Pandora's Blocks, formerly DMGTRIS, 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.
