Helped by some existing tools and reverse engineering work, I got my Miuchiz handheld from like 2006 to display my character. The plastic in front of the screen is really bad though. If I can replace that it'd be cool as a little portable 6502 computer.
Here's one with better contrast, at least. I used the version of my avatar I did for the nesdev forums where I traced over it and used NES colors, so the lines are a lot blacker.
