Tetris 2 (SNES)

Tetris 2: It's like Dr. Mario, but with tetrominoes instead of pills.

Debug menu
A debug menu can be accessed by starting the game with the PAR code (US version) or  (Japanese version).

The four options, in order: Two choices here are of particular interest: Both are detailed below.
 * GAME MODE: Selects from the various game modes (normal, puzzle, 1P vs. 2P, 1P vs. COM, etc.), as well as basically every other screen in the game, including high scores, win/loss screens, and the debug menu itself. Use Left/Right to select the screen of your choice (provided you have the ability to read Japanese), then press Start to go there.
 * デモ: a movie/cutscene viewer
 * パズル工ディット: a puzzle editor
 * COM SEL: Appears to select the computer opponent's skill level for 1P vs. COM mode.
 * CGX: A tile set viewer. Use Left/Right to select a tile set, then press Start to view it. While viewing, the B and A buttons cycle through the different available palettes, and Start returns to the menu.
 * MUSIC TEST: Self-explanatory.

Movie viewer
The movie viewer allows you to view the various "round clear" movies that occur throughout the game. Use Left/Right to select, then press A or Start to view it. The movie will loop until you press A or Start a second time. Press B to return to the menu.
