Overview
Happy New Year! Romhack Plaza, affiliate of FFV Central, kicks off 2026 with the debut of a graphical improvement patch by Terwilf for the controls overhaul for the Famicom version of Tetris.
Graphical improvements include the main menu, bootup screen, and ending fireworks. This was achieved by optimizing the storage of CHR data in the rom.
Original Announcement
Despite being the first Tetris game to land on a Nintendo system, Famicom Tetris is grossly unappreciated due to its unusual control scheme. This romhack updates the game to have the standard controls that players have come to expect from a classic Tetris game.
Features
- Hard drop (A button)—remapped to Up on the D-pad.
- Rotate counterclockwise (Down on D-pad)—remapped to B button.
- Soft drop—newly added; mapped to Down on D-pad.
- Rotate clockwise—newly added; mapped to A button.
- Bonus: exploit patched—holding down any button after a hard drop no longer stalls the game indefinitely.
For a demonstration of these features, see the video below.
Patching Instructions
First apply the base mechanics hack. Then optionally apply the graphical-improvement hack as desired.
