CK III - Checksum is changed on M1 (ARM) based Macs

[Harcker]

Short summary of your issue
Checksum is changed on M1 (ARM) based Macs

Game Version
1.3.0 (1.2.x too)

What OS are you playing on?
Mac

What platform are you using?
Steam

Do you have mods enabled?
No

Have you tried verifying your game files (Steam only)?
Yes

How much "pain" is this causing you?
8

Please explain the issue you experienced in the most condensed way possible
Apple's x86_64 emulation (Rosetta 2) automatically converts the game's binary to ARM, which changes the multiplayer/achievements checksum.

Please explain how to reproduce the issue
Install the game on the internal SSD of an Apple Silicon/M1/ARM Mac, launch the game, notice the checksum is wrong.
It may require multiple launches for the translating to come into effect.

Is there anything else you think could help us identify/replicate the issue?
The issue can be alleviated by installing the game in a Steam Library stored on an external disk.
The issue is present with and without the Northern Lords flavor pack.

Hi again, Harcker!

Just following up regarding this issue; we are lacking this hardware in the dev team, but we can do some remote investigation with your help:

1. Please attach log files from after starting the game with Debug Mode enabled on the affected machine.
2. If you have access to another machine, please start the game on the same version and in the same way on that other machine, and attach those logs as well.
   If you don't we'll need to know the exact version so we can do step 2 on our end.

The log files contain information concerning the checksum calculation, so we can track down which files or potentially mods are causing issues.
Thank you in advance!

My workaround for Ironman-mode us no longer working.

Device:
MacOS Big Sur 11.4 (20F71), on MacBook Pro with Apple M1 CPU

No mods installed, and all available DLC's enabled (Fashion of the Abbasid Court AND The Northern Lords)


I have launched the game twice in debug mode from an external flash drive:

debug.log

version 1.4.4
checksum = 6609

(I forgot to copy the full debug information)

After a reinstall I was able to get the following:
debug2.log:
