This is teh illegal... Compagnies can still sue you even if the games aren't being produced anymore.
You're spreading AND encouraging people to break the law and download ROMs to play online.
Contrare,
This ISN'T ILLEGAL, if you OWN the catridge, and I own about 70 catridges for SNES, and about 150 NES catridges, and about 20 SEGA catridges.
If you own the CATRIDGE it isn't ILLEGAL,
And yea' playin' NES Gauntlet with a friend pwnz, and MM:S is.. well... odd at best...
Anyways,
I'll help yall out with a short list of multi-player SNES games.
Super Mario [Already mentioned]
SoM [Also Mentioned -.-]
Battle Toads [Decent Beat'em up, fun to turn friendly "fire" on and beat the hell out of your friends

]
Sun Set Riders [Fun shoot'em up, but... some of the bosses are INSANELY hard]
Contra: Alien Wars? [Pretty sure thats the name, one of my favorite games of all time... maybe not all time, but.. one of my favorites of the old cons0lez]
Goof Troop [....heh..]
Mortal Kombat I-III [Do I have to say anything?]
Killer Instinct [Another pimp fighter]
Donkey Kong Country [

]
And finally...
Zombies Ate my Neighbors [OMFGOFMGOFMGOFMG If you've never played this game... you should be shot and hung. Anyways, DL it, IT PWNS!! This is prolly my second fave multi-player game on SNES]
Hope that helps,
That should last yall for a little while,
The only downside with the SNES is, I don't believe it had many multiplayer rpg's, which = @#$%
Anyways.
Peace.
Oh Yea',
If you need any help with another list just tell me, That was a sloppy list.. -.-
