For the Frog the Bell Tolls Color
カエルの為に鐘は鳴る · For the Frog the Bell Tolls
A colorization patch that turns the English-translated For the Frog the Bell Tolls into a Game Boy Color game, with colored backgrounds, sprites, portraits and menus plus a redrawn font.
What it does
amosjerbi's patch turns the monochrome cartridge into a Game Boy Color enhanced game. Backgrounds, sprites, character portraits and menus all get color: green frogs and forests, a blue ice cave, purple dungeon stones and throne rooms, a red snake boss and a princess with yellow hair and a pink dress. It also adds a redrawn font for the dialogue, and the patched game still starts on an original Game Boy.
It is built on the English fan translation, so the text stays in English.
How it works
The patch switches the Game Boy Color into double-speed mode to handle the extra work, adjusts the sound timer so the music keeps its tempo, and keeps a palette for every graphics tile, derived from the game's own palettes so fades still work. The project was made with AI help; the repository even includes the workflow used to colorize the game.
Work in progress
Color is set per 8x8 tile, so a tile shared by two areas carries its color into both, and some animation frames are still unfinished. Version 12 adds new palettes and fixes many sprites.
Playing it
Apply the patch to your own copy of the game with the English translation already applied, following the instructions on the GitHub page, which names the exact version it expects. Play it in a Game Boy Color capable emulator or on real hardware.
