# Uxn11

An emulator for the [Uxn stack-machine](https://wiki.xxiivv.com/site/uxn.html), written in ANSI C. The emulator contains a few linux specific utilities in the Console device to allow for it to interface with the unix systems.

## Building 

### Graphical

All you need is X11.

```sh
gcc -Os -DNDEBUG -g0 -s src/uxn.c src/devices/system.c src/devices/console.c src/devices/screen.c src/devices/controller.c src/devices/mouse.c src/devices/file.c src/devices/datetime.c src/uxn11.c -o bin/uxn11 -lX11
```

### Terminal

If you wish to build the emulator without graphics mode:

```sh
gcc -Os -DNDEBUG -g0 -s src/uxn.c src/devices/system.c src/devices/console.c src/devices/file.c src/devices/datetime.c src/uxncli.c -o bin/uxncli
```

If do not wish to build it yourself, you can download linux binaries for [uxnasm](https://rabbits.srht.site/uxn11/bin/uxnasm), [uxncli](https://rabbits.srht.site/uxn11/bin/uxncli) and [uxn11](https://rabbits.srht.site/uxn11/bin/uxn11).

## Usage

The first parameter is the rom file, the subsequent arguments will be accessible to the rom, via the [Console vector](https://wiki.xxiivv.com/site/varvara.html#console).

```sh
bin/uxnemu bin/polycat.rom arg1 arg2
```

## Devices

The file device is _sandboxed_, meaning that it should not be able to read or write outside of the working directory.

- `20` screen
- `80` controller
- `90` mouse
- `a0` file
