Im in need of some help. I've been trying to get back to BICE with no luck. Even though vanilla loads fine, any version of BICE keeps crashing on the loading screen. I did switch to a new PC last year which runs on windows 11. Could that be an issue?

Guys, this legendary mod is still supported and well (as of 2023).
Sadly due to some issues, devs can't post new version (11.3.3) here.

You can download the mod from official Paradox (creators of Hoi3) site.
There is a BlackICE modpage there.
To see the modpage, you will likely have to register your copy of the game.

Dealy beloved BICE gang:

I have the opportunity to help the game Supreme Ruler Ultimate, to be modded to display NATO counters on the units. This is a something I am volunteering to do and there is no money in it. Is it possible to be gifted graphics files that were used in the counters display for HOI 3? I could then convert them to 1024x1024 PNG files for each unit. Any help?

Can this be a practical replacement for lack of the DLC?
