I got it to work.
Yesterday I used DVD+RW and DVD-RW. But they didn't work.
I just bought Verbatim DVD-R ones and burned the partition.iso with IMGBurn at 8x Speed. Wario Ware Smooth Moves stutters at videos, but the gameplay is smooth.
Star Wars: TFU works smoothly everywhere. In the videos...
CIOS Patchmii Installer rev4 is in fact Waninkokos IOS rev5.
But I got the same problem. Using IMGBurn. I will now try CloneCD because I read on another forum that Wii Games on cheap DVDs burned with CloneCD are playable with the Backup Loader.
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
