Uxn

An assembler and emulator for a tiny stack-based computer, written in ANSI C.

Build

Linux

To build the Uxn emulator, you must have SDL2.

./build.sh 
	--debug # Add debug flags to compiler
	--cli # Run rom without graphics

Plan 9

To build the Uxn emulator on 9front, via npe:

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

The following command will create an Uxn-compatible rom from an uxambly file, point to a different usm file in /projects to assemble a different rom.

bin/uxnasm projects/demos/life.usm bin/life.rom

To start the rom, point the emulator to the newly created rom:

bin/uxnemu bin/life.rom

You can find additional roms here.
