Assembling a basic source file is simple:
<div class="Pp"></div>
<div class="Bd" style="margin-left: 5.00ex;">
<pre class="Li">
$ rgbasm -o bar.o foo.asm
</pre>
</div>
<div class="Pp"></div>
The resulting object file is not yet a usable ROM image — it must first
be run through <a class="Xr" title="Xr">rgblink(1)</a> and
<a class="Xr" title="Xr">rgbfix(1)</a>.

<b class="Nm" title="Nm">rgbasm</b> was originally written by Carsten

RGBDS by Justin Lloyd. It is now maintained by a number of contributors at
