Debug Menu

Download Revelations: The Demon Slayer (Debug Patch) File: revelations-debug.zip (2 KB) (info)

The Game Boy Color versions contain a debug menu which was originally accessible by pressing Start during normal gameplay. The final version of the game still contains the debug menu, and still checks if Start was pressed, but the actual call to the debug menu was removed, meaning nothing actually happens when the button is pressed. Applying the above patch to either the US or Japanese GBC versions of the game will restore the menu to its original functionality.

Along with the four individual debug options, the top row of text also shows the current map number and coordinates.

• Map Move: Allows you to warp to any map at any coordinates, and also displays the current map number and coordinates similarly to the main debug menu. The number of maps you can access goes all the way from 0 to 255, but the game doesn't actually prevent you from warping to an invalid map, and doing so will crash the game.
• Battle: Lets you preview various battle sprites and animations. Up/Down and B select an enemy sprite to display, and Left/Right and A select and play an attack animation. Pressing Start from here completely exits the debug menu and returns to the game.
• Chara: Displays overworld sprites. Left/Right and A select a character sprite to view, Select changes the direction the character is facing, and B returns to the main menu.
• Flag: Displays/edits the values of various in-game flags. Use the D-Pad to increase/decrease the currently selected flag by 1 or 10, and press A to toggle the selected flag on/off or B to return to the main menu.
