Older gamelauncher.sh doesn't work for me (fixed locally, but this repo's script isn't?)

[New9c]

TLDR

The .local/share/bin/gamelauncher.sh (where the old version placed the launcher) worked until one day it didn't. Steam probably updated how they store their images. After simple changes to the script the launcher works again, but I wonder if the script should be updated here and whether the issue ever occurred to anyone else.

Problem

One day, I used the game launcher as usual, but there weren't any images, nor could it open any games.
I then ran it using the terminal, and here's the message:

process:24926): Helpers.IconFetcher-WARNING **: 10:57:27.350: Failed to load image: |/home/myname/.local/share/Steam/appcache/librarycache/_library_600x900.jpg| 207 207 Failed to open file “/home/myname/.local/share/Steam/appcache/librarycache/_library_600x900.jpg”: No such file or directory ((nil))

Fix

Using grep, it became clear that at least for my computer, the images are now at ${appid}/library_600x900.jpg instead of ${appid}_library_600x900.jpg, same with ${launchid}/header.jpg instead of ${launchid}_header.jpg, changing _ to / in the three parts of the code fixes everything.

Questions

It seems like a lot has happened since I was around. The script here still uses underscore, and I don't know if that will cause problems for anyone else. Also, since I'm worried all my configs will disappear, I haven't installed the newest version yet, so I couldn't quite make the new script in this repo work as intended on my computer. Hope someone a bit wiser than me can see if changes to the script should be made.
