Oh, “brick game” like Tetris, I initially assumed “brick game” like Breakout.

This is very cool! I had one of these N-in-1 generic block game consoles when I was a kid. I was very surprised at the variety and surprisingly acceptable quality of all available games.

Sadly, the Brick Game model from which the ROM dump was taken doesn't contain a racing game, which was in the Brick Game that I had as a child.

I added Mac OS compatibility: https://github.com/ilyakurdyukov/brickgame-4bit/pull/1

I taught myself probably 5 languages making an ASCII version of Space Invaders way back in the day.

Do you have some screenshots?

Does it count as a screenshot?

Is this the first design of tetris?

I think not. There is not only Tetris, but also Snake, and two types of "shooters" - one removes blocks, the other creates. And many variations of these four basic games.
