't play backups. I would prefer not to go the USB loader route, I have a DVD-R, +R and RWs laying around and the fact that so far Neogamma disc loader seems to be pretty crappy and I wouldn't be surprised if the USB loader works similarly. Any advice is welcome. Thanks.
