"Some games are not supported yet by 3DNes. It's just that."
Then I would suggest getting on that before doing anything else. People are going to want to play their favorite games with this software and if their favorite game isn't supported they're not going to want to play, regardless of quality.
"I repeat again 3dn files are not rom files. They are just 3d patch file for a specific game. You must open your own rom file to run your game."
Yeah. I know. I'm not a moron.
