This is how it works: SH4 and Win 10

[⚓ 🅵🅸🅴🅳🅻🅴🆁]

This is what worked for me. I got Silent Hunter 4 to work in Windows 10.

[01] - Purchase, download and install SH4 just as any other Steam-game.
[02] - Run Steam. Go to LIBRARY. Select SH4.
[03] - Open settings on the right. Open game-folder, it looks like
C:\Program Files (x86)\Steam\steamapps\common\Wolves of the Pacific
[04] - In there, find the file SH4.EXE.
[05] - Make a right-click on it and click PROPERTIES
[06] - You see a COMPATIBILITY dropdown tab with the text
"Run this program in compatibility mode for"
[07] - Select "Windows XP SP2"
[08] - Look to "Change high DPI settings", a dialog opens.
[09] - Find the box with "Use this setting to fix scaling problems"
[10] - Check that.
[11] - Find the box with "Override high DPI saling behavior"
[12] - Select "Scaling peformed by" to "Application"
[13] - Exit with OK.

Now you can start the original vanilla game and enjoy.

Extra steps that I took to run mods with this game:

[14] - Run Steam. Go to LIBRARY. Select SH4.
[15] - Open settings on the right. Open game-folder, it looks like
C:\Program Files (x86)\Steam\steamapps\common\Wolves of the Pacific
[16] - Go 1 folder up, you're now in "common" and see the game-folder.
[17] - Make a right-click on it and click CUT.
[18] - Go to a location totally elsewhere on your hard-drive.
OUTSIDE Steam!
OUTSIDE any folder controlled by Windows!
NOT in "Programs" or any other Windows-folder
I created E:\SH4
[19] - Go into that folder.
[20] - Make a right-click in it and click PASTE.
[21] - Download Steam-Fix-for-SH4[rb.gy] and unpack into this folder, too.
[22] - Download 4GB-Patch by NTcore[ntcore.com]
[24] - Run 4GB-Patch.EXE and apply to SH4.EXE
[25] - Only cosmetic: Rename "Silent Hunter Wolves of the Pacific" to "SH4-original".

With these extra-steps I achieve that...
- Steam doesn't anylonger disturb my game-play or cause crashes.
- Steam doesn't anylonger "verify" the SH4-game-files.
- Steam doesn't anylonger remove the changes that I want.
- Steam doesn't anylonger remove the mods that I want.
- I can also run with mods that require more memory without crashing.

⚠️ Everybody who used this quick-guide, please post here!

Give feedback or even an award.
Did I miss something? Can anything be done in a better way?

⚠️ I recommend to try these mods with SH4:

DW - Dark Waters, by Fifi
KSD2 - Knights of the Sea Depths, by KSD-Team
OM - Operation Monsun, by Lurker
RFB - Real Fleet-Boat, by RFB-Team
TMO - Trigger Maru Overhauled, by Ducimus

▪FREE DOWNLOAD OF THESE MODS▪[rb.gy]

I also recommend to turn to Ubisoft's original Atlantic Theatre:
Silent Hunter: Wolves of the Pacific U-Boat Missions

"Download SteamFix4SH4 and unpack into this folder, too."

Where do i find that file?

The first tricks - after step [05] - are overkill on my end.
The "Override high DPI saling behavior" box is enough.

P.S.: One can also tick "Disable fullscreen optimizations" as these optimizations seems useless here. Disabling may improve performance.

Your mileage may vary. This is an attempt to have generic solution that works for everyone, not for some only.

Seems Steam boycotts both Mediafire and tinyurl, so it took me a while to figure that out until it worked...

[Thermal Lance]

Weird. All I do is installing the game and press play. Both on an old ass installation and fresh install of Windows 10. I have no idea what's causing people problem with that.

[USS Midway veteran]

Very good, Fiedler, Thanks

[Psycho_Soyer]

Nice. It worked for me.

[VipreRX]

Regarding 21 and 24 which exe are you supposed to run afterwards?

The exe in the Steam-Fix-for-SH4 is SH4 dot dot exe.

Are we supposed to apply the 4GB patch to SH4.exe as instructed in 24 and run that, run sh4 dot dot exe instead, apply the 4gb patch to both and then run sh4 dot dot exe, if I follow the dirctions exactly as written I get a steam application error trying to run sh4.exe.

Thanks worked as advertised... Installed using the original disk that I purchased long ago...

[shadokitty]

Cheers. Thanks to this post, I finally got it working.

the tab doesn't come up when I open the Propeties on SH4.exe it only shows like 4 tabs

Sweet 10/10 works like ah charm. Now I can watch some old school American Submarine movies and play this game as god intended!

[Red1Alpha]

How to patch to v1.4? I tried the UL folder update but I still see v1.3.
