Our general cross-platform desktop emulator requires SDL2, alternatively, you could download the plain Win32 or X11 versions, but we will not cover these in this guide. If you don't have SDL2, here's how to get it:

sudo pacman -Sy sdl2             # Arch
sudo apt install libsdl2-dev     # Ubuntu
sudo xbps-install SDL2-devel     # Void Linux
brew install sdl2                # OSX
doas pkg_add sdl2                # openBSD

Double-click on uxnemu to launch it, on some Linux distribution, it might not be possible to do so, if for some reason uxnemu is not be clickable, navigate to the downloaded files in the terminal and launch it from there. To launch the ROM from the terminal, point the emulator to the target .rom file:

bin/uxnemu path/to/example.rom

The Uxn emulator can play rom files, which are small portable applications for the system. The Uxn package comes with basic applications, but there are many more to try, view the full list of available applications.
