Dragon Warrior 1 - Platform: Gameboy Color

Betray the kingdom
------------------
Rescue the Princess before you fight the Dracolord. Take her with 
you to the final battle and the Dracolord will ask for her. You 
have now have the choice of answering "Yes" or "No" to his request.

Easy money
----------
Find a place that sell repellent for 12 gold. They will pay you19 
gold if you sell it to them, or anyone else that buys items from you. 
Buy as many repellents as you can, then sell them to someone. Buy, 
then sell, and repeat. 

Go to the place that sells keys for 16 gold, then exit and re-enter. 
Sell them at a weapons shop for 26 gold, which is a larger profit 
than the repellent trick.

Changes from NES version
------------------------
The legendary hero is named Loto instead of Erdrick. 
The game is much easier in the Game Boy Color version. 
Princess is named Lora instead of Gwaelin. 
The keys were called Magic keys in the NES version. 
The main villain is called Dracolord instead of Dragonlord (hence 
Dragon Warrior). 
Stairs required you to select a menu option to ascend/descend in 
the NES version. 
The battle messages have been shortened significantly. 
The world map has shrunken . 
50 instead of 100 levels. 
Enemy names have been changed (for example, Drakee to Dracky, 
Metal Slime to Metaly). 
The enemies are now much easier to defeat. 
The town of Brecconary was changed to Tantagel. 
The Game Boy Color version reveals the King's name (Lars) in the 
Game Boy Color versionm but not the original. 
Powder Puff message added in Kol. 
In the NES version, if you choose to join Dragonlord you are put to 
sleep and you get a game over. In the Game Boy Color version, you 
awaken at Rimuldar. Also in the Game Boy Color version, he offers you 
half the world; in the original, he merely asks you to join him.
