Wii 4.3u Help

Hello, people from WiiHacks. I would like help with my Wii. I recently Softmodded my Wii in order to make Gecko Codes work with Gamecube games. I also accidentally broke one of my old GC games, Pokemon XD. I downloaded the ISO and burnt it on a DVD-R "memorex" brand. Problem is, it still doesnt read it with Gamecube Backup Launcher 0.3. Any help would be appreciated, thanks.

PS: (I'm using IOS 249 rev 65535(?))

Let me get this straight......
You need to get gecko working so you can cheat on your downloaded game?

Is that correct?
