Q: Is a No Battle/Encounter Hack possible?

My best thought to make the exploration more meaningful is to make the treasures into some sort of scoring system. For example, edit the text (also doable with the OP's skill level) to list a score, or assign a Gil Value to every treasure that represents how rare/valuable it is. For example, the Force Shield could be worth 20 000 Gil when sold, and a Genji Glove could be worth 10 000. It would be a lot less like Final Fantasy and more like Great Cave Offensive from Kirby Super Star, but it might spice it up a little if the player could get something at least, even if it's just bragging rights.
