Hello @raenii, I initially assessed this as a Portal 2 issue, but these are standalone mods and in general you shouldn't be smashing Portal 2 files into this game's folder.
In any case, I got Portal Stories: Mel working on my Manjaro test box with a couple workarounds. Please verify the game's files, then rm ~/.local/share/Steam/steamapps/common/Portal\ Stories\ Mel/bin/libstdc++.so.6 and add ./portal2.sh -game portal_stories -steam #%command% to the game's launch options.
The issue is on the game dev's side, the mod should call portal2.sh instead of portal2_linux and unbundle libstdc++.so.6 from the game.
thank you so so so much, i'm surprised i couldn't find any solutions online. you're a huge help.
Portal Stories: Mel should be fixed: https://steamcommunity.com/games/317400/announcements/detail/1771512076693356834
Aperture Tag will most likely need the same treatment.
I just had the same issue with Aperture Tag only, so I had to run it with Proton GE 6.1-2 and works flawlessly.
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
when i open a portal 2 mod, such as portal stories: mel or aperture tag, the game shows as "Running" then it says "Syncing" then nothing. the games don't launch what-so-ever. portal 2 works fine, however. i've tried all the copying portal 2 files into the mod's folders and stuff, none of that works. am i missing dependencies?
