I just updated the main project picture. I'm drawing multiple mushrooms and the nameless trademarked bugs.

900 bytes used. It's getting tight.

The video loop is using an old Atari 2600 trick: The even frames show mushrooms and the odd frames show bugs.

Now I need to squish the game logic of the bugs moving around the mushrooms, and shooting them down, in very tiny space. I suspect I'll have to rewrite the video driver loop to be smaller somehow.

Here is a pic of the whole hardware setup.
