That's cool, unless it means the game will be gimped.

Doubtful. It likely just wasn't that big in the first place. I mean, how big is NSMBWii's ISO?

Edit: a quick hitup of isohunt shows New Super Mario Bros Wii clocking in at roughly 360 MB, so it wouldn't be that crazy even with only the 2 GB memory card that comes with 3DS.

Damn. Size shouldn't be a problem then.
