A player can release and tap left or right, and after ARE is over, the counter's value will not change. During ARE, the DAS counter effectively freezes. There are a few other very interesting details. In effect, pressing and holding down the left button will first move the piece 1 column, then after 16 frames it moves another column, then it will move a column every 6 frames. After the left or right button is released, and left or right is pressed again, the counter will reset all the way back to zero. After 6 more frames, it will reach 16, the piece will move another column, and the counter will reset back to 10. Only, it doesn't actually reset all the way back to 0. This is called the 'DAS counter.' After holding down left or right for 16 frames, the piece moves left or right by one column, and the DAS counter resets.
The game keeps a hidden count of how many frames the left or right button has been held down for. Lock delay, wall kick, and hard drop are not present.ĭespite the title's popularity, its DAS mechanics were not well-understood until player Kitaru analyzed its internal memory values. The rotation system used in this game is a right-handed Nintendo Rotation System. The Nintendo Entertainment System is specified to run at 60.0988 frames per second.
