DMGTRIS, now renamed Pandora's Blocks, is an open-source homebrew game for the Game Boy inspired by the TGM series. The source code for the game is written in assembly and is available under the GPL-3.0 license.

Gameplay

Pandora's Blocks features mechanics largely based on the TGM series, including IRS (Initial Rotation System), IHS (Initial Hold System), and step reset lock delay. The game has a BIG mode, 20G option, and multiple choices for the randomizer, rotation system, and speed curve.

Randomizer

• TGM1
• TGM2
• TGM3
• HELL: Memoryless (completely random) randomizer.
• 1ROL: If a piece matches the previous piece, it is rerolled once, similar but not identical to the randomizer in Tetris (NES, Nintendo)

Rotation System

• ARS1: The Arika Rotation System used in TGM1 and TGM2
• ARS2: ARS with the changes introduced in TGM3 (additional kicks).
• SEGA: The rotation system used in Tetris (Sega, 1988)
• MYCO: ARS1 except that I pieces are allowed to kick and there is no center column restriction. The name refers to mycophobia, the developer who created this rotation system for version 1 of Tromi.

Speed Curve

• DMGT: Default endless speed curve
• TGM1
• TGM3
• DEAT: Based on T.A. Death mode from TAP
• SHIR: Based on Shirase mode from TGM3
• CHIL: Slower paced speed curve
• MYCO: Based on version 1 of Tromi.
