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 finally modeled and 3d printed the new HDD cages I need in order to build my 2nd NAS. Original ones don't fit the mounting holes on the hdds I'm using. Been sitting on this project for over 2 years smfh
Also another 70TB going in the front mount drive bays of this server. 182tb raw, going to probably use a zfs RAID-Z3 for 3 parity disks, so 140TB usable
I could claw back 14tb by only doing 2 parity disks but I feel like with 13 disks in the RAID I'd be kind of pushing my luck on rebuild time if I encounter a disk failure
