“Tetris - Rosy Retrospection” aims to combine the joyful nostalgia of playing classic GameBoy Tetris with the established comfort of modern gameplay mechanics.

This hack is published as patches in BDF and UPS format for the original game. You don’t need to apply both, just choose the format that’s more convenient for you to use.

For UPS, there is a great browser app at https://www.romhacking.net/patch/.
