Tetris: Tetris - Max Speed

Tetris - Max Speed is a demonstration of the maximum speeds Nintendo could have used on Game Boy Tetris. This is for informational purposes; as well as for possible Tool Assisted testing. And if someone just wants their endless Tetris experience to have an endgame... well, that works too.

Level 7 in this corresponds to Level 20 in the original. Level 8 in this is theoretically playable. Level 9 is not playable, even with tool assistance.
(This mod skips directly to the final 10 speed levels, no "Heart Mode" (UP+Start) code needed.)


What follows is a quick rundown on the exact speed each level is in the original, and then in this mod. The speed is how many frames (out of 60) the game waits in between the piece falling each row. This has been converted into milliseconds. Therefore a lower number means the gameplay is faster, and a higher number means the gameplay is slower.

Interestingly, in the original game, levels 14 & 15 were the same speed. As were 16 & 17 and 18 & 19.

(Level 09 and beyond have NO wait in between pieces.)


This mod is for the more common 1.1 version of Gameboy Tetris.

There are 2 additional patches for converting other mods to Tetris - Max Speed.

"Tetris - Max Speed - Hard Drop" is specifically for https://www.romhacking.net/hacks/5125/. (Use this patch second, on the already patched Tetris - Hard Drop.)


"Tetris - Max Speed - Rosy Retrospection" is specifically for https://www.romhacking.net/hacks/5813/. (Use this patch second, on the already patched Tetris - Rosy Retrospection.)

[Because Rosy has a built in delay between pieces to make the game easier, this one is actually quite playable at max speed.]
