# Uxn
|
|
|
|
An assembler and emulator for a [tiny 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
|
|
```
|
|
|
|
The following command will create a rom from an [uxambly file](https://wiki.xxiivv.com/site/uxambly.html), point to a different usm file in the projects folder to assemble a different rom. You can find additional roms [here](https://sr.ht/~rabbits/uxn/sources).
|
|
|
|
```
|
|
bin/uxnasm projects/demos/life.usm bin/life.rom
|
|
```
|
|
|
|
And, to start the rom:
|
|
|
|
```
|
|
bin/uxnemu bin/life.rom
|
|
```
|
|
|
|
## Emulator Controls
|
|
|
|
- `ctrl+h` toggle debugger
|
|
- `alt+h` toggle zoom
