Before you ask, its not a disk problem. I've burned my ISO's at 2x with ImgBurn onto Memorex DVD-R's. And its not a brand problem, because these disks used to run my gamecube backups just fine. But now, after updating to 4.2, it no longer works. I've installed cIOS38r17 and installed cMIOS v8 through rev3. I use USB Loader GX for Wii games, which works fine. failed to read dvd 263 error 0x3023a00 No disk I'm on Gamecube Backup launcher 0.2. I apologize if I sound pushy or pissed off, but the reason for this is that nowhere on the internet is a straight answer for this problem, only noob questions like" Is the booktype set to DVD-ROM" and advice like "lower you burning speed". So if someone could help me out, I would really appreciate it.
