Tetris - SNES Gravity

Hack of Tetris

Description:

NES and SNES are very similar in game mechanics. They obey the exact same auto-shift and delayed-auto-shift rules (this is referring to moving the pieces left and right). They also follow the same rules for each level’s fall/drop rate (the speed at which the pieces fall to the bottom of the screen). But there is one major difference between NES and SNES game mechanics.

While it is true that both games match each other in falling speed (the rate at which the piece falls to the bottom), there is a difference in the rules of gravity between the two games. In NES, gravity is in effect as soon as the next piece has been generated, while in SNES, gravity doesn’t kick in until ten frames of screen time have passed. That means that SNES gives you ten frames of game time in which the piece is “floating”–you can begin to move the piece left or right during this time, it’s active but not falling. NES does not give you any sort of “head start”–as soon as your piece appears, it is already falling.

Ten frames amounts to 1/6 of a second. The game displays 60 frames per second, and ten frames is 10 out of 60. That is a really big deal for the Tetris Master.

This patch adds the pre-gravity behaviour from the SNES version of Tetris (from “Tetris & Dr. Mario”) without affecting natural drop speeds of the NES release.

Also includes a version for the “Tetris Zero” hack.
