Making AppImages for Unreal Engine 2.5 games

[nesper8]

Hello
I recently got hold of the Linux native binaries for the game Unreal Tournament 2004 which I was able to run off pretty normally on my PikaOS 22.10 (ubuntu-based distro) after a few .so changes like forcing sdlcl and newer version of OpenAL.
But I wanted to future proof this Linux patch so that the binaries wont fall into the dependency hell.

The link to the linux patch is here

I apologize for being unable to include as a screenshot due to sheer amount of files inside and honestly this is my first time trying to make an AppImage so thought posting an issue here so that I could learn from the how tos of appimage straight from the maintainers and make the linux versions of other lifig and loki soft era ports alive myself

Please feel free to close the issue if I'm asking too much

Thank you
