# Uxn An [8-bit stack-based computer](https://wiki.xxiivv.com/site/uxn.html), written in ANSI C. ## Build ### Linux To build the Uxn emulator, you must have [SDL2](https://wiki.libsdl.org/). ```sh ./build.sh --debug # Add debug flags to compiler --cli # Run rom without graphics ``` ### Plan 9 To build the Uxn emulator on [9front](http://9front.org/), via [npe](https://git.sr.ht/~ft/npe): ```rc mk ``` If the build fails on 9front because of missing headers or functions, try again after `rm -r /sys/include/npe`. ## Getting Started Begin by building the assembler and emulator by running the build script. The assembler(`uxnasm`) and emulator(`uxnemu`) are created in the `bin` folder. ``` ./build.sh ``` This example will create the `life.rom` from the `life.usm` uxambly file, point to a different usm file to assemble a different rom. You can find additional roms [here](https://sr.ht/~rabbits/uxn/sources). To create a rom, from a [usm file](https://wiki.xxiivv.com/site/uxambly.html), use the following command: ``` bin/uxnasm projects/demos/life.usm bin/life.rom ``` To launch the rom: ``` bin/uxnemu bin/life.rom ``` ## Emulator Controls - `ctrl+h` toggle debugger - `alt+h` toggle zoom ## Need a hand?
