Probably the easiest way to run it is with Vinegar, a Wine wrapper for Roblox. You can just install it from Flathub (or Discover on Steam Deck in Desktop Mode), make a configuration file in terminal to set it to Vulkan and then you're good to go after that:
mkdir -p ~/.var/app/io.github.vinegarhq.Vinegar/config/vinegar/ && { echo "[player]"; echo "dxvk = false"; echo "renderer = \"Vulkan\""; } >> ~/.var/app/io.github.vinegarhq.Vinegar/config/vinegar/config.toml
I know there's a launcher called Grapejuice that's very popular for running the game as well, but I don't know if there are any additional steps needed to get it to work.
Same. I know it matters to a lot of younger players though, my son's game requirements to consider getting a steam deck are beamNG and Roblox support.
Make sure your kid’s safe on there. I know that sounds an awful lot like pearl clutching, but besides the general dangers of children being online Roblox is exceptionally exploitative of anyone creating content on the site(where have we all heard that before?)
I dread the day my kid discovers it. Managed to make windows not a thing at home, was hoping this bollocks is never coming back to linux.
Every game supporting the SD is a good news, I was just fucking around ;)
