Brawl Mario has been released! Download it here.
Two textures have also been updated. Cosmic Mario now wears different coloured power-up suits (although the base colour remains the same to avoid a dodgy face texture, a current problem with Samus). Tuxedo Mario no longer has an ear stretched across his propeller suit helmet (as seen here).

NSMB-Mods is now Mario-Mods.com, so that the site can still bring you cool mods and accept your awesome hacks for future Mario games.
Finally, I know Jose Gollardo has made a Brawl Mario mod, but this one features powerups and levels of awesome the likes of which no internet has ever seen.
