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.
The preview picture was made by DeathWeasel, a fellow modder. Make sure to check his patreon page!
Downloads / ダウンロード
Full version / フルファイルバージョン
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.
