Madou Monogatari I: Mittsu no Madoukyuu English translation
魔導物語I 3つの魔導球 · Madou Monogatari I: 3-Tsu no Madoukyuu · Sorcery Saga I: 3 Magic Spheres
The English translation of Arle's first Game Gear dungeon crawl, with a later fix so the text also reads properly on real hardware.
What's translated
The patch puts the dialogue, menus and battle messages into English, with a variable-width font so the text fits the small screen. It also carries a fix for the original game's compass behaviour.
Who made it
Filler translated the script and Kingofcrusher did the hacking, with the compass fix by Sfon; the patch first appeared in September 2010. In 2020 Supper released a separate add-on that fixes text that was unreadable on a real Game Gear.
Playing it
Apply the patch to your own copy of the Japanese cartridge, following the instructions on Filler's project page, which links the release page. If you play on real hardware, add Supper's hardware fix too.
