I don't think the "file cabinet" game save system in "Dragon's Curse" works on the VC version of the game.
It does for a large portion of the duration of the game, but after a certain point:
You save your game to the File Cabinet
You reset the game
You load the game from the file cabinet
It remains the same as what the save state was until the certain point where it stops working!
Here is an example of what can happen:
You have 4000 coins when you load. You have 5000 coins when you next save. When you reset and load your game, your balance is back down to 4000!
