This is just a hilarious mistake from when I tried to mod the Two Player Hack of SMB1. Play co-op as Mario and Luigi in random levels with strange glitches such as walking through walls. Have that reset button prepared tho. Some levels are impossible to beat due to the randomness of this mistake of a hack.

not really a hack per-se but if my memory serves me, FF9 on ps1 has natively support for 2 players (decide controller for characters in combat.) i always thought it was pretty cool since it's not really the kind of game you'd think of playing with 2 people.

I don't know about FF9, but FF IV definitely does have that option (on PS1). And there are hacks to add this to FF III: http://www.romhacking.net/hacks/1797/ and FF V: http://www.romhacking.net/hacks/2122/.

Nice to see this get some attention. I really love these hacks as well and I will create some myself too. I'll make a personal projects topic once I've made some progress.

BTW: Secret of Evermore is in the NES section.

This is a great idea. I didn't even know anyone had done a 2 player mod before, let alone a dozen or so. I'm actually curious to know what steps were taken to achieve some of these. I should investigate and think about doing one myself.

But anyone who suggests Final Fight SNES can GTFO, just play the Sega CD or arcade versions.

That's very insensitive towards the SNES gamers who really want to play Final Fight on their console in multiplayer. Not everyone is interested in playing on PC, obtaining another version or getting new hardware.

1. My PC is plugged into my TV, so it makes little difference to me.
2. Obtaining? You mean finding a second-hand physical copy? If that's the case, what use is a patch?
3. The SNES came out almost 30 years ago, I think you'll be okay getting some new hardware.

Hey, if someone else wants to do it then be my guest, but I'd rather do something more unique.

1. It's not about you(r TV), but those other gamers who like to play on an actual SNES (Classic).
2. The point is that not everyone will be interested in getting another version. They'd rather see a rom hack for the version they own. Despite its shortcomings compared some of the other versions, Final Fight SNES is well-loved.
3. Just because you have access to newer hardware doesn't mean that you have the hardware you can or want to play a certain game on.

Thanks, fixed it!

Wasn't there a two-player hack for SM64? Or was that never finished? (Or maybe I'm thinking of Galaxy?)

vergil2012 · « **Reply #9 on:** December 16, 2018, 02:58:09 pm »

So we can count this as well?

There is this: http://www.romhacking.net/forum/index.php?topic=28170

Not the kind of co-op I'd be interested in, but it's something.

NesDraug · « **Reply #14 on:** May 28, 2019, 04:20:48 am »

I added: Super Mario Bros. 3 (Player two controls a Cheep Cheep)

NesDraug · « **Reply #16 on:** July 02, 2019, 02:00:06 am »

Added Battle City Mario to the list.

I recently found this hack: http://www.romhacking.net/hacks/4336/

I haven't tried it yet, but it seems like a decent alternative multiplayer hack.

IAmCaptPlanet · « **Reply #18 on:** July 04, 2019, 11:04:57 pm »

there is a hack that lets you play Story mode in co-op splitscreen on Jet Force Gemini

http://www.romhacking.net/hacks/711/

it is a little cumbersome to set up, and is NOT just a simple patch tho

ps: i love this list, maybe co-op centered hacks should have their own searchable category, (not just "improvement")

NesDraug · « **Reply #19 on:** September 11, 2019, 01:16:13 pm »

Added the 4 player hack of Ice Climber.
