I have a very random question. So I own the game on steam, and wanted to mod the game on steamdeck. I was able to mod the game and create the modded folder with all the files, but I cant boot the mod from the folder like normal, due to it being a .exe.
So I tried to add it as a "non steam game" and while it starts to boot, it keeps giving me an "unknown header error" and thats as far as I've been able to get, so i figured at least see if anyone had any ideas
I've actually gotten my modded game running successfully on steam deck before. Like you, I added it as a non-steam game. The key to success in my case was changing some proton compatibility settings, try seeing if switching a different version of proton in your settings for the non-steam game will allow it to launch.
Thanks for replying! So I tried that a few times, and even made sure to install the game internally, but I kept getting the same "Error Uncaught Error: Header is Wrong" warning over a black screen every time the game boots up, then it just stays stuck on that until I close it. Do you have any idea what the "header" may be referring to?
