srb2p 1.3.3 unofficial linux appimage lol

File : srb2p-x86_64.AppImage
Version : SRB2Persona 1.3.3
Based on commit : b32500d0eb314d361ee30d36e890bcc27c60d24a (https://git.do.srb2.org/SinnamonLat/SRB2/-/commit/b32500d0eb314d361ee30d36e890bcc27c60d24a)
Built on : December 29 2021, 11:00 PM using linuxdeploy-x86_64.appimage

To run : Add execute permissions to the file using either your file manager or the command `chmod +x srb2p-x86_64.AppImage`

Required file to get from SRB2 : srb2.pk3 --> You can get it from the windows archived version
	- Note : if you have downloaded srb2 before, it might find theses files automatically, depending on their location.
	- Example : srb2p-data (from the aur) installs srb2.pk3 in a directory that will be found by srb2p.
Other required files
- Put all .pk3 and .wad file in <your home folder>/.srb2
- Note : required .pk3/.wad files will be verified to make sure they aren't different from what was used when building.
	- If srb2.pk3 is corrupt or modified : Try redownloading the latest version. If it still gives an error, ping @Nathan_Nino (It means I need to recompile with the updated version)
	- If another .pk3 or .wad is corrupt of modified : Download the file from the google drive.


Dependencies : Being able to run AppImages. More info : https://docs.appimage.org/user-guide/run-appimages.html
  - Example : You will need to have FUSE. If you don't want to install FUSE, you can always do `srb2p-x86_64.AppImage --appimage-extract` and run `./squashfs-root/AppRun`. Again, easier to just have FUSE and run `./srb2p-x86_64.AppImage`, but if you really don't want to, you still have options.

  - Also sdl2_mixer ([sudo apt install libsdl2-mixer-2.0-0] [sudo pacman -S sdl2_mixer])
	- idk why it isn't included in the appimage, but it isn't.

Working Directory (Logs, config files and addons):
When running, srb2p will put files inside `~/.srb2`. This is also the directory that the addons menu will open up on

Troubleshooting :
- A popup appears talking about a missing .pk3 or a missing .wad
  - Download srb2.pk3 from the official download

- There is no audio (and an error appears when trying to play sound)
  - Check if the music volume is not set to 0. If not :
    - This is probably a alsa issue. You can either configure it properly or get another program to do it for you.
      - Ex: pulseaudio/pipewire.
      - You can check the log for "ERROR: Error starting SDL_Mixer: ALSA: Couldn't open audio device: No such file or directory". If this appears, it's definitively an error with alsa.

- It still doesn't open
  - If you have tried everything else and it still doesn't open, run the AppImage inside a command-line interface, get the error output and send it to me (@Nathan_Nino) on the official srb2p discord (just ping me)


==================
ps : I'm still not that great at this packaging thing, so that's why this is more complicated than a normal .appimage app should be =/ sorry.
