atari2600land picked up the work on his bBasic Tetris game for A2600.

Release notes from atari2600land:

I don’t know why I quit working on this, but I did, and now I’m back to this again. I’d really like this to see a release, seeing as how Edtris is no longer available, and the Tetris clones seem to not be working on any more (Chetiry, NIRB). So what do I need to do next in order to make this releasable? By the way, I’m not going to have the blocks drop faster over time since there’s only 10 rows.
