Shiginima Launcher (NOT OFFICIAL)

About

Shiginima Launcher: Sponge Edition is an alternative Minecraft Launcher. The files in this git repository allows us to create a Flatpak build of it.

FAQ

Q: Why a Flatpak build of Shiginima Launcher?

A: Flatpak allows us to provide a better desktop integration for Java programs, while also improving security by running the launcher in a sandboxed environment, e.g. preventing mods from accessing sensitive files and folders on your computer.

Q: Are you a member of Team Shiginima?

A: No, not at all. I also don't know anyone who's part of the team. I simply like the launcher for its simplicity and wanted to make a Flatpak build of it.

Q: Do you have the source-code of Shiginima Launcher?

A: Nope.

Q: Will this work on Windows?

A: No, sorry. This is only intended for Linux distributions.

Q: Minecraft doesn't seem to open anymore, what to do?

A: Try running flatpak update, then re-open the launcher. If that doesn't work, feel free to open an issue.

2. Download the latest release of the launcher.

   flatpak install Shiginima_Launcher_v4.400-*-x86_64.flatpak

4. You're good to go! You can find the Shiginima Launcher under Applications > Games.

IMPORTANT: Your game files, including worlds, mods, shaders, etc. will be in ~/.var/app/com.teamshiginima.ShiginimaLauncher/data/minecraft/ and not in ~/.minecraft/!

Uninstalling

In a terminal window, run:

flatpak uninstall com.teamshiginima.ShiginimaLauncher

Additionally, if you want to delete Minecraft itself, including worlds, mods, shaders, etc. you'll have to delete this folder as well: ~/.var/app/com.teamshiginima.ShiginimaLauncher/.

About fix_jvm_args.patch

This patch file simply removes two incompatible Java launch options: -XX:+CMSIncrementalMode and -XX:+UseConcMarkSweepGC. Although this patch file is not mandatory to make the launcher itself work, it is required to make Minecraft run out-of-the-box, as these two options are incompatible with the Java Runtime version we're using (16).
