Battle of Kingdom English translation
バトルオブキングダム
Stardust Crusaders' short and complete English patch for the little-known Game Boy card strategy game Battle of Kingdom.
About the patch
Pennywise hacked the game and edited the text, with translation help from aishsha and Ryusui. The game has very little Japanese in it, so the job was small: version 1.0 came out in May 2017, and version 1.01 later translated a few more bits of text.
What's translated
The opening story, the card shop, the stage screens and the battle displays are all in English, so you can follow what each monster card does.
Playing it
Apply the patch to your own copy of the Japanese cartridge, following the readme on the project page.
