You can install the stable Steam version of GameMaker in Proton! I do that on SteamDeck.

I had ironically avoided this in the theory that running Gamemaker through Proton layer would introduce some extra instability or something. lol Thanks, that did work (and I wasn't expecting that.) Even works creating a Windows based game with a working lua script test, just outright. Wrapping this back to Linux directly (So, again the beta builds) it now imports properly, but I can't get it to work properly, apparently not creating a state. (Windows multiple states follows the standard 0, 1, 2, etc. Linux stays at 0, 0, 0, and the scripts don't trigger.) At this point, I'm unsure if it's because Linux beta GMS something, or the .so isn't triggering properly. I'd love to provide more information if I could, except that I'm woefully incapable of diagnosing this. (Being I'm listening to Chat-GPT, ugh, and running Ghidra with GPT's instructions. lol) So, sorry to uh.. "Dump" this problem back onto you, otherwise. :S If you by chance need anything from me, please do let me know.
