Heya! Wasn't sure if anyone here was aware, but there's a major exploit in this game that can be used for quick money. It's pretty unwieldy and you need the right setup, but maybe it could be used for Fog Cards or honeys more efficiently.
Basically if you Trade for your second+ item but don't have the money, the cursor gets put back wrong. You can scroll up past your first item into out of bounds memory and sell other stuff. This isn't where the game progression or chapter is stored, but you can sell unused memory for like 20,000 GP. You're also setting that address to 7 (Chapter 1) or 15 (Chapter 2+), so casually you could reset your LVL or get Dao in Chapter 2. But that also means if you don't count correctly, you could set your max HP to 7.
