Dragon Warrior I & II (Game Boy)

Dragon Warrior I & II is a souped-up compilation of the first two games.

Debug Menu
r2D2DxV1dAI A debug menu still exists in the game. It has warp, party edit, sound test and sprite viewing options, among other things. This debug menu has the same setup as Lodoss-tou Senki: Eiyuu Kishiden, Bakuchou Retrieve Master and Command Master.

Enable it with the code (works with both Japanese and US versions). It will show up immediately after starting. If used on the US ROM, only some of it is legible since the Japanese wasn't translated, and Japanese characters show up as garbage.

Message Debug


Game Genie code will start the game in a Message Debug menu different than the one available in the standard debug menu.

Unused Super Game Boy Function
PAL_PRI. When bit set to automatically switches to the software's custom palette if any palette or its settings are altered. The Super Game Boy palettes are disabled, thus you never see the custom palette. TOSE could have originally intended to simply have the palettes switch back as done with Donkey Kong Land and other games. The Game Genie code will enable palette selection.
