Sup gamers.
Super new to Linux gaming after a brief stint in 2011-2012 with Ubuntu before I shorted my laptops battery by ripping the screen off (woops)

Anywho, I'm trying to run runelite through steam as old school runescape with the launch options: echo "%command%"; /home/zidane/Downloads/RuneLite.AppImage

First off, no idea what any of the options are doing and searching online is no help so I can't fix it myself...

But this is my problem... The game (runelite not osrs) opens briefly once, closes, and then opens a new runelite which I'm assuming is making steam no longer think that it's running old school RuneScape? I'm able to play but I want steam to know I'm playing so number go up on steam while number go up in game.

Edit:
opening both the RuneLite.AppImage & RuneLite.jar does the ol opens and closes and reopens itself again... And I have read/write + execute as program enabled... surely I messed something up?

opens closes and opens runelite
echo "%command%"; /mnt/Games_Linux/RuneScape/RuneLite.AppImage
"%command%"; /mnt/Games_Linux/RuneScape/RuneLite.AppImage
/mnt/Games_Linux/RuneScape/RuneLite.AppImage
/mnt/Games_Linux/RuneScape/RuneLite.AppImage # %command%
/mnt/Games_Linux/RuneScape/RuneLite.AppImage "%command%"

opens runelite and then doesn't reopen?????
/mnt/Games_Linux/RuneScape/RuneLite.AppImage %command%

opens original launcher
echo java -jar /mnt/Games_Linux/RuneScape/RuneLite.jar
java -jar /mnt/Games_Linux/RuneScape/RuneLite.jar
java -jar "/mnt/Games_Linux/RuneScape/RuneLite.jar"
-jar /mnt/Games_Linux/RuneScape/RuneLite.jar
%command% java -jar /mnt/Games_Linux/RuneScape/RuneLite.jar
