TetrisGYM is a modification of NES Tetris.

While originally based on the NTSC version of the game, the patched ROM supports PAL and NTSC gameplay types.

Some trainers have additional configuration values; use left and right in the main menu to change them.

Like in the original ROM, holding a b select and then pressing start will end gameplay and return to the menu screens.

This hack effectively changes the framerate of the NES, which allows for some very interesting speed options for Tetris.

This hack converted Tetris from MMC1 to MMC3 to take advantage of its *scanline counter*, which lets it schedule polls at arbitrary intervals with remarkable precision. To help facilitate this, the code was optimized by a factor of 3, now spending less than 10 percent of a frame actually executing logic compared to the original 30 percent.

Currently it can divide the frame into 6 equal parts without running into issues, which allows for plenty of speeds to experiment with, like 72hz (6/5), 100hz (5/3), and even 360hz (6/1) if you’re feeling adventurous.

Tools

:S27: Permanent Game Genie Tool :S27:
Does what it says… Patch and never worry about punching in letters again! Side note: Game Genie codes generally work on both PAL and NTSC versions of Tetris. An exception to this is the PAL 3-in-1 cart with Tetris, Mario, and World Cup. For this particular cart, all codes must be modified to work with it. Using this site, input the original code, take the address and subtract 3 (in hexadecimal) and hit return to get a new code that will work. One last thing; it’s not a hack but it’s definitely a useful tool: 

:S05: fridaywitch’s DAS Guide :S05:
An 8-page guide that explains DAS in such a way that should be easy to understand. DAS Guide 

:S21: E_flat’s Tetris Block Tool :S21:
With the Block Tool, you can draw specific boards with editable next piece, score, and statistics. Use the Block Tool to describe situations you just can’t put into words! With the Board Tool, you can generate and draw on random boards with a current piece and next piece. Use the Board Tool to practice stacking by finding the best moves with the pieces you get! 

Patches

We’ve compiled a list of most patches and game genie codes released for NES Tetris. Patches mostly come in .ips files; to use these, you’ll need to patch your legally-acquired Tetris game using one of these programs:
