"Unless I am much mistaken, it is a japanese hack of Super MArio world, and i've already seen ppl get modded for talking about it (and other hacks) on Gamefaqs... so beware, Big Brother is watching us!"
That's ridiculous. They shouldn't mod you unless you actually tell where to get a SMW rom.

I agree entirely. SMW hacking is related to SMW and is not illegal, as we are not providing the ROM in any way, shape or form.
Brutal Mario is, yes, a Japanese hack with some insane ASM: there's a lot of strange and fun bosses from other games. It can be opened with Lunar Magic though. IIRC, the hack isn't finished yet, though Carol, the creator, has been on SMW Central from time to time.
You just wait, when Brawl comes out, they'll make tons of Nintendough.
