Could you Closed Captioning in homebrew?

[S1500]

Here's a goofy idea that was on my mind for a while.

 

Could you, in a homebrew cart(any system) pipe out close captioning data?

 

Imagine the crazy possibilities if you could. Instead of using the resident graphics engine to display the score, use the closed captioning built into the TV to do it instead.

 

Go crazy and have a text adventure that uses only the CC text to render it.

 

I wonder if you could do it on an Atari 2600.

 

I'd love to see it.

Discussed a while ago - basically nope.
