Thanks for the mods! Would it be possible to make Hospital Seduction’s animations loop like with the Afterschool Tag mod?

I wanted to do something similar, but I couldn’t figure out how the game controls the animation progression

Thanks for the latest game mods! Not sure if I’m doing something wrong but I can’t seem to get the mod working for Hospital seduction. I tried to get it to work with both the demo and full game, I get the same error.

I’ve gotten this same issue with multiple modded games. I’ve tried different BepinEx versions and cannot get it to work. I even bought the games from DLsite and still nothing. If you figure it out please tag me.

I had a similar issue to Jester a long while ago, except the cmd would just close rather than give that error. Did some back and forth troubleshooting with T04st, but I was going to wipe and re-install windows anyway for different reasons. That ended up fixing it lmao. Overkill but interesting that that worked.

I found this link: How to Fix an Error Code 0xc0000005 on Windows.
Going off @Nitesurgeon personal experience, I think some of these might be worth trying if the underlying cause could be the same.

From that website, try these fixes:

  • Update Your Windows 11 or Windows 10 Version
  • Repair Microsoft .NET Framework
  • Use the Windows Memory Diagnostic Tool
  • Fix Your PC’s Corrupted System Files

My instincts are leaning more towards the last one. But any of these could potentially fix it.

Edit: Just noticed their linked .NET repair is only for older version. Try downloading and reinstalling 6 from here: Download .NET 6.0 (Linux, macOS, and Windows) | .NET
Download the one on the right - the desktop runtime

Thanks for the help! I tried each of those and I didn’t find any corrupt system files or bad memory. Maybe its worth noting but the edi mod for castle of temptation specifically made by Ppower works whereas the edi modded games here don’t, not sure why that is. Changing the BepinEx version makes the game run but no console and doesn’t seem to connect to edi.

Maybe try to run the game and EDI inside the Windows Sandbox. The sandbox is an isolated environment where host-installed software isn’t available which could help pinpoint the issue.

I don’t know if this is valid, but try
rename the “winhttp.dll” file to “version.dll”

That got the game running.

Oh wow that did it, thank you!

I’m really surprised that worked. The bepinex docs list that as a troubleshooting step for older Unity versions. Makes me wonder what set of circumstances lead to this issue.

Here’s the troubleshooting section if anyone else is still facing issues. Maybe there’s some golden nuggets in here after all. Troubleshooting | BepInEx Docs

Hey guys, how do I get the game Syahata’s Bad Day to work with FunscriptPlayer v1.4.4? I’m not managing to put the files in the right folders.

Syahata uses Edi.
Look through the README and check this post for an Edi download: Easy Device Integration for Games. EDI FunSSR1 V2.0 + Preview Device [03/2025]

I had an idea I wanted to try out for this and it seems like it can work.
This is not fully tested yet, but it seems to work with the few enemies I’ve tried.

Also, I don’t know if the scripts will still play correctly with a never-ending loop. If anyone wants to test this out, let me know of any issues you come across.

There are two options added in the config.

  • Replay scenes: Will loop the whole scene back to the beginning like it does when it’s game over. Press ‘x’ to have the looping stop.
  • Loop scenes: Will loop the individual scene without moving to the faster one. Press ‘z’ to allow the game to continue to the next animation.
    This one won’t be instant. The game is keeping track of how many loops the animation has completed and each animation changes on a different amount of loops.
    This hack works by preventing the game from counting the loops. Pressing ‘z’ will allow the game to count the loops again until the animation changes.

It worked perfectly on most mobs.
As far as I remember, it didn’t work on the second nurse and Sadako.

Thanks for for the feedback :slight_smile:
Yeah, those two are a problem. They behave differently from the other enemies.
The nurse’s animation logic doesn’t care about the loops, so it might not be possible to force it to stick to one animation.
Sadako is one single long animation so there’s unfortunately nothing to loop on.

Both should work in terms of the animation looping once it ends.

I have an honest question. Does EDI work better with Handy firmware 3 or 4? Or does it matter at all?
