I'm having a problem when I try to play backup games that were released in 2010, like Super Mario Galaxy 2, Guitar Hero 6, PES 2011, Rock Band 3, and New Super Mario. The disc channel just says: Unable to read the disc. Gecko OS won't load it either, it shows up the following error: No dvd found. If i try to copy a backup to an usb hdd on my wii, it just won't find any dvd. I think my wii chipset is the gc2-d2c, according to its serial. I've tried downloading many modchis config discs, but they didn't work. I've tried these: wk2UsaV1.3 - Wiikey 2 "Shows up on disc channel, wii restarts when launched, boots via gecko os, says that no wiikey 2 was found." wiikey.1.99.beta.usa - Wiikey "Doesn't show up on disc channel, wii reboots when booted via gecko os" wasabi_upgrade_config_3_0 - Wasabi "wii reboots" d2pro_dvd_usa_v1.8 - D2Pro "Doesn't show up on disc channel, no dvd found by gecko os" Can anyone help me ? UPDATE : [youtube]http://www.youtube.com/watch?v=6VxK5_3xIrQ[/youtube] Sony vegas didnt render the video properly, skip to 1:23 to see the video Those yellow dvds have the following code according to imgburn: Destination Media Type: DVD-R (Disc ID: TYG02) (Speeds: 4x; 6x; 8x) My SMG2 Disc was recorded with this media, and it didnt work. EDIT: Look what I have found I'm now trying to burn an old backup (the ones that work) on that dvd and see if it works. EDIT : It didnt work, only the old backup did.
