https://www.dropbox.com/s/cq21p963nmsuc3j/Super%20Mario%20Bros.%20Co-Op%20-%20Glitch%20World.ips.zip?dl=1
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. :D

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. :P

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.

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

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.

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.

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")

This may not meet your criteria, since it expands upon the multiplayer capabilities already present in the game rather than adding more players: https://www.romhacking.net/hacks/414/

I've considered making a four-player Tournament Mode hack but have other projects that I'd like to finish first.

Nah, people have the rights to enjoy Final Fight in their favorite platform. It doesn't matter if it is from 30 years ago, or why would translations even exist? People should just learn japanese and new languages, under that mindset.  :thumbsup:

Besides, the SNES 2 player hack was done already (by two different programmers at almost the same time, no less), it is not finished yet. There is also the Final Fight 3 players hack for the arcade board.

Anybody know how to run "Super Mario Bros. - Two Players Hack" on Nes classic mini?
Xdelta is not working... but hacks of the hack like "Super Princess Sis - Two Drunk Princess (Two Players Hack)" works fine cause its .ips.
Same thing with "DuckTales 2 - Two Players Hack"
Thanks!

My point, that maybe got lost somewhat, is that if you want to play Final Fight with two players, the arcade and Sega CD versions are sitting there and are both arguably better than the SNES in every other respect, too. Your comparison with translations isn't entirely accurate: if a game was localised from Japanese to English, I would very much rank that as a low priority. It's not a case of saying "why would translations exist", it's a case that if you're going to go to the huge effort to translate a game, maybe do one that hasn't already been translated. Therefore, if you're going to make an effort to hack a two-player mod, maybe do one that doesn't already have an even better version available on two different platforms (and yes, a SNES classic is still an emulator, so the 'original hardware' argument doesn't work either).

Anyway, the three-player arcade mod IS a great idea, since that's unique. Honestly, people can hack whatever the hell they want, there's no need to get annoyed about my opinion. :D
