'''''Tetris DX''''' is a Game Boy Color game that enhances Nintendo's original [[Tetris (Game Boy)|Game Boy Tetris]], with three new gameplay modes, a profile/save feature, and color graphics when played on Game Boy Color and later systems. The game's [[rotation system]] has a glitch which lets players move any [[tetromino]], except the O-piece, upward by holding the direction against a wall and rotating in the opposite direction. | |||

Gameplay data is recorded and stored as "POWER". Each profile has its own POWER data. Using a link cable, this data can be transferred to another cart. | |||
In VS. COM, this can be used to play vs a CPU against a local profile, or a transfered profile's game data. | |||
Your power increases as you play better games using your profile. | |||

The rotation system is an early version of what would become [[SRS]]. | |||
Like in SRS, tetrominoes of width 3 rotate as if in a bounding square; unlike in SRS, L, J, and T start flat side up. | |||
TDX first tries rotation about the center of the box (the blue circle). | |||
If this fails, it tries rotation about an alternate center displaced by one cell (the gray circle). | |||
For I, S, and Z, this center starts out one cell above the ordinary center; for L, J, or T, it starts out one cell below. | |||

Tetris DX is a Game Boy Color game that enhances Nintendo's original Game Boy Tetris, with three new gameplay modes, a profile/save feature, and color graphics when played on Game Boy Color and later systems. The game's rotation system has a glitch which lets players move any tetromino, except the O-piece, upward by holding the direction against a wall and rotating in the opposite direction.

Power
Gameplay data is recorded and stored as "POWER". Each profile has its own POWER data. Using a link cable, this data can be transferred to another cart.
In VS. COM, this can be used to play vs a CPU against a local profile, or a transfered profile's game data.
Your power increases as you play better games using your profile.
Rotation system
The rotation system is an early version of what would become SRS. Like in SRS, tetrominoes of width 3 rotate as if in a bounding square; unlike in SRS, L, J, and T start flat side up. TDX first tries rotation about the center of the box (the blue circle). If this fails, it tries rotation about an alternate center displaced by one cell (the gray circle). For I, S, and Z, this center starts out one cell above the ordinary center; for L, J, or T, it starts out one cell below.
Wall climbing
This rotation system is exploitable, especially on low levels:
Charge DAS |
Rotate left |
Shift left (DAS) |
Rotate right about |
This particular exploit was fixed in SRS.
Infinity
Ordinarily, Tetris DX lock delay follows step reset behavior: only downward motion under gravity resets the lock delay timer. But rotation about the alternate center does reset the timer used for gravity. This can be exploited by placing a piece in a corner and rotating it back and forth about the alternate center:
Other gameplay notes
Scoring uses the Nintendo system, however the score multiplier is capped at 21 (25200 per Tetris).
Timings:
- DAS: 9 frames startup, 3 frames repeat.
- Lock delay: 32 frames or (frames per row + 4), whichever is larger.
- ARE: equal to lock delay, can be cancelled.
- Line clear delay: 50 frames.
