Running libGDX Games

Prerequisites:

• Your game needs to include arm64 libraries for libGDX and LWJGL. You can check this by opening the .jar file in a zip viewer and looking if there are any filenames ending in arm64.so
• Your game must be able to run on OpenGL 2 or OpenGL ES 2. (GL 3 support is coming at some point)

Required Runtimes:

• Westonpack 0.2.5 or higher (weston_pkg_0.2.squashfs)
• JRE 17 or higher (zulu17.54.21-ca-jre17.0.13-linux.squashfs)
