Made an experimental #AppImage of +Libretro RetroArch, including all available cores it weighs in at 240 MB. Thanks to binary delta updates, you only have to download the 0,7% that actually have changed to go from the Oct 1 to the Oct 2 nightly...

In case you wonder, an AppImage is a filesystem image that contains a Linux application and everything it needs to run that is not part of each target system. AppImageUpdate is a binary delta update mechanism that updates an AppImage by only downloading the bytes that have actually changed between the version you have and the latest version.
