I am so sorry! I thought that Little Mike awnser meant just stop emulation and play it on a GC. I'm Dutch you see and I apparently didn't understand it. So I'm sorry Little Mike and Xtreme2damax.Well excuse me for it being late at night and being exhausted when I replied, I saw nothing wrong with Little Mike's post as he mentioned a workaround to fix the problem with Pokemon XD.
There is no need to be rude or use profanity, if you don't like something use the pm system to politely resolve any problems you have with a member and keep it off of the forum.
Yes Colosseum is working with Dolphin as far as I know, haven't tested it in a while to verify whether or not it works in the latest revisions. I am unsure if any other Pokemon games work.
