Program code is obfuscated and (intentionally) invalid according to the CLI spec, so Mono struggles with it.

Compatibility Report

  • Name of the game with compatibility issues: Zeit²
  • Steam AppID of the game: 33390

System Information

  • GPU: AMD integrated (780M), but also happened on my previous Intel-based laptop
  • Video driver version: Mesa 25.0.1
  • Kernel version: 6.13.6-arch1
  • Link to full system information report as Gist: TODO
  • Proton version: Proton Experimental (TODO, exact version)

I confirm:

  • [X] that I haven't found an existing compatibility report for this game.
  • [X] that I have checked whether there are updates for my system available.

Symptoms

The game doesn't launch. The error message mentions an unknown IL opcode.

Proton log: TO BE ATTACHED

The game generally doesn't run out-of-the box in Wine. I have only ever managed to get it to start in a 32-bit prefix after a lot of work trying to get the correct .NET and XNA frameworks installed. I'll add exact steps to get a working prefix here later.

Reproduction

  1. Install the Game
  2. Start the game
  3. Notice it doesn't launch

Note

I'm writing this report from my phone, I will add extra details once I get back to my Laptop. In the meantime, I'm sorry for the incomplete report.

I somehow didn't find this. Sorry for the duplicate

Outdated Info I'm currently trying to write up whats needed in addition to what steam automatically tries on first setup to get this game to run, both in 32-bit and 64-bit prefixes (currently haven't gotten it to rn in 64 bit prefixes)

32-bit prefix

Required for game to start and be playable:

  • dotnet35sp1: required to get past obfuscation

Required for game to render help videos:

  • currently testing this, no success for now (quartz? wmp9? qedit?)

Known Issues:

  • game only starts when in full screen, sometimes has trouble launching when something else is already fullscreen (crashes)
  • audio engine seems to have some issues. main menu intro sound effect repeats every 10 or so seconds. in-game audio only plays the first few samples of the intro, but then immediately skips to the loop. Otherwise audio and sound effects work fine

64-bit prefix

TODO

EDIT: As I already described in ProtonDB and as @F1ReB4LL reminded me, the game runs fine with the following tweaks:

  • ProtonGE 10-21 or later
  • protontricks dotnet48
FF1ReB4LL 2025-11-22 github

The game works under GE-Proton10-21 after installing dotnet48 through protontricks.

Thanks for reminding me of this issue! I recently got it working and posted on ProtonDB, but forgot this GH issue.
