I really need lots of help with burning a DVD+R for an iso

I need on how to burn the Simpsons Road Rage for Gamecube into an iso. I am using a DVD+R, not a DVD-R. I am using ImgBurn to burn the game into an iso. And when it was done burning, I could not find the completed iso game file. I looked in My Computer in my CD burner drive, but it was not there! Then I put my DVD+R into my DVD drive, and it said the disc was not formatted! Then it said it was corrupt and not compatable with Windows. What is it talking about? I mean this always happens after I finish burning an iso. I don't know why. I can't seem to get the completed iso file to come in either of my CD drives! So please help me on this issue please step-by-step, and tell me what I am doing wrong. Also, is what I am doing legal or illegal? That is what I am trying to figure out. You know what, maybe you can't burn iso's because it is illegal. I really don't know about this, so who knows. But you should know about this problem that I am in. So anyway, please get back to me as soon as possible and tell me what is really going on here so I can finally play my completed game isos. All right then? Thank you very much!

 

1. PCs (actually, the Windows Operating system) cannot read Wii or Gamecube discs.

2. At best, when Imgburn detects the disc, it will show status as "completed.

3. Gamecube .isos are too large to put onto CD-R. the native format is mini-DVD.

The only way to test it is to try it in the Gamecube or Wii.

I suggest that you spend some time on the Gamecube or Wii forums. This is discussed several times a week.
