just get the file superdump 1.3.dol place it in a folder named superdump, then place the super dump folder in to the apps folder. your apps folder should be at the root of your sd card.
For the noobies like my self who read these forums with people dumping games and burning them no problem but not being 100% clear how they did it, here is how i did it, step by step.
Its best to use a 8gb sd card for this and mine is formatted to fat32.
So once superdumper is in your apps folder, turn on your wii, insert your sd card and go in to homebrew channel. locate superdumper and load it. Once loaded, leave it how it is, making sure its set to sd card. when you load superdumper your dvd split size should be just over 3gb. click on A till you get insert disc. put game in you want to dump and press A. Now leave it to do its thing, should take about 15mins.
Now to copy it to pc. (im the administrator on my pc so if you can do the same on yours? it helps)
Take out sd card, load it in your pc. whe you open it you will see 2 bin files like for example RSWP_0 and RWSP_1 both are bin files, remove the underscore so it RWSP0 and RWSP1. Now copy these to the root of your C or D drive on your pc.
On your pc click start, run then type cmd and as most of you all know a command prompt window comes up. If you are using the C drive type cd c:\ then press enter and you will get this c:\
If you are using D drive type cd d:\ then enter and you get this D:\
Now you are ready to put in your command to convert your bins to iso.
Now type in front on c:\copy /b RWSP0.bin + RWSP1.bin (then the name of the game ending with .iso like this
c:\copy /b RWSP0.bin + RWSP1.bin mario.iso or if on D drive
d:\copy /b RWSP0.bin + RWSP1.bin mario.iso
you will get a flashing underscore type thing like you do when you are about to type somthing. leave it be and when finished it will say file1 copied.
all done now you are ready to brick block it then burn it to dvd.
