Yeah, that would be cool. Just want to be as sure as possible about the controllers that can be used, comparing it against the latest official release.
So my Datel controller came in and sure enough is incompatible with the latest official build of snes9xgx. Hopefully I can get it working with your build. I would try to fix it myself, but the steps in the OP are incomplete for now. Step 2 has a broken link. If anyone else has access to the mod libogc or can help me get this controller working with the app, please let me know. Otherwise, I'll just hang tight and hope that niuus can work his magic.
