What's really cool about PixelVision8 is it's a meta-fantasy console. IE, you can define your own spec/constraints and then code up a little game prototype in C# or Lua.

Looks like the PlayDate will support lua and apparently isn't a complete potato according to their presskit page, so it's not out of the question that platforms like PixelVision8 could port its runner to the platform and then you could author for actual hardware using the editing tool.
