I extracted a zip file on my Windows 11 laptop. It has a single file inside: ditherdragon-linux.x86_64
Using WSL (windows subsystem for linux) I can't open or run this. Any suggestions?
I can wrong, but I remember the windows WSL is command terminal only (similar to SSH).
A lot of linux game require you start the X11 (X Window System or Display manager), I don't know is possible start the X11 under WSL, if not, you need a VM with a full linux distro.
When you run the application, don't have any error message?
PS: I looked the game and found a graphic tool for pixel art with that name, they have a windows version too.
Isn't it better that you use the windows binary?
What are you trying to do, and what happens? In principle you should enter this at the command prompt (from the directory where the game is):
chmod a+x ditherdragon-linux.x86_64 # just in case ./ditherdragon-linux.x86_64
But since you're on Windows, you should probably just use the Windows version if there is one.
