Help with FCE Ultra GX

When I launch FCE Ultra through HBC and try to boot it, I get an error saying "Invalid file size". How can I fix this?

Try reinstalling it through HBB or your PC.

does this come with the nes games if not where would an allowable place to get them?

No it doesn't come with games, and we can't tell you where to get them, you can do some research and find them.

ok then can you tell me any specific information I should be looking for ie. file type

I don't think I can tell you that either, the best thing to do is PM one of the mods, or admins and ask them if its ok to ask for that.
