Had also troubles using SSD drive and SH4 (SH3 too)
Had to re-install it on the second mechanical drive to solve all the glitches!
I suspect those games are too old for the SSD tech...
My SH5 is fine on the SSD though, but it’s « newer ».

As a data point I have SH4 v1.4 loaded from CD upgraded to v1.5 using the UBoat missions add on, mostly stock and installed on a Samsung 850 EVO 500GB SSD data drive (Windows 10 is on another SSD) and it works flawlessly

So sh4 uboat missions is a standalone game? You don't need the original SH4 to install it?

No stand alone, you need SH4 Pacific to install UBM :yep:

ok, that makes me feel a lot better.

I bought SH 4 when it came out, (2007) and it's still on the same external HDD.
We use to play SH 3 at work and brag to each other about our prowess with our U Boats, but when SH4 came out it had moved up a gear and was a natural progression and became the pinnacle of pure simulated Submarines.


It had a wide screen, better graphics, a more intricate battle area, nasty opponents and I got to play the good guy, instead of the enemy.


I was disappointed when the update 1.5 turned out to be more U boats. It could so easily have been RN subs, which were very active in the Pacific.


TMO is my mod of choice and it never goes wrong.


The base and U boat update is available on Steam.


:yeah:

Ubisoft are currently selling SH4 Gold edition in their store. They have sales frequently, I managed to pick up my copy for £4.25 just over a week ago but it is currently £12.49 for UK buyers.

I've played a lot of SH3 (Grey Wolves) in the past, and SH4 is just as good if not better. A few mods are needed e.g. to make the dials bigger, remove the grainy graphics effect and reduce the number of aircraft that spawn.

Managed to sink a Jap fleet carrier but it took 4 torps before it went to the bottom.

Love the missions, definitely adds variety compared to SH3.

There is nothing wrong with SH4 out of the box. Quality was on par with SH3. Most of the early complaints came from posters who just did not like anything other than U-Boats.

SH4 out of the box on release was absolute trash, this is coming from a fleet boat fan. The various patches fixed a lot and the end result at 1.5 is a much improved game over release.

Dsrk Waters crashing
 

Sorry to jump on this tread but its the closest I’ve found.

I have steam SH4 and the U-boat addition so v1.5. I’ve manged to get it working ok with Win 10 (cough) anyway I’m keen to use the Dark Waters mod, it looks fantastic. I’ve installed but it crashes when I try and start the career. uninstalled it and game works fine again so I’m fairly sure its the mod. anyone have any expertise or advice on this?

The first question you'll get is "Did you delete the save games under documents?"
That seems to be very important to make the new version (or Mod) work properly.

Hi Thanks for taking the time to reply. Yes i did a clean install and removed the config and savegame folders. all seems ok until i press start to go to the undocked ship, the loading screen works, box with 'please wait' loads then the screen goes black and small windows dialog box with 'unknown error' OK.


P.S. just tried a quick mission and the same thing... (My gut tells me its prob a grapics issue.) unload Dark Waters mod and all works again.

-- Anyone else got SH4 Uboat Missions 1.5 (steam) and Dark Warters mod running on Win 10 ? --
