Content

A patch for AI-Syoujyo (AI*少女, the original Japanese release) and AI-Shoujo (the Steam release) with all free updates, fan-made English translations and essential mods. It will improve performance, add features, fix common issues, and allow you to load character cards and scenes found online. All this while still keeping the original, uncluttered feel of the game.

All content is tested and fixed (or removed) as needed before each update. HF Patch can repair many common problems, try it if you have issues with your game or mod setup. By default, it cleans the game before applying new mods, providing a stable platform for further modding. You can apply HF Patch over any game installation or repack without issues.

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

「AI*少女」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。

WARNING: Heelz is known to have some issues in this release. When installing the HF Patch make sure to disable Heelz on the mod list (it's about halfway down the list). 

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

2021-10-31 05:09:04 Thank you! >Edit< H-Scene is bugged. Possibly related to the girl's opening dialogue not starting. Also had to overwrite "AI_UncensorSelector Base.zipmod" with the STN version as the player-female had no uncensor options.

H scene UI not working in steam version Edit: It seems my last edit was disappeared. For me deleting AI_UnlockPlayerHClothes helped. But I will test removing that Heelz and move that AI_UnlockPlayerHClothes back.

Neversoft

Can confirm. You can reactivate the UI using the HideAllUI.AISyoujyo keybind but it remains uninteractive.

Archer

Yeah I just confirmed its not working.... Such a shame it is posible to fix?

Noobkaiser

The H bug seems to be from the "Heelz" plugin. Disabled it with KK and it's fine so far.

ManlyMarco

Thank you for the report, I confirmed that it's heelz breaking it. Fortunately this seems to be the only issue so far.

ManlyMarco

Try removing \BepInEx\plugins\Heelz.dll from the game directory, it should fix the h scene.

Electronic Soul

Thanks for the patch, man! Could you answer a few questions? Does this version include the ability of making the girl taller than 100 like previous one did? Does it improve performance? I installed the previous verison on top of the base game and then I insalled the ecstasy patch. This was the only way the game would work with the ecstasy patch. But unfortunately, some textures were broken and things like nippes just disappeared. I don't know if it was only a problem on my end, but if it's not, then may I ask if this was fixed in the current version? And the last question: could you please update the character height measurement mod? The old one isn't working.

herman925

Is there a mod that allows us to save a card after editing, overwrite the card, but keep the picture? (i.e. I dun wanna ruin some of the photoshopped card that I downloaded)

ManlyMarco

Yes, it includes all features from previous versions. The ecstasy patch is only for the steam release. If you have the steam release then the previous version of the hf patch would break the game plenty and you should verify local game files (from steam library) and install v2.0.1 (if you downloaded v2.0 already that's fine too, only when installing you have to uncheck the Heelz mod).

ManlyMarco

IMPORTANT: If you installed v2.0 HF Patch on the Steam release, remove the "\BepInEx\plugins\Heelz.dll" file (look inside your game directory) to avoid bugs in H scenes. Alternatively you can reinstall the v2.0 HF Patch and uncheck Heelz in the mod selection list. You don't have to download the v2.0.1 HF Patch if you have downloaded the v2.0 HF Patch already. The only change that I've made is to not install Heelz if the Steam version is detected.

ManlyMarco

You should be able to do this by keeping a copy of the original card, and using this tool to apply its image to your copy of the card https://www.patreon.com/posts/card-image-v1-0-32927543

ManlyMarco

I've tested the uncensor bug report and everything worked fine, it might have been caused by Heelz as well.

Neversoft

Great! Thanks so much for your efforts once again. >Edit< I have one other issue. Before HFpatch the girls mouths would align when kissing. Now the taller one seems off, like mouth to nose, off.. Any ideas? (Sorry for being a pest!)

ManlyMarco

It might be the height unlock, by default the game forces both characters to be the same height to make everything line up well but the unlock might make the two too far apart. It's the AI_UnlockPlayerHeight.dll

TJ Wang

Thanks for the patch. Seems Illusion has release several free updates for the DMM/JP version but they say these updates are not applicable for the Steam version, will the HF patch also apply these free updates for the Steam version and change the Steam version from 1.0.0 to 1.0.7?

ManlyMarco

The patch already applies most of those. The version number won't change but you still get features from the free patch like the studio. I'll see if more of the patch can be used for the next version of the patch, most likely yes. They seem to be saying this just because they don't want to localize it to English.

TJ Wang

Please ignore this, I just saw the details in steamcommunity, thanks a lot for the patch

ManlyMarco

Added mega mirror: https://mega.nz/#F!5QMkVQ4K!6ejF82npcxvl4jRx2TsOUg

herman925

Thanks @ManlyMarco. Btw I wonder if you've ever tried this MOD: https://mikkemods.blogspot.com/2020/01/gravure-plugin-for-ai-girl.html It's a tool similar to what yours does, but it's built into the main game itself to save but keep the card.

ManlyMarco

It's on my list of mods to include in the future. Currently this plugin is not fully tested for the steam release so I didn't include it.

Mia K Holster

Hello. I get a Unity crash or something? When I open the character creation now. A small side window opens up called Unity something, with a loading bar. Then everything promptly crashes. Any idea what is wrong here? Here is a picture of the 'Error' https://i.imgur.com/LdTkxxy.png

ManlyMarco

Did it work before the patch, and when installing the patch did you let it remove all old mods/plugins? If you didn't then try reinstalling the patch with all default settings. If that doesn't help you might need to reinstall the game.

Mia K Holster

Yeah, I'm doing a full reinstall now. Figured it might have been because I was confused and might have added mods that does not work with the Steam Version. This time, I'll try just adding the Ecstasy Patch from their site, then the HF patch. Though, if I don't activate the Translation, does something fuck up?

ManlyMarco

If you have the steam release then adding random mods could definitely break something since things outside of HF Patch are generally not tested for this release yet. The translation in the patch only applies to studio and modded items and adds a better launcher with studio and auto update support, so if you're fine with having those then not installing the translation is fine.

Mia K Holster

Ah I see. Well now I can open both the actual game, and character creator. Problem though, and I hope I'm not being too annoying. The whole game is now in japanese, even while the game is supposed to be the English Steam version. When installing the HF Patcher, I didn't tag the Translator, cause I like the offical translation better. Is there a way to keep that or do I have to do the patcher and get the wonky translation? Basically is there any of the Translators I should leave untagged or not?

ManlyMarco

HF Patch only adds missing translations, it doesn't replace the existing ones, so there's no reason not to install them. Make sure that you have English language set in the game launcher if you didn't install the translations from HF Patch (if you did then the patch should force the language to be English).

Mia K Holster

My thanks! It works amazingly now! Thanks for your patience xD Have a good day!

Makoto Neysi

does build anywhere, ignore overlap and Cheating and handy tools scripts work with steam ver ? is yes pls them

RaptorTim

KK Manger is stuck at searching for mods for an hour, I can't download the sidemod stuff. help

2021-10-31 05:08:00 Aaaand I'm back. Very sorry. So, is there a way to get the HF patch, to not redo the entire games text in Japanese? Cause I really can't understand a word written by the Auto translator. It's all just random english gibberish with no sense. Can I somehow just get the Translation, that comes with the Steam version? I see no way to change the written language in game, and in the initial set up menu, if I set it to english. It does nothing. Game is still Japanese -&gt; Auto Translated jumble.

ManlyMarco

Check the disabled.zip archive inside your scripts folder, it contains many of those scripts.

ManlyMarco

If you really have the Steam release it sounds like there might be some issues with your game install. Try to game verify files from your Steam library, delete the UserData\setup.xml file, and make sure you have AI-Shoujo.exe not AI-Syoujyo.exe (if you have anything named AI-Syoujyo in your game directory for whatever reason then you might need to reinstall the game). Then install HF Patch with all default settings.

ManlyMarco

The Language field inside UserData\setup.xml should end up being 1 (English) instead of 0 (Japanese).

Mia K Holster

So, I do another full 100% clean reinstall. Then add the offical patch for Steam. Then add the HF patch. In the patch, do I still tag the Translator or not? If I do, will it only translate Japanese text from mods, or will it force everything to Japanese, then try (and fail) to translate it?

Mia K Holster

The AI-Syoujyo did appear, but I believe it came with the Torrent I had to download with the HF patch,

Mia K Holster

OKAY! Thank you so much and sorry for all the trouble. I read through what you wrote again, and I did as you said. Deleted the unwelcome files, repatched it with the recommended settings. And now it works! Thank you so much, and bless your patience and your work!

Jarvis Somethingorother

Hello, I'm having trouble getting the scripts included in the disabled.zip to load. I unzipped the .cs files and placed them in the scripts folder, but whenever I start the game they don't work. According to the output log I'm getting the same error CS0121 for every script I want to use. Any idea what the problem could be? Everything else seems to work fine.

ManlyMarco

The scripts are not tested in the Steam release, use at your own risk. You might want to ask for updated versions on the discord server.

Jarvis Somethingorother

That's what I initially thought too, but I also tried the JP version via ScrewThisNoise's BetterRepack and it still gives me the same error.

ManlyMarco

The scripts might need to be updated to work with latest versions of script loader.

Stratanael

Hey man, just wanted to say thank you for being so fast with porting it to steam. Since i disovered studio i honestly spent an absurd amount of time with it, with most scenes at least being slightly morally questionable (dont't judge me tho). Tried to message you in your guide on steam, but it disappeared. Anyway, despite having even managed to use custom animations with NodesConstraints, i still search for a method to make a (short) video of scenes (not with screen capture methods like shadowplay). So, if you know a solution, i would appreciate your help.

ManlyMarco

Looks like steam guides are broken currently. You can hide studio interface by pressing Space and record the window with OBS, or use this plugin https://www.patreon.com/posts/32172852

Jarvis Somethingorother

They work using the JP repack before applying the HF Patch, though. They stop working after I install it, so I'm just wondering if installing the HF Patch causes some sort of conflict that breaks ScriptLoader.

Stratanael

Thank you again! I tried to use the plugin für HS, thats why it didn't work for A.I.. Have a nice day and stay healthy

ManlyMarco

This patch includes an updated ScriptLoader, one of its updates broke backwards compatibility with some plugins. They should be fixable fairly easily by editing the scripts based on what errors you get. You can roll back to previous ScriptLoader but it will break the AIPE fix script since it requires the newest version.

Michael

Hey hey ManlyMarco. Mod works great. Thank you for doing an amazing job with it all :). One thing I noticed is when you do a titjob I think the one on its own or including luck or something, the male models penis head is reversed looks very weird and sometimes it spins A bit like as in more than necessary on the shaft like 90 degrees ... anyhoo. Love your work. Thought I’d point that out :D

Michael

Oh and this is with the steam release of the game

ManlyMarco

This is how illusion made the animations, it's normally not a problem because it's a disco stick with no direction. Unfortunately there's no fix at the moment.

Michael

ahh ok thank you :) lol disco stick :P

brian thao

I tried downloading via MEGA and all the bin files downloaded except the exe keeps disappearing. I made sure my firewall was off but every time I download it just disappears. Could be something wrong on my end because my download records show that I have downloaded it. Heck, even I tried the Torrent and the exe file still disappeared. I'm just confused to be honest, because I downloaded the HF patch for Koikatsu Party just fine.

JUI HUNH CHEN

I want to change the language to Japanese.What should I do?

Michael

one more question ... the girls have a chance to get changed into diff clothes sometimes with cupboards and such... but i cannot make any different clothes / outfits... or am i doing it wrong?

Framix

Hi, I have a problem with the Heelz plugin. H scenes don't work because of it, and when I remove this plugin it all works . I have japanese version game .

ManlyMarco

It looks like Heelz got broken in the Japanese version as well. The author knows about this and is planning to fix this, but it might take some time. For now the solution is to remove it and wait. You can join the IS discord server if you want to try and help find the cause of the bug.

ManlyMarco

Simply select Japanese when installing HF Patch, it will uncheck the English translation. If you have the Steam release you might also need to open the game launcher and select Japanese language (do this after installing HF Patch). If you don't want to reinstall HF Patch then remove bepinex\plugins\XUnity.AutoTranslator and bepinex\translation, then go to userdata\setup.xml and change the Language property to 0.

ManlyMarco

It sounds like your antivirus software is removing it for some reason, check quarantine.

brian thao

Yeah, turns out Norton was doing it and not my Windows Firewall. Thanks for the hint and the Patch

Michael

yeah i had a look in htere i couldnt find the option but yeah deff ill have anohter look for that option :)

ManlyMarco

If you want, the game doesn't need them.

ManlyMarco

It's in the same menu as saving the character, might be named "coordinate" not clothes depending on translation.

ManlyMarco

No problem, as more users use the patch the AV programs should stop marking it as risky.

Michael

Question.... on the Launcher it has 3 boxes Play game full screen and then two more that i have no idea what htey mean.. Activate Console and Activate DHH.. what do htey mean? or do?

ManlyMarco

Activate Console enables debug console, it's useful for troubleshooting issues with your game and it's always a good idea to have it turned on. DHH is a graphics enhancement mod, it's off by default because it can drastically change how the game looks to the point where cards made with it enabled are almost useless for people without it, and some people don't like how it makes the game look. After turning it on you have to configure it by pressing P,

Michael

ahh ok thank you Marco :)

Dogwon Lee

Thank you very much. I really appreciate it XD

weikang

asking if i download this patch , steam will automatic update new version?sorry to my bad english

ManlyMarco

After you install this patch you should avoid updating the game on Steam until people confirm that the update works fine or a new version of the patch is released.

weikang

thank, but now i have a problem is the MEGA is over quota using zip now what should i do without paying? and asking on this website http://aisteam.illusion.jp/index_en.php download the ecstasy patch useful?

ManlyMarco

You don't have to download the official patch, it's included in HF Patch. If you hit mega limit you either have to use the torrent download or wait.

lai yee han

i found that got new mod update around 20GB++ , but after i updated feel nothing have improve, and the they say got new extra map

ManlyMarco

All of these updates are for studio only, you won't see any change in the game.

ManlyMarco

How to install HF Patch? Just show it where your game is installed when asked and keep clicking next.

tronophono

the magnet link doesnt work

ManlyMarco

Are you sure about that? It can take some time for the download to start. You can get a torrent file from the mega if you can't get the magnet to work.

Karnstein

i have a glitch with the girl high heels in character creation, anyone know how to fix it?

ManlyMarco

Heelz is known to be buggy, report the bug to the creator (hooh) on the IS discord server or on the repository here https://github.com/hooh-hooah/AI_Heelz/issues

Patrick Mc Knew

I've reached the limit for mega, I've downloaded the torrent file, but I don't know what to do with it can you help me, please?

Sean

During the H scenes, the pleasure meter is no longer visible, and the finish button at the bottom doesn't seem to work on the female when attempting to please them. Is there a workaround for this? I have the Steam version, and have deleted the heelz.dll file.

Sean

Re-installed 2.0.1 patch with no change. Still no pleasure meter.

ManlyMarco

Post your output_log on the discord server in the help channel and ping me.

RMarco21

Will this patch make the Steam 1.00 version be updated to the Japanese 1.07 version?

ManlyMarco

It will add most of the missing functionality but the version of the game will not actually change.

Enoch Choi

if u download ecstasy patch from the game website after the hf patch, would there be any conflict i would have to worry about?

ManlyMarco

HF Patch already includes the e patch, you don't have to install it after installing HF Patch.

ManlyMarco

If you installed it anyways you might overwrite some files and have to reinstall HF Patch.

Ka K Chan

hello sir. The mega link seems to be broken...

ManlyMarco

My mega account has been banned and I'm looking for alternatives. For now you can still use the magnet link to download it.

Ka K Chan

Thank you for replying sir. I already downloaded it with magnet and i suggest dropbox as an alternatives option. Thank you for sharing this HF patch.

a Ανόητος

I have downloded the torrent file.But it conclueded "AI-Shoujo HF Patch v2.0.1"‐1,2,3,4and "ALL exe AND bin FILES ARE NECESSARY, USE THE torrent FILE TO DOWNLOAD IF YOU HIT THE MEGA LIMIT".I couldnt find exefile. How it begin startup?

KarmaSpud

Hi marco,I seem to be having a weird problem with the exe,I downloaded it with the magnet link,it asks me where I want to install it,it stops after after clicking next saying there is critical files missing,for Koikatsu which I don't own.The HF patch is the link you provided above and the files are for Ai Shoujo,but why is it looking for Koikatsu ?

KarmaSpud

Btw I have tried downloading it again and its the same file,get the same warning etc.

ManlyMarco

The message is wrong, it's actually looking for AI files. Make sure you are installing to the correct game directory. If it still shows you the message, you might need to reinstall your game.

KarmaSpud

ok thx

りー

Installing, The original file is shown as corrupted

ManlyMarco

Make sure your HF Patch download is not corrupted. If you downloaded it through torrent then make your torrent client check validity of the downloaded files, or try to download again.

leoliu

there is an updatee today do I just reinstall the hf patch?

ManlyMarco

It looks like the update should not affect the patch at all. Try running the game as normal, and if you can see any issues then reinstall the patch (you will not lose the game update).

Foxy

How can I keep playing with my original language (Traditional Chinese) on Steam while using this HF Patch? I tried not to download the English translation and it works, but which means I can't activate the DHH without the multilangual launcher. Is there any way I can activate the DHH without downloading the English translation? Thanks for the great work!

Michael Bates

Is there something wrong with the torrent link? I can't seem to connect to any peers for the download.

ManlyMarco

Click the Chinese flag in launcher to switch the language. Keep in mind that this patch does not contain the latest game update, I will release an updated version later this week.

ManlyMarco

Update your torrent client or try a different one. qBittorent is known to work well. You might also need to wait for some time for the download to start.

Michael Bates

I was using uTorrent and switched over to qBittorent. Cleared the problem right up, thanks for the help.

Foxy

Tried to click the Chinese flag in launcher as well, which changed the language of the launcher into simplified Chinese, but after enter the game, still all in English.

FuuChan

Hi, I bought and downloaded the game from Fanza and patched it with HF immidiateley. but when I enter my first H Scene. The girl went into the "Waiting Position" and the game stopped responding. I cant even exit the scene or open any options. I have the error codes from console window if you want to take a look at it.

Rapheal Lim

helo, is there any patch only download link? i try to use the magnet link above but the speed is way too sly, i have download it for 1 day but only 6%. or any other direct download link?

ManlyMarco

No links for this version. I'll be releasing a new version most likely tomorrow and that will have direct download links.

Izzy

When i try to download through torrent, the 2nd bin file is incomplete at 99%

cwj40988

Hello, the game on steam has officially update the traditional and simple Chinese version, but if the hf patch is installed, there is no way to choose the Chinese as display language. Would you like to solve this problem, thank you very much!

ManlyMarco

What torrent client are you using? Try updating it. Also try turning it off completely and back on, and try to make it re-check the downloaded files (depends on the client, usually it's somewhere in right click menu).

ManlyMarco

The new version will have support for this, I plan to release it tomorrow.

Averil Chan

Hello, I have already install v1.0, and it work well! However after I updated to v2.0.1, I have some problem: I can not exit H Scenes, two characters just stop and I can not do anythings, can you help me? THK!( I am a DLsite version and updated to 1.07)

Kittipat Chandaket

ummm...I am new to this game...so...if I downloaded this ,do I have to download AI Shoujo/AI Girl SR1 Modpack? Are they conflicted to each other?

ManlyMarco

No, this is all that you need. The modpack might or might not conflict with the patch if you apply it afterwards. You can install the patch over the modpack (or almost any game setup) without issues.

蒼月

Hi, is it going to be possible to play as a female main character and use sex toys etc. in the game? Thanks

jiangzeming

有部分文件损坏无法安装,删除重新下载后仍然损坏。跳过直接安装则无法开始游戏,请问如何解决?谢谢。

jiangzeming

Some files are damaged and cannot be installed. They are still damaged after being deleted and downloaded again. Skipping the direct installation will not start the game. How to solve this problem? Thank you

ManlyMarco

First of all please try the latest version of the patch https://www.patreon.com/posts/hf-patch-for-ai-36950168 If you have the game on Steam then go to your Steam library and verify files of AI-Shoujo before installing the latest HF Patch.

Ruizhe Zhang

how do i suppose to change language ? i clicked chinese flag on setting but nothing changed. Did i miss something?

ManlyMarco

Changing language to Chinese is supported since HF Patch v2.1, you have to update to the latest patch.

กฤตานน พันสว่าง

I'm already download torrent link but when i double click to run .exe file , it don't seen anything happen. How can i install it (already install full game from stream and already install ecstasy patch)

ManlyMarco

First of all this is an old version, the latest is here https://www.patreon.com/posts/36950168 Make sure your antivirus isn't blocking it from starting, and that the download isn't corrupted. Try to restart your PC and move the patch files to some other directory like to your Downloads folder.
