Thanks to a mistyped directory in my VBA config, I noticed something. When the King tells you that your game has been saved (or your quest recorded, to be accurate) in the GBC remake of Dragon Warrior, he's lying through his teeth. The game doesn't actually get saved until after you respond to the question of whether or not you intend to keep playing. What is the significance of this? Absolutely nothing, but since random bits of information are the foundation upon which ROM hacking is built, I figured I'd pass it along.
I was going to test out the NES version to see if the same thing happens there, but then I remembered that I'm lazy.
