Gamecube Problems

Hi, I was wondering if there is a tutorial or something on how to write a Gamecube Emulator. This is mainly because I can't get the method of using PSO method to get the .gcm file format. When it says connecting to the DNS server, it says ERROR 102 (the gamecube does) you may not be connected. I use Gamecube ripping server, so if I'm doing something wrong, I need a detailed tutorial that tells everything. Basically, choose one of the above you know best about.

Yeah, I guess I could use a better guide than the ones I've seen. I did manage to get it working though, but I used the new CD-ROM guide and got ISOs. Dolphin can't seem to do as much with the ISO format. That is why I'm seriously considering writing a emulator dedicated to that format.

Yeah, but I don't know how to do that. The CD-ROM method only produces ISOs as far as I know.
