How it works: The Wii has two modes; a wii mode that lets you play wii games and a GameCube mode that restricts the access of the wii to its wii systems and lets you play GameCube games. While in the Gamecube mode it is almost impossible to access most of the normal Wii functions, and most importantly, it is almost impossible to access any homebrew application. The rungcbackup.dol copies the gcbackup launcher to memory and changes to GameCube mode and also patches the DVD read functions in memory, to make reading DVR-r's in Gamecube mode possible. This is technically able to block your wii, but will most likely result in you not being able to play GameCube games, but this can be solved in the future when a GameCube Mios fixer/restorer is released.
Before you do this instructable you need to already have The Homebrew Channel, DVDx, Wii backup launcher 0.3 gamma with cIOS7 on your wii.
Since the process to do that is long and since someone else already posted an instructable how to do that, follow this instructable before you start to do this hack.
Note that the WII backup launcher is unable to play Gamecube backups, that's why you need Gamecube backup launcher to play Gamecube backups.
I AM NOT THE AUTHOR OF THIS PROGRAM.
Wiigator (The actually author of Gamecube backup launcher 0.1 Theta/Xi and Wii backup launcher 0.3 gamma.) has a warning for all of us.
It is prohibited to use any of the software to illegally copy games, they are intended only to create and play legal backups of games that you own. In some countries or regions it is still illegal to make copies of games
that you own, check with your local authorities if you are unsure. I cannot be held responsible for any misuse of these programs. The use of any of the above software is done so at your own risk. If you mess
something up or anything undesirable (i.e.: loss of warranty, brick, lawsuits, jail time) happens because of any of these programs, it is your own fault. USE AT YOUR OWN RISK!!!!
If you have any questions at all it's better if you ask before you start messing with your Wii.

what rate do I write data to the disc?
DVD+R can screw up the laser on the wii over a long period of time. (it still works though, but be careful)
I tried installing the WAD installation, but one thing was wrong.
"Installing Custom MIOS, please wait...
>> Installing ticket... ERROR! (ret = 2011)
[SUCCESS]: Custom MIOS installed successfully."
So I'm not sure if it's installed or not. All I can say it, I updated my Wii when I played New Super Mario Bros. Wii. So I'm not sure if that's why or not.
I'm positive I have an NTSC-U rom. Not sure if Paper Mario is compatible or not, seeing as the list was down. But anyway, I tried to run the game on the Backup runner and I got a giant green screen which restarted my Wii.
One of the three must have happened.
1. The Custom MIOS didn't install.
2. I burned the ISO wrong.
3. The game isn't compatable.
Any help, pl0x?
The error happens when you try to install an ios that relies on a trucha bug that was patched by Nintendo. You need to restore the trucha bug on your Wii console before you can install any CIOS or MIOS. Here is a good tutorial to restore the trucha bug on your Wii if you have firmware 4.0 or 4.1: sites.google.com/site/completesg/hacking-guide/trucha
Follow this tutorial ONLY if you have FIRMWARE 4.2 ON YOUR WII:
sites.google.com/site/completesg/hacking-guide/trucha-bug-4-2
After you're done restoring the trucha bug on your Wii, install the Mios again, and it should work.
But I do have another problem. This guide is confusing. I've downloaded all the WADS, the App, etc. I've gotten to the screen that says
"ISO:60
Install an IOS that accepts fakesigning"
And I click the fakesigning option.
I've done everything up to "Load IOS from SD card." and it's saying after the first time "Getting IOS12 from 257." Okay, cool. Press it again and it tells me "IOS 15 Downgrade to revision: 257 complete! IOS 12 successfully downgraded! Continue to install your fakesign accepting ISO 36? Getting IOS36 revision 3351..."
So I press "Load ISO from sd Card" and I get something like this.
"Could not open (Suchandsuch WAD).wad
Could not open (Suchandsuch WAD.wad
error reading ISO into memory.
Failed. Restarting..."
And takes me back to the homebrew channel.
I'm positive I've downloaded everything I needed from the guide. Any help again? And I'm so sorry I'm bugging you about this. -Sigh.- if you don't respond, I understand.
thank you...
But anyway. Ummm. My firmware is 4.1.
