A while ago I saw this video about #EGA / #CGA decoding with an #EPROM, so I decided to implement a variant adding a buffer on the output and writing my own map generator to build the EPROM image (I did not like the Google sheet based tool and I wanted the ability to customize the color maps). Surprisingly it worked on the first try. I might just release the tools and PCB after some testing.
