Dragon Quest V: Hand of the Heavenly Bride

Debug Room
Ac47pVVkk4k Use the following Action Replay code in the US version to access a Debug Room. Note that this room is a modified version of the Debug Room found in Dragon Quest IV for the Nintendo DS, a not-so-subtle hint the two games share the same engine.

It consists of a house interior with different floors, such as water, ice, and damaging floors. There is a healing spot, a raft and a freaking ship taking you to an "island" of sorts, and nonfunctional stairs. One of the ropes leads to an an upper floor, with a strangely shaped conveyor belt. Oh, and two locked doors.

There are also some pitfalls and a second rope, which would take you to an exterior area with loads of NPCs. Unfortunately, their functionality is disabled, but there is matching translated debug text in the ROM. You can wander out-bounds in this map for some reason. A well can take you back to the previous room.

Anti-Piracy
Should the game detect the player has a pirated copy, the game will loop the intro scene indefinitely.
