Yu-Gi-Oh! Nightmare Troubadour is a video game developed and published only for the Nintendo DS portable device by Japanese company Konami back in 2005, as another iteration based on the extremely popular Yu-Gi-Oh! anime franchise from its native Japan, with its story focusing on the Virtual World arc from the TV series.
Yu-Gi-Oh! Nightmare Troubadour still uses the same elements seen in previous games in the series up until that point, as players need to find and collect trading cards with different creatures on them, which are then used in battles against other opponents called duels, but also manages to introduce new things like a special control scheme that uses the Nintendo DS' unique features like its touchscreen or Wi-Fi connection.
CHEATS
Password Machine
Win the Expert Cup. The Password Machine can now be accessed in the Duel Shop by tapping the slot machine on the left. The Password Machine allows you to type in the ID number of a card you have and insert it into the game (for 1000 KC). Passwords will only work if you have obtained at least 80% of the pack it comes in (you have the card list) or the card is on your card list (total). You can only get one copy of a card, and no God cards.
