burning a GC game into a mini DVD disc and making it work?

I bought mine at www.foundmy.com.

After a couple weeks of playing with this, it works flawlessly. I burn backups to the mini-DVDs I bought with the XenoGC, and they play just fine. No pot adjustments were required. All I did was solder the small $14 XenoGC board to the bottom of my GameCube's DVD drive, and put the case back together. I've burned 8 games or so thus far and they all work with no problems at all.

The Duo Q is also a board that works well. I actually found the install of the XenoGC a little tough to align -- an install with wires would be easier.

 

I recommend the XenoGC over the DuoQ. The DuoQ's just a ripoff of the XenoGC anyway.

Also, you can install the XenoGC with wires if you like, just make sure you use a high guage (really small wire) and connect everything properly. Some people have even installed power switches on them to enable homebrew compatibility.

Oh, and most importantly, use high quality media. Cheap stuff will only hurt you the long run, so get Ritek mini DVD-Rs. Get them off Newegg if you're in the US.
