Yakuza 0 Co-op Test Build
Added 2025-09-10 18:51:07 +0000 UTCHere it is! The mod is largely untested other than a few action sequences and battles, so bugs are to be expected! I have also not tried it in GOG (but i hope it works), i hope i did not forget to include any file...
If you have any questions or anything, don't hesitate to let me know!
IMPORTANT INFO
Latest SRMM is REQUIRED!
Please check the mod settings ini file at least once to ensure everything is configured to your liking! (mods/Y0Coop/settings.ini and mods/Y0Coop/Player1Settings)
Please save often to minimize loss of progress should the mod crash/freeze!
Enabling Steam Input is heavily recommended!
You can use Parsec or Steam Remote Play to play the mod online.
INSTALLATION
Open SRMM, press "Install mod" button and choose the rar file you just downloaded.
Ensure OELib is version 0.11, installed from Libraries tab in SRMM.
Ensure your antivirus is not doing any false positives and removing mod files.
Should you have questions or issues, don't hesitate to let me know.
INPUT
This mod works best with Xinput controllers (aka gamepads and xbox controllers) for PlayStation controllers, you may need to enable Steam Input which should convert the controller to a Xinput one or use DS4Windows to do it manually.
If the game is not taking your input, try enabling AlternativeInput on mod settings. Steam Input must be disabled for AlternativeInput to work!
Parsec should ideally register it as a Xinput controller, To do this:
Settings > Host > Ensure "Virtual Gamepad Type" is Xbox 360
GAMEPLAY & MOD COMPATIBILITY
Moveset mods should fully be compatible with the mod.
I would probably uninstall Legend Fix while using this mod, because the mod has its own (and better) implementation of it.
Pressing start controller key on player 2 will teleport them to player 1.
Pressing back/select on player 2 will respawn them instead of just teleporting, useful for if player 2 breaks
UPGRADES
Pressing Shift+O in the pause menu will toggle upgrading player 2. You should be able to buy their upgrades once you open the upgrades menu itself.
TROUBLESHOOTING
When you are experiencing crashes or major bugs, please send me the log file located at srmm-libs\ae8ee30b-f8f7-4b12-92a9-19093a1190f7\OELib\log.txt it can help me determine what could be causing it
KNOWN ISSUES
Semi rarely performing a heat action may freeze the game requiring restart, unfortunately nothing i can do about that
Some sound effects missing from player 2 styles (will be fixed later)
Player 2 changing the encounter theme on style switch sometimes (dunno how to fix yet)
Current implementation of legend style switching prevents players from equipping weapons on styles other than legend if its unlocked (for example, if you unlock dragon of dojima style , you cannot equip knuckles on Rush style etc...)
Comments
I think so, it's not showing up for me either.

2025-09-13 00:15:16 +0000 UTCIs the file missing?

2025-09-12 23:32:43 +0000 UTCThis could mean that the controller is not being recognized as a xinput controller.

2025-09-11 10:31:03 +0000 UTCI had the same issue, when I change something in the settings.ini, my keyboard and controller doesn't work, I can only pause the intro. But the solution that work for me is to restart the pc and then the game work perfectly and I can play with my two controllers, unfortunately I need to do that every time I change something in the settings.ini

2025-09-11 10:24:25 +0000 UTCSo the mod works, it does pick up my inputs and all, but sadly everytime I use steam remote play it just does the same bug where no one can control any inputs it, it worked for me locally with controller and keyboard, but the moment I get a connection through remote play, the whole controls just don't work including keyboard. Really found it weird, still will try and tinker to see if it's possibly my controller drivers issue.

2025-09-11 04:37:47 +0000 UTCThank you Jhrino, once again hope this doesn't come off as rude but do you have any rough idea of when the full on release will be? October November and such? Thanks fella

2025-09-10 23:57:48 +0000 UTCThanks for the upload. Weirdly, when I enable the mod (with all the libraries, fresh install of Y0) my controller and keyboard do not work at all. So I am stuck in the opening movie. Only thing that works is my escape key to pause the cinematic but, nothing else works. Gonna mess around. Turning off the mod makes it work as normal. Edit1 - Unplugging controller before launching Y0 frees up my keyboard and the game works fine with 1 input, however the moment I plug in input 2 (controller), the keyboard stops working again and the controller doesn't work. Escape is the only button that works. Will update tomorrow after random testing and maybe reinstalling mod

2025-09-10 22:48:59 +0000 UTCThe game crashes upon entering a fight outside Climax Battles, it shows an error about Y5Lib and OOE error
WarHelmetCombine
2025-09-10 22:48:31 +0000 UTCother than the already mentioned input issues with non xbox controllers, it seems upgrades don't retroactively apply to player 2 (tested in both climax battles and a lategame savefile) like how they did in 5. we also tested the finale, and for some reason trying to teleport during dialogue sequences in the long battle both restarts the entire sequence and breaks the input for both kb and controller

2025-09-10 21:49:17 +0000 UTCim not sure if i will implement AI at the moment, i will consider my options
Jhrino
2025-09-10 21:30:05 +0000 UTCI assume AI is not implemented at this time, but is that planned like you did for Yakuza 5?
SnaikerSDM
2025-09-10 21:26:59 +0000 UTCSounds like some weird input shenanigans going on, probably not converting the playstation controller to a xbox one properly
Jhrino
2025-09-10 20:08:26 +0000 UTCDoesn't work properly with Steam Input enabled for me, some key inputs don't even work after unplugging a controller (PS5, PS4, XBOX) I have to disable Steam Input and only use a Xbox controller for the mod to work normally.

2025-09-10 20:06:49 +0000 UTCcan't even navigate main menu?
Jhrino
2025-09-10 19:42:28 +0000 UTCI have encountered an issue where running the game with the mod active disables all inputs from my keyboard and my controller. I have steam input on and it doesn't seem like my computer has removed any files.

2025-09-10 19:31:57 +0000 UTCThat is not possible yet, you must press the keyboard combination for the time being.
Jhrino
2025-09-10 18:54:06 +0000 UTCAre we able to configure how to switch upgrades to player 2 from gamepad?
