I agree. It seems like interpreting one instruction per frame is the developer's way to guarantee real-time performance. I don't want to discourage the developer from experimenting with this design. What I think they should do is determine the most instructions they can interpret each frame.

I like the idea of on-device programming like this. While I haven't used it, I know there is a DSiWare application Petit Computer that lets you implement more complex (sprite-based) games in a Basic dialect: https://en.wikipedia.org/wiki/Petit_Computer. As DSiWare, it has an official video trailer: https://www.youtube.com/watch?v=4AYlEo3rJHs.
