Yu-Gi-Oh! Duel Monsters English translation
遊☆戯☆王デュエルモンスターズ
An English translation of the very first Yu-Gi-Oh! game, Konami's 1998 Game Boy card duelling game that stayed in Japan.
What it is
Before the card game took over the world, Konami's first Yu-Gi-Oh! title was a Game Boy game about collecting monster cards and duelling the manga's cast. Darrman's patch puts the game into English so the cards, the menus and the duels can be followed without Japanese. It is listed as fully playable.
Playing it
Apply the patch to your own copy of the Japanese cartridge, following the instructions that come with it. The official page is the patch's entry on romhacking.net.
The translation is by Darrman.
