Content

A patch for Koikatu! and Koikatsu Party with all free updates, fan-made English translations and essential mods. It will allow you to load all character cards and scenes and give you countless gameplay improvements while still keeping the original, uncluttered feel of the game.

HF Patch does not contain the full game, paid expansions or any other pirated content. You have to buy the game and expansions separately.

All content is tested and fixed (or removed) as needed before each update, providing a stable platform for further modding. HF Patch can also repair many common issues, try it if you have issues.

「コイカツ」のための無料アップデートと必要な改造すべてを含むパッチ。それはほとんどあらゆる取付けを更新し、修理できる。ゲームや有料の拡張は含まれていません。あなたはゲームと拡張を別々に購入しなければなりません。

Downloads / ダウンロード

This version is outdated, look for a new version here

Direct download: https://mega.nz/#F!UNcBFCxb!Mv34WxOQzexpQ0fi3Y0WiA

Downloading via torrent is recommended. The patch is larger than the standard mega download limit, so you will have to wait to finish downloading (unless you have an account). Torrent is also much less likely to become corrupted and can be easily restarted.

WARNING: This release has some known issues. After installing HF Patch, follow these instructions:

Update to BepisPlugins r13 and the latest Resource Redirector or AutoTranslator (download either XUnity.AutoTranslator-BepIn-5x-4.7.0 or XUnity.ResourceRedirector-BepIn-5x-1.1.0).

Update MoreAccessories (replace the old version inside the BepInEx\plugins folder). 

Remove KKUS.dll if you have Koikatu Party.

Before installing check this installation guide and FAQ. It was made for the Steam release (Koikatsu Party) but most of it applies to the Japanese release as well.

If you need any help, check the wiki, visit the Koikatsu Discord server and ask in the #help channel, or ask in comments under this post.

Patcher changes / 変更  

Consolidated game patches and translations into single options.

Improved how patches and translations are installed - cleaner installation folder afterwards and fixed collisions with official KK Party translations.

Fixed "Access denied" errors under some circumstances, preventing proper installation (explorer is now restarted during installation).

Fixed KKVMD custom config not being set correctly in some circumstances.

Remove KoikatuVR if it's installed in KK Party (install the KK Party VR addon instead).

Launchers are now named the same as the original lanuchers in KK and KKP, launchers with the wrong name are removed now.

Remove output logs and similar files that aren't necessary anymore.

Removed Hongfire link (RIP).

Thanks for the update！But are you sure the torrent link is correct? I cannot open it…

ManlyMarco

Yes, it's correct. If your torrent client can't load it you can get the torrent file from the mega folder.

TheEnt

Thank you. I'll try again.

Tahuti

Keep up the good work. I do have to say that antivirus -really- does not like the way the installer works.

ManlyMarco

Sadly not much I can do about it with the current setup, some AVs love flagging the patches.

Elvy

Thanks a lot for the patch. But sorry to disturb you, but i have an issu. When i launch one of my save, and clic and next to lauch the day, i have a white screen with the song and loading picture. I can't load the school.

CS

Hey, would it be possible for you or someone else in the modding community to update, rewrite or port from ai girl the high heels mod? Also not related but to avoid making more posts is it possible to turn off the motion blur in ai girl? it's rather annoying.

ManlyMarco

We have porting heelz and pushup in mind, but currently don't have any time frame for when it will happen. Check settings, try disabling more AA, if all fails open Main Camera object in runtime editor and turn off the effects you don't like.

ManlyMarco

Currently, there's a bug with how mods are loaded if you've had hardmods installed before. This is likely the cause, you can wait for a fix or you can fix it by removing the hardmod files from your abdata folder, check output_log for messages about unity3d files that failed to load. Alternatively you could make a clean installation of the game so that there are no 3rd party files inside your abdata folder.

Wrexort

is strange. i download previous patchers and all work fine. i only use this patcher this time, no other mods but all character heads invisible? i try patching many times and nothing work. disable antivirus, no mods, just missing faces everything else fine. I can return to 2.9 and faces are back

ManlyMarco

There is a known issue where if you had hardmods installed before their remaining files that aren't cleaned up will cause this sort of issues. You can install previous hf patch to go back and wait for the next version, or if you know what to look for you can manually remove the hardmod files.

2026-09-05 04:00 some eyes have error in load, then if in the previus update is ok and i go back tho these the new mods will be erase or will be ok?

TeleFlix

Hello, after installing the patch all I see after select "next" from the bedroom is a blank screen. I'm using the BetterRepack and Kplug. I'm assuming the BetterRepack has the hard mods you were referring to in the post. If that's the case, then how do I fix it? Would overwriting with the previous version of the patch work?

Frederica Bernkastel

I installed this patch and now I can't change back hair on male or female characters and half of them are losing the back of their hair. I tried everything and it still happens.

Dragon RNG

Thank you very much for the update. but I have some problems ... as some characters do not load part of the hair, the eyes, and since I have updated the game it does not go fast gives me performance drops 37 - 60 fps counting. I'm not fast as in the 2.9 update this in the H scenes and the rest is a problem. Anyway hopefully it will be solved soon, thank you very much for taking your time and updating the game. Greetings and hopefully have a solution.

Elvy

[Error : Unity Log] NullReferenceException: Object reference not set to an instance of an object Stack trace: ChaControl+c__IteratorB.MoveNext () UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) This is the error message i get in debug mode. Thanks for your answer.

Elvy

[Error : Unity Log] NullReferenceException: Object reference not set to an instance of an object Stack trace: ChaControl+ChangeClothesBraAsync c__IteratorB.MoveNext () UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress)

ManlyMarco

Check my responses to others with issues, the ones with two links to updated plugins.

Dragon RNG

I just did what you told me all my version is JP the problem of hair and eyes that does not load is already solved only the only thing is the performance still gives something low when I am in a scene or in H. Now it goes from 40 - 60 fps I mean I also have the kplug 2.0 also in 2.10. If you know anything else it can be tell me when you can. Thank you very much for answering and solving these problems.

Dragon RNG

Nothing I have done too and still follows those downturns. I don't know what it can be but nothing to wait for updates and can be solved in the future. Thank you very much for your directions until very much encouragement for your next version!.

RasmusH47

I can't select stuff from the accessory menu because of MaterialEditor. Now it's much harder for me to fix.

TeleFlix

Updating the two plugins didn't seem to fix the issue. For now, I've re-extracted the BetterRePack and moved over my character and save data, so I am basically where I was before I installed the patch. I still have the old patched game file if you want me to try anything else.

UnknownKill

I have an off topic question. For your plugin kk_ahegao, where do you find the eye id and etc?

ManlyMarco

Go to character maker and look at right side of the screen, there's an eye selector. The ID here matches the ID in the config, same with others I believe.

2026-09-05 04:00 I just got the DLC but the translations are all weird for the new additions. All the old content is the normal English, but the new stuff pops up as Japanese first before changing to a pretty bad translation. Is this the way it is? or did I mess up?
2019-11-26 03:54

RenjiXIII .

I have a problem where in Character creator, the values of my characters attributes are not changing when I the arrows for the finer details, so I've had to resort to manually putting in values.

ManlyMarco

The DLC is in Japanese only, it's being machine translated as it loads.

ManlyMarco

Did you update the two mentioned plugins and removed KKUS?

RenjiXIII .

All of them go in the BepInEx file correct?

ManlyMarco

Yes, you have to replace the existing dll files. They are somewhere in the bepinex\plugins subfolder.

murilo correia

After I installed the patch I can no longer choose the map, when I enter the map screen I can not select what I want and I can not leave the selection screen, I am limited to '' My Room ''. Anyone else with this problem and could help me?

ManlyMarco

Did you follow the steps to update the two plugins and remove KKUS.dll below the download links?

du532

Hello ManlyMarco, Thanks for working on this patch. Is there a way for me to turn off the translation?

du532

Never mind, I found the option in the installation page and deselected it : )

murilo correia

Yes I follow the steps, was to have any new map in this patch? for me there is one more in the selection screen, but the picture is all blank and you can't know what it is, it may even be one that I already had, but I don't remember and, I think that's what may be bugging my game.

murilo correia

That's right, I just checked here, I'm missing some maps, the ones that came in the last patch, the beach, etc. Maybe I may have missed or unchecked a box when installing?

Brad

Hi，I follow the install step and also follow the issue instructions, but i can't get into the story mod. Both start new one or load old one can't, it stock at the white screen.

ManlyMarco

Are you running KK or KK Party? Did you try starting with only the default male character added?

Brad

KK Party. I try starting with only the default male character added. But still stock at white screen. KK party still running, didn't turn into no responding.

Brad

The loading word didn't show either, all screen is white, music still playing. Only H Scenes and concert work normally.

ManlyMarco

Send your output_log.txt file from game directory after trying to load into the game and closing the game.

RIKLWORKS (edited)

2026-09-05 04:00 When I run the .exe to install the patch, it brings up an error prompt saying the program can't run on my PC. This occurs no matter the directory I run it from or if I run it as an admin or not, and on my Windows 10 PC, at that. Any way around this that you know of?
2019-11-30 05:18

ManlyMarco

Make sure your download isn't corrupted. If you downloaded through a torrent then check file integrity in your torrent client. Just to be sure, the game itself does run fine, right? If the files are good then tell me what exactly the error says.

ManlyMarco

Make sure your patch files are not corrupted. If the game has no mods on it, check if it's downloaded correctly as well. If everything looks correct I would suspect something about the system itself.

StonedMedusa

Hi, First I want to thank you for all the amazing work you do on these patches. But I seem to be having a problem... My previous character cards loaded just fine but I can't seem to get outfit data to work at all. New or old, I'll put old ones in the proper folder but they wont show up also when I try making new outfits the save files disappear when I exit the client. So not entirely game breaking but annoying! I installed the new patches and removed the KKUS.dll files but no luck, any idea on other fixes? Thank you for your time and Thank you again for these amazing patches!

Brad

I didn't join the parton, is there any other way I can send you the file ?

StonedMedusa

That worked!! Thank you so much!

Drago_28

Hi there i did everything but when i build class i have 25 girls in 2-1 but other classes have only 5 desks i have two dlc installed in correct order.I don't remember having this problem on my first instalation this happened after second clean reinstall.

Brad

OK, I sent it on help channel and tag you, please check it. Thank you ^^

ManlyMarco

In class rooster click the maximize seats toggle in top right, it's also at the bottom of the settings.

Drago_28

Nothing happens when i select 99 in options or during class build still 5 desks in other classes.

ManlyMarco

The 99 option doesn't change the seat count. You have to turn on the maximize class registration toggle next to it.

Drago_28

don't have that option anywhere i don't know why.

ManlyMarco

Sounds like the afterschool dlc isn't installed properly then. Try reinstalling it and then hf patch.

murilo correia

Hi, I installed Bepis Plugins r13 here and it solved my problem with the maps, but my girls got bugged, without some mods, clothes and even a cat stuck to the head. and when I delete BepisPlugins r13 everything is back to normal, but the maps get bugged again. Any ideas on how to solve?

ManlyMarco

Did you follow installation instructions for BepisPlugins r13? You have to update both bepinex and resource redirector.

Drago_28

tried several times and still nothing :( i don't know whats wrong

Drago_28

Ok managed to fix this all i had to do was launch the game before instaling hf patch i have 25 desks in all classes.But i'm little worried if afterschool is installed properly since i still don't have maximize class registration toggle in options.

ManlyMarco

That's indeed weird, you could check your output_log for hints but it might be necessary to just do a clean reinstall if you want to fix this.

Drago_28

tried several clean reinstalls desks are working.Got notification about dlc added to game but no new options in menu about filling desks should just ignore this since game is working fine?

ManlyMarco

I guess if it works then there's no reason not to ignore it. It's weird how other parts of it seem to work. In case the new dating system doesn't work you'll know the reason at least.

Drago_28

did few tests and new dating system is working fine so i guess only fill seats is broken, weird but at least game is working fine :P

Twistjewel

Keep getting the issue where the game hangs up when going to new day. Updated all the plugins listed in the top post but keep getting this error. [Error : Unity Log] NullReferenceException: Object reference not set to an instance of an object Stack trace: ChaControl+c__Iterator8.MoveNext () UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) any ideas?

ManlyMarco

Can you PM me on discord? A few people seem to have this issue while modders can't reproduce it to fix it.

Vincent Fan

Marco, I can not load any previous save or start new story mode after apply the patch. I read through all comment above and no solution worked, the load button just don't work. what do you think I can do to fix it?

ManlyMarco

Did you let it remove all old mods? Try reinstalling hf patch and follow the further install instructions in the post. If that doesn't help then send me your output_log.txt after trying to load the game.

Vincent Fan

No worries, I got a fresh new game package with Bepinex 5 then installed the patch then every thing works...

Blevk

how do i download via torrent

ManlyMarco

Use a torrent client like qBittorrent

Blevk

oh thanks

Terminus

Thanks for the update but I'm having a problem where nothing will show up when I click on the plugin/mod settings button other than a blank screen. Any idea how to fix this?

ManlyMarco

Can you show exactly what happens? Send your output_log.txt also.

Terminus

Never mind I managed to fix it by doing a clean install of the patch and game again. Thanks.

ManlyMarco

Can you send the save file in which it happens? Save just before the date so it starts when I click next day. You can send it in a PM to keep it private. The saves are inside userdata/save.

ShepirotCloud

Excuse me, in the previous patch, where you create a character, in the "pose" option there were several animations as well as changing clothes, simulating a fall etc, after I install this patch they are gone, could you tell me where I can get those animations back? Sorry for the inconvenience.

ManlyMarco

They were removed in maker because the pose menu took too long to load. You can restore them by getting the add pose mod from here https://mega.nz/#F!upYGBTAZ!S1lMalC33LYEditk7GwzgQ?HlIzXCzR You have to remove [DeathWeasel][KK]Character Maker Poses v1.0.zipmod when doing this or you will have duplicate poses and possibly other issues.

TeleFlix

Hello, sorry for not responding. I've been away from my desktop cause of the holidays, I just wanted to let you that your 'small update' solved my problem. I made a copy of my koikatsu folder that was just the better repack and installed HF Patch for Koikatsu v2.10. Afterwards I installed the slideloader mod you linked and the last mod you linked and everything seems to be working fine. Thanks for the help!

sharktangent

Hey! I'm having an issue in the character creator where when I click load/save/delete clothing data, nothing shows up. This goes for both the clothing data I have from this version and earlier versions. I've installed the updates to the files you mentioned above, and deleted KKUS. My clothing data is showing up in the coordinates folder, as well as in game and in studio, just not in the character creator.

ManlyMarco

Update the KK_BrowserFolders plugin.

LilKirbyFan03

im playing koikatsu party and when i load the next day in story mode. i keep getting this in the developer log : [Error : Unity Log] NullReferenceException: Object reference not set to an instance of an object Stack trace: ChaControl+c__Iterator8.MoveNext () UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) i have KKUS removed and Updated moreaccessories. is there a way i can fix this?

KodeShikou

I seem to be having a unique problem so far, not sure if it's my old system that's on the verge of death, or a incomplete download that's tweaking things out. Once I've selected all the things and it's preparing to install, once it's about to start it closes my explorer.exe process and freezes the installer and makes it unresponsive. Anyone report a problem like that? Or should I delete and download the HF patch and try again?

ManlyMarco

It's normal. Just wait, take a tea break if you need to. It can take some time on slow drives.

KodeShikou

Ok. Had never had that happen before on any of the older patches so glad to know it's not that bad.

Light Christia

Okay so I think I have everything ready, whats next. Do I just put everything in one folder, and when I tried running th HF patch it told to reinstall the game or verify it I uninstalled it and im installing it again will tht wrk

Light Christia

I need help, it wont let me download, its either telling me to reinstall the game or verify game files on steam cuz there are missing game files

ManlyMarco

Redownload the game from a good source and do a fresh install. Either your download is corrupted or the files are dodgy.

William JCM

So, I installed the patch (default install) on Koikatsu Party, applied the fix from the known issues section, launched the game, but all the tabs in the settings menu are blank. EDIT: this is on a fresh install of the game.

ManlyMarco

Are you sure you removed KKUS and updated bepisplugins and resource redirector? If yes send your output_log.txt file from game directory.

William JCM

Welp... I just launched the game for the n-th time, and now it works, even though I haven't changed anything. Sorry to have disturbed you. 😅

Frosteeze

I'm trying to download through the magnet link, but it seems to be stuck? My qBitTorrent client can't read it at all

Frosteeze

Nevermind, it's just really slow reading it. Just had to be patient :)

Tamamo Vitch

SO i have a bit of a dillema. I downloaded and isntalled the HF patch, without DLC, but now I'm in possesion of said DLC. How would I go about making the DLC work?

ManlyMarco

Open it in 7zip and browse until you find the setup folders, then copy their contents into your game directory, replacing files when asked (it'll be obvious when you find the right files). After you are done reinstall hf patch and follow the post-install instructions in the post again.

RenjiXIII .

I have another problem, my outfits don't appear on the Outfit list submenu

ManlyMarco

Update the KK_BrowserFolders plugin.

Katsalia

After updating the game and doing the performance fixes, if I play the game in fullscreen it's incredibly blurry and the graphics seem to drop in quality? Also the browse folder sidebar is hyper zoomed in and almost unreadable. I assume this is just a setting I need to change somewhere but I have no clue where to look.

ManlyMarco

Start with launcher and select the correct resolution for your screen.

Katsalia

I feel so stupid! I didn't realize that changing the resolution mattered if I was putting it into fullscreen mode, thank you for that!

Azsalyn

Is there a way for us to upload modded characters?

ManlyMarco

You can't upload modded characters to original uploader or you'll get blacklisted. There has been some work on a new custom card uploader, but it's not ready yet. It's better to share your cards on the koikatsu discord server anyways https://universalhentai.com

Prince Heru

So I have a problem, so I can't change any of the clothing or accessories for whatever reason, the little window that supposed to pop up to allow me to select different items doesn't show and others doesn't change to other selected items, does anyone know whats going on?

ManlyMarco

Follow instructions in the post after installing hf patch, something is most likely outdated and crashing.

Gemis037

I'm new to this game. Where do I place the files to make the patch work?

ManlyMarco

Download all files and run the .exe from anywhere.

Brad

Hi, I follow the fix update steps on the discord, and fix successfully. But my original game language is Traditional Chinese, after update it turn into English, and it's a very strange English. Can teach me how to change to Traditional Chinese ?

ManlyMarco

When installing the patch you have to turn off English translations. You can switch to Chinese by starting the initial settings launcher and selecting language at the bottom.

Brad

Yes, when I install patch, I had turned off English translations. And I also switch to Chinese by starting the initial settings launcher. But after installed I can't play story mode, so I followed the discord pin chat to download patch to fix the game. When I finish installed the fix patches, my game language change into English. Maybe is the fix patch (XUnity.AutoTranslator) that I install cause this problem ?

ManlyMarco

XUnity.AutoTranslator will translate the game to English by default. Try to open the launcher and select the correct language again. If that doesn't work, remove BepInEx\plugins\XUnity.AutoTranslator

Brad

OK, I remove the XUnity.AutoTranslator, and it's work. Thx

Ikaros1985

I can no longer select Tops and Bottoms options in the character creation portion. As in when I click on a icon for a top, nothing happens. The icon doesn't get selected. Also the Tops and Bottoms doesn't show the name of the current clothing the character is wearing, it stays blank. Also, I can click on bras and other options but when I select a piece, my character doesn't change into that piece.

Bigyeetpete

Hi! I just have two questions: I would like to try and download the "full" version of the update, but im very inexperienced when it comes to Torrenting and magnet links. Could you perhaps explain how and where I could download it? Secondly, do I just have to drag the new files over the Koitatsu party folder to update it, or is there some other steps involved? Thanks

ManlyMarco

Make sure you get the 3.0.2 version, this one is outdated. You can use a torrent client like qBittorrent or uTorrent to download the magnet link, just paste it into the client's `File > Add link` menu.
