Well, the Speedrun.com rules say "Do not post pirated commercially owned games or ROMs or links to those games or ROMs anywhere on the site." So I don't think anyone could really help you with that.

Not a mod myself, but I highly doubt the mods would go through the trouble of verifying a patch for such a niche problem. Also, why can't you just insert your cartridge into your 3DS and play the game as intended?

Mupen64PlusNext is a fork of Mupen64Plus. It isn't exactly the same, so it's probably not allowed.
