How to use

• Download the program

  • Download the ZIP folder here, then extract the folder somewhere you'll remember
    • Alternatively, you can download it through git: git clone https://github.com/meow6969/plutonium-linux-launcher
      • It will create a subfolder called plutonium-linux-launcher, open that folder

• To run the program, open the folder we just created in the last step, then open a terminal in that folder

  • Right click > "Open Terminal Here" (This could be different depending on the OS)
    • After the initial setup, do this step again to play Plutonium

• In the terminal we just opened, enter the command bash start.sh

• Follow the instructions the program gives you

If your game crashes with the error eventfd: Too many open files what fixed it for me was changing the start script a little bit:

#!/bin/bash
export WINEARCH=win64 
export WINEPREFIX=~/.wine_plutonium
export WINEESYNC=1

wine plutonium.exe

change line 4, export WINEESYNC=1 to export WINEFSYNC=1
so your start script would look like this:

#!/bin/bash
export WINEARCH=win64 
export WINEPREFIX=~/.wine_plutonium
export WINEFSYNC=1

wine plutonium.exe

and done! There shouldn't be any more crashes, I hope this helps someone.
