My Color Computer 2 does NOT have the extended basic ROM. I kinda like to keep it that way since it's less common and it's kind of quaint.
But Color Basic has absolutely no commands for the graphics modes of the Color Computer!
While I was working on some other stuff, I decided to try anyway. Here is the result of that. I've left it kind of obfuscated on purpose, if you have any questions ask me.
Keep in mind that this will ONLY run on systems without Extended Color Basic, but it will work with 16K of RAM and up.
This has been tested on real hardware but you can also load it into an emulator like:
