For NES:

Bad Dudes (The president has been kidnapped by ninjas. Are you a bad enough dude to rescue the president?)
Battletoads
Battletoads and Double Dragon
Double Dragon 2
Double Dragon 3
Nightmare on Elm Street (kinda crappy, but has up to 4 player co-op platforming on one screen)
Ninja Crusaders (think like 2 player Ninja Gaiden)
Nintendo World Cup (great Technos soccer)
River City Ransom (this is the one you want, this is the one you want!)
Shadow of the Ninja (think like 2 player Ninja Gaiden)
Super Dodge Ball (great Technos dodge ball)
Super Spike V'Ball (great Technos v'ball)
TMNT 2: The Arcade Game
TMNT 3: The Manhanttan Project

For SNES:

Battletoads and Double Dragon
Final Fantasy 3, aka 6 (2p from the beginning, you each control a couple characters during battles, and you can change at any time, great classic RPG with great soundtrack, in case you have a really long drive)
Legend of the Mystical Ninja (platforming action with towns in between stages to buy items and train and learn info, hilarious plot)
Secret of Mana (2p adventure/RPG after you find the 2nd character)
Troddlers (2p co-op puzzler)
Super Battletoads
Super Double Dragon (if you have a short drive, this whole game's like an hour and really fun)
TMNT: Turtles in Time
Zombies Ate My Neighbors (super sweet amazing classic top-down shooter with assloads of enemies, items, weapons, and zings, full of classic movie monsters and then some, highly recommended)

For Genesis:

Sonic 2 (it's like 1 and a half players, and 2 players for the bonus rounds, I guess you could trade off Sonic? hey it was fun when I was like 8 or so)
Streets of Rage 2 (great beat 'em up with amazing soundtrack)

For N64:

Goemon's Great Adventure (same as Legend of the Mystical Ninja)
Perfect Dark (try all the challenges, I dare you)



CASE CLOSED.

And if any of those aren't fun, I'll give you your money back!

 wow thanks a lot man, and to everyone else.  That's quite a list you have there.  And to whoever said knights of the round, i don't think that came out on any consoles, but it does remind me that I also have a full MAME romset as well.  Holy crap there's probably SOOOO many sick arcade co-op beat em ups, but anyways, River City Ransom is a great game I'm glad you reminded me of it, I've beaten a lot of the games mentioned here so far, and River City Ransom I got an hour or so into, but then me and my friend never went back, can't remember why, but that's definantly a consideration.  How far do you have to get in Secret of Mana before you get the 2nd character?
