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。

Dave

silly question i used to have the diary but after updating i have lost it is there anything i can do to get it back

ManlyMarco

That sounds like a koikplugins feature. To get it back you have to manually reinstall koikplugins by closely following its installation manual.

Dave

ok ty i am trying to find it now

Dave

i cant seem to find it any more or i cant remember where i got it from is there any chance i can ask you where i can find it please

ManlyMarco

It's available on katarsys's patreon for supporters. There are free versions floating around as well.

Dave

i cant find it i am reverting back to the old version untill i can find it

ManlyMarco

koikplugins was never included in HF Patch, downgrading will not bring it back.

Dave

i have a back up of my game i always make a backup before i update

ManlyMarco

Where did you keep these? It shouldn't touch your files in the UserData folder. What version of the game do you have, Japanese or Party? You can use something like recuva to get the deleted files back. Do this as quickly as possible and avoid writing anything to that partition until you're done. https://www.ccleaner.com/recuva

Dovoli

it was the Japanese one but it was an all-in-one type deal. The strange thing is that when I was the patch again it left them untouched as you said it should. I used the tool but sadly i couldn't recover anything. Honestly it's my fault for not backing up my files properly.

ManlyMarco

Copy the full magner link into your torrent client. It usually goes into File>Open URL/magnet

Juha Linna

for VR perf bug. Remove KK_BecomeTrap.dll from BepInEx folder. This causting spiking CPU load or lock framerate to 60

ManlyMarco

Are you sure it's KK_BecomeTrap? It shouldn't do anything. Can you send your vr output_log.txt with BecomeTrap causing these spikes?

Grenot Guillaume

Thanks for your help... it's been for years I use torrents, but I didn't know that was possible to do this...

Juha Linna

After removing only that dll it started to work. Was playing around with KK_*.dll files and checking what is effecting there. I found git repo for that and I may look what it's doing. Edit: Little digging around. In hook call + coroutine MapChangeCo. Is there player type of gameobject in VR?

ManlyMarco

No idea. Can you try running the VR module with the dll and check the output log for exceptions?

Juha Linna

Tried to use dnSpy but got f-secure angry and after disabling it, mono.dll just crashed. Checked logs and there wasn't any error messaged for becometrap.dll.

Hi English and Steam Version ?

ManlyMarco

Hi, what do you mean? Steam version is in English, yes.

beeboy

Hey, i have patch 2.0 only, i have to dl patch 2.1 until 2.8, to avoid loose content? Or possible to dl patch 2.8 directly? By the way mega link to patch 2.1 at 2.4 seems dead.

beeboy

Thanks, but i had a message telling me that i miss " the Koitaku! AS - After School Extension (12/21 2018 Winter Paid DLC)" with 4 new personnalities, 3P ( i assume threesome)" so i download Personnality Pack and After school pack. Now, i just have to copy/past folders on my game, before use the last patch ??

Sonny Zuvich

There is a bug i found with the clothes which seem to disappear making the girls sometimes nude while talking to them...it never happened before this new update. or is it a mod that does this that randomly takes there clothes off?

limierr

Hello, i was just wondering how work the cheats tools ? After have download the game on steam, i install the patch , i try to use "f12" to trigger the console but it didn't appear i just receive the developper console. Is there others step to activate it ?

ManlyMarco

Yes, you need to install the expansions before the latest patch.

ManlyMarco

In plugin settings disable the "preserve clothes state" setting.

ManlyMarco

Try pressing the pause key or go to plugin settings and change the hotkey. Seach for "cheat" to find the setting.

limierr

I try the pause key but it didn't works (maybe between the switch qwerty and azerty ...), i pass to another hotkey and it works. thanks.

beeboy

Thanks all seems to work since i have a tutorial about DLC Afterschool when i launch game. See u

[RV]-Nobunaga

Hello there, nice to see it keeps update, thanks as always~ and is this compatible to all paid dlc right now?

ManlyMarco

Yes, it's compatible with all DLC but Koikatsu Party is still not compatible with darkness and yoyaku (and likely never will be).

Anonymous

When I install Yoyaku and Darkness, shouldn't I be seeing the change in logo? Also, will i be able to install Darkness after updating to 2.8 now?

Melodic Oak

The exe to install the HF patch triggers a few flags when run through Virustotal, and by some local protective services as well. This makes me a tad nervous, especially considering the debacle with that FlashbangZ guy that packed some viruses in with his modpacks a while back. Is this patch indeed safe? And how do I know it's safe? Thanks!

ManlyMarco

These days any non-trivial exe will get flagged by something unless you sign it, and even then it might get flagged until the AV company checks it themselves. Make sure you are only downloading from links here or on github. The patch is clean, but instead of taking my word for it ask on the Koikatsu / IS discord servers if it's safe.

ManlyMarco

There is no change in logo for yoyaku or darkness. After installing the updates you have to run the latest hf patch again.

Braxsis

Hopping some day there will be a facial hair mod for male characters creation. Nothing to drastic.

ManlyMarco

There is one goatee accessory and some people are using the 3d pubic hair accessory, or just normal hair accessories for longer beards. If you want to, you can make your own beard accessories pretty easily, if you're interested ask in the modding channels on the discord server.

Braxsis

Question! in h mode with a girl while playing the storey my MC is shown as a solid blue figure same with hands during caressing is there a way to show my MC.

Guillermo Solano

Hello! Great work! Since installing the patch does not load some of the most recent character cards. why does that happen?

ManlyMarco

Sorry for the slow reply, press F1 for settings and turn off the single color male mode. You can do it with a hotkey too, press F2 for a list of them.

ManlyMarco

It's probably because they contain mods that were made after HF Patch came out. You can update your mods automatically in KK Manager, I posted it recently.

John Doe

Hi, I'm having a problem with my character. In cutscenes he looks fine but in the free roam he is missing his hair and the back of his head.

ManlyMarco

Go to settings and make sure that all accessories are set to show in school mode. If that doesn't help, go to plugin settings and turn on high poly mode (it will increase resource usage so you might need to reduce the character limit).

John Doe

You are a lifesaver, thanks!

先生 何

我是萌新,请问这个可以可以添加steam评论里说的剧情模式吗?

ManlyMarco

Yes, it unlocks story mode in the steam release. Make sure to install the latest version of hf patch, not this one.

Ryan Cheng

Hi, I would like which update can select language at Initial settings? As I wish select Chinese instead of English. Thank you very much

先生 何

最新版本在哪里?我是萌新,有Q群可以交流一下吗?

ManlyMarco

Use the latest hf patch and select Japanese when starting the installer so that English translations don't get installed (or manually turn off translations in mod select screen). Chinese is only avaliable in Koikatsu Party with all updates (make sure it's up to date on steam).

Ryan Cheng

But my game was not from steam, was download from other website which allow download for free..

ManlyMarco

In that case I can't help you since I have no idea what you have right now. The only fully supported way to get a proper Chinese translation is to use the latest version of Koikatsu Party and HF Patch 2.10.
