I believe the PC version used palette switching for a lava effect, but not for scrolling (it used Direct X). Never got to see the Mac version of the game. I wrote a bot for Diablo 1 (https://sourceforge.net/projects/projectsolo/ https://sourceforge.net/projects/projectsolo/). Due to the way the game uses older Windows modes for the palette, the colors never come out right in screen captures and also get messed up if you alt-tab. IIRC I had to use an API call dating back to Win16 to get the raw bytes, and I used artificial color for the visualizations rather than figure out how to obtain the actual palette.
