How does the EGA640.DRV even work?

Post by Good_Punk »

I've recently stumbled over this driver and how it "emulates" VGA graphics on an EGA display.
Has anybody here taken a closer look at it and can explain to me how this thing works?

I'd be interested to create a youtube video on the topic and I would like to explain what that driver does and how it achieves the dithering and how it slots into the Sierra engine.

Generally any information on that thing might be helpful and highly appreciated. :)
