All Working Vandal Hearts Cheats - Sega Saturn

Nova Key
After killing the Death Ant in the dunes, talk to the woman in the tavern and she will give you the Nova Key.

Earth Key
Talk to the young man in the tavern at Yuzu. He will tell you that he dropped a weird fruit in a plus sign bog. Pick it up and give it to him. You will then receive the Earth Key.

Chaos Key
To get the Chaos Key, you need three items: the Macroman, Tarot Card, and the Ramen. The Macroman is found in the northwest corner of Ygdra Canaon. The Tarot Card is found at Basil Gate in the southeast corner -- there is an X made of grass there. The Ramen is in the grate on the front car on The Magical Train. Go to Kerachi Village, go to the tavern, and talk to the collector.

Heaven Key
With all five keys, talk to the weird man in Glasgow City. He will give you the Heaven Key.
