It was developed in assembly.&lt;br /&gt;
&lt;br /&gt;
This was the engine for the [[Hi-Res Adventure Series|Hi-Res Adventure series]]. Dithering was added to the interpreter to simulate a 21 color pallet from the Apple II&amp;#039;s 6 color pallet. This can be seen in &amp;#039;&amp;#039;[[Wizard and the Princess|Hi-Res Adventure 2: Wizard &amp;amp; the Princess]]&amp;#039;&amp;#039;.&lt;br /&gt;
