HF Patch for Koikatsu v3.1 / コイカツ！自動更新
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 content creation and gameplay improvements while still keeping the original, uncluttered feel of the game. 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.
Koikatsu can be split into two parts: character and scene creation tools (character maker and Studio), and an adventure game with story mode (it can use your custom characters, but not scenes). The preview picture was made purely in Studio. You can see a video showcasing the creation part of the game here.
HF Patch does not contain the full game, paid expansions or any other pirated content. You have to buy the game and expansions separately. The base game (Koikatu / Koikatsu Party), and by extension this patch are not suitable for minors. If you are under 18 years old you can not use this patch. The base game and this patch contain only characters of age 18 or higher. The creator of this patch is not responsible for creations of its users and prohibits any unlawful use of this software.
「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。

This version is outdated, look for a new version here
This download contains the entire HF Patch and can be used offline. You can use qBittorrent or a similar torrent client to open the magnet link.

Read before installing
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. There are also chat and sharing channels for scenes and cards!
You can see the source code here.
Note: To keep the download size reasonable, Sideloader Modpack with Studio items is not included in the download (10GB+). To download them you can use the KKManager mod updater - run it from the game launcher.
Important note, read in case of issues when downloading or installing
If you have trouble downloading by using the magnet link, try updating your torrent client or use the latest qBittorrent (it's known to work well).
Windows Defender is flagging the .exe file for some reason. If you have trouble downloading or installing the patch you can either whitelist the .exe in Defender settings (security center > virus protection > protection history) or disable Defender temporarily while you download and install the patch (remember to re-enable it afterwards!).
This often happens when a new version of HF Patch, or really any non-signed application installer is released, and stops happening after enough users mark it as not malicious. If you are unsure if the file wasn't compromised, test the .exe on virustotal.com to see if it is actually infected or not. If you see any "looks like or might be malicious" detections, this post blog post might shed some light on the situation.

hello i'm trying to download through the magnet link but he can't see it he says the file was not found
You need to paste the magnet link to the "add from link" window of your torrent client. I recommend using qBittorrent since it's known to work well. Note that I just released a new version of the patch, so this one is now outdated.
ManlyMarco, you are amazing.
I got "White Screen" every time when i try to load my save
Did you install HF Patch with default settings? If not, try reinstalling it and leave all default settings. If that doesn't help, send me your output_log file from game directory. It would be best if you posted it on the log on the Koikatsu discord server in the #help channel, you can ping me then. Or you can also PM me the log.
can i have the HF patch and Rx both installed?
Yes, there will be no issues if you install HF Patch over Rx. You probably shouldn't install Rx updaters over the patch though.
I want to download the link but i don't have money and I don't know how to use the magnet link
You can use qBittorrent to download the magnet link, just put it in the "Add from URL" window. There are plenty of tutorials on how to use magnet links online if you have issues.
Hey. I went to install the patch, but I checked and unchecked some boxes (of which I can't remember what I changed). After that, when I started up Studio, it launches into the interface, but I get a blue to pink background and I can't load any characters or maps. Same when I launch the game and try to load the Maker; it just doesn't load. Do you think there might be a reason for this?
Here's the link to the BepInEx log, by the way: https://drive.google.com/file/d/12uOytFWUK7j5fPQnpwqbaNsc3b0EgTFB/view?usp=sharing
when in the story mode H scene have an error make the breast stick together https://imgur.com/C4CVvb6
Restart your PC and install the patch again, this time with all default settings.
i install the hf patch and got this error https://imgur.com/LRAKeBZ please tell me how to fix
hey, i just realised that the subtitles are gone after installing this patch, is there a fix for this?
When installing the patch check the subtitles option. It's off by default because of the bad translation quality.
i have disabled antivirus/windows defender, but when it finish install, the Koikatu.exe not installed, in that folder just initSetting and KoikatuVR exist
Try restarting your PC and installing the HF Patch again with default settings. Make sure there are no errors during installation.
you guys i have a question when on HF3 says "Use custom Character Database" is that why i cant seem to use any character at all on the studio? like i cant select character forlders and or single characters at all
post some screenshot . i can use character card just fine . and when installing HF do use recommended installation , dont add extra checklist
Hello, If my game sometimes crashes while loading Free H, and its say Microsoft.NET Framework error. It could be the fault of Koikatsu files or more of my computer ? I have 16 GB Ram, procesor i5 -9400F and Graphics Card Gtx1650 2gb.
KK doesn't use Microsoft .NET Framework (it uses Mono instead) so it sounds like something else might be crashing. Make sure that you are not running out of RAM (keep task manager open on the resources tab to see), and try updating your system and drivers. If that doesn't help then it would be best if you asked me on discord since it's easier to talk and send log files.
so i just bought the afterschool dlc , install it with guide in the steam , then reinstall HF . then suddenly when i playing free H mode my notebook goes to sleep on its own when i played on battery even tho its fine before . does anyone else experience this ?
turns out it caused by certain character card , which is quite weird . when i do free H with her , the notebook roar weirdly for a bit then go into sleep mode , maybe something akin to self-defense mechanism . also sometimes character accessory/clothes isnt properly loaded into free roam mode , which mod to fix it ?
i change another download player it's Nailed it. THX
sorry. I got problem. When i install HF Patch v3.1-2 ,it was eorr like is https://i.imgur.com/ylfZhMG.png
Make sure your download is not corrupted. Verify downloaded files in your torrent client or try to redownload.
Hi again ManlyMarco. You solved a previous issue for me by pointing out this recent update, I was running v3.0.2. I have one more now, if you can help. Many of my custom characters' hips pop weirdly to one side in the character maker and in H scenes like their pelvises are broken. In the character creator it seems to happen randomly when adjusting some bones in the body or changing clothes, and will carry over to any character I load until I close the character maker. In H scenes, sometimes it happens right away as soon as the girl's model loads, sometimes it happens when I change or removed clothes, and lasts the whole scene. It seems to be related to the size of bones as it's worse for thiccer girls. Though I've used the extended slider range mod and new body sliders I don't think I've created anything too extreme. Any ideas?
Did you install the patch with all recommended settings? If no, try reinstalling, if yes then can you narrow down exactly which sliders cause this to happen?
will you add auto kupa like cm3d2 in there future ? kinda weird seeing it aint properly opened when inserting the thing or fingers
For now there's no plugin that adds this feature. There were some in development or planning but nothing came out of it so far.
So you wont share the links anymore for free? Thats sad news :c
well looks like the torrent one is free
How can I remove/disable KK_MobAdder v1.0? I can't find it in the BepInEx folder
You can turn it off in plugin settings, or by removing the dll in the bepinex\plugins folder.
hey dude uh utorrent doesn't recognize your magnet link
Make sure you copy the whole thing and paste it into uTorrent's Add from link box.
I cant direct donwload the patch my antivirus detect a troyan on the files :(
Check the "Important note" section I added to the post. It's a known issue and for now it's necessary to whitelist the patch or temporarily disable windows defender.
The system shows that I can't execute

My computer cannot open your EXE file for 64 bit. Is there any other solution?
Make sure that your antivirus isn't blocking the exe file from starting.
can it translate the game into chinese?
No, Chinese translations are not included. You can install them afterwards.
so found patch 2.7.1 with exe , installed it and all . how do it upgrade it to the latest ver tho ? it has no exe file at all
Check if you downloaded the whole patch, and that your antivirus didn't quarantine it for whatever reason.
Thanks so much for putting up the download links so promptly.
So i just noticed that the shadows of the characters are not showing the hair, the shadow outlines look like mannequins. Didn't notice it before, so might have been like that before the new patch. Just wanted to know if you knew of a solution? Thanks
This issue has been present since day 1, unfortunately. There were some attempts at fixing it, but nothing came out so far.
hi , new to this and downloaded the hf 3.1 , but somehow there's no exe file to run the patch . should i just dump the file to specific folder ?
Check if you downloaded the whole patch, and that your antivirus didn't quarantine it for whatever reason.
Sorry to ask, but this patch faced an issue. It stuck at SideMod Creamstar part first and unable to extract out due to the source file is corrupted, and the rest of the files are corrupted as well and unable to extract. Skipping each failed to extract file is not recommended. How should I fix this?
Sounds like your download got corrupted, go to your torrent client and make it verify the downloaded files. (Assuming you didn't remove the download from the list already. If you removed it then you might need to redownload.)
When will direct download be available?
They are available now. I'll share them with the $1 tier in a couple of days.
Will updating through KKManager do the same thing as installing this?
It will update mods but not the plugins.
the torrent magnet doesn't work for some reason or is it just me?
same here, stuck at "Metadata download created"
Should I get this if I have been keeping up to date with all the stuff you have been posting for patches/new releases? Also, kind of a tangent, but how can I turn off the ahegao thing? I can't figure it out, or even where it is, but the mouth open, tongue out like a dog panting bugs me lol.
If you updated your plugins manually then there's no need to get this. Remove bepinex\KK_Ahegao.dll
Why can't I download HF Patch for Koikatsu v3.1?
Make sure your torrent client is up to date and try restarting the download.
can I use this HF patch if i have an older patch?
Yes, you can use HF Patches no matter what you currently have installed. You don't have to do anything extra, just install it as normal.
Windows Defender says the Koikatsu HF Patch v3.1.exe is a trojan. Uuhh? EDIT: False positive...
This always happens after a new release. When more people start using it the antivirus programs stop flagging it.
