It's not actually done yet, but if anyone answers this post, I'll probably post it up. Much better (in my opinion) than the "Tetris 1.1" on TiCalc.org, because his has like 3 strings, and a picture variable, and its 11KB. 11KB! Mine right now, is 2KB, 2238 Bytes. It has 5 pieces, everything but the L shaped ones. It has line deleting, and the blocks fall after, in a cool animation way. And it has Line counter, "Next piece" box, and a score. When you lose, its pretty neat, it shows a nice animation. The only problems are, I haven't made it check if you're going into a piece when it goes left and right, and you can switch (press up) ANYWHERE. Like you can fit a ∇∇∇∇ piece into a space that has 3 places, by switching when its touching the ground. If anyone would like to see it, please respond to this post.
Edit: I forgot to ask, how do you add a picture to a post? Because if I can, i could probably take an animated GIF. Except I can't seem to find a good emulator, how do you get one that works? The stupid ROM picture requirement annoys me.
