I don't know if there's already a topic for this, but you guys need to get the #XXXX roms like demos and Tingle's Balloon Fight... just a suggestion. I found Tingle, but the download is really slow and this is the best rom site with the best download times.
It's a game released only to club nintendo members. There's a public game of it, tingle's Balloon Fight is just a slightly modified version.
