I know that name rings a bell.
I know you've owned one of these:

In your childhood.

"9999 games. you'll Never be bored."
And... 2/3 of it are Tetris.

I just bought one for myself, and was wondering if it was possible to program it.
I don't know that kinda stuff yet, so do think it's possible to emulate the above in p-8?

Sorry if the above was aggressive;

Getting exactly the same code might be hard. However, making a pico-8 cartridge that mimics the same look and feel would be pretty easy. It's a 10x20 field of squares in black and white with some text on the side. If you just make a 6x6 pixel square image with 2 colors and keep track of a 10x20 grid, you'll have the look down. From there the different speed settings can be handled by having a counter that can count up by different amounts, resetting and updating the game state whenever reaching a set number.

ok. Thank you!
