Upscaling Classic Sierra On-Line Adventures

Hackaday’s Matthew Carlson points to an effort to make the graphics in old Sierra On-Line Adventure games better. The graphics in the games in question weren’t stores as raster images, but rather drawn with vector commands, so theoretically it should be easy. But as the video demonstrates, the resolution of their coordinate system didn’t take into account the possibility that someone might come in later and draw the art into a canvas with higher resolution, which causes some weird glitches that had to be accounted for.
