Gyakuten Saiban: Yomigaeru Gyakuten Cheats (Nintendo DS)

Have the Game Boy Advance game Gyakuten Saiban in the cartridge slot.

During the Case 5 ending credits on the touch screen, fingerprint powder will be applied
and blown away to reveal the credits. Eventually, a dialogue scene with a character will
appear. Tap the touch screen at this time as though applying fingerprint powder to it and
blow it off (as done during the game) and a hidden drawing of that character will appear
on the top screen.
