Nope, I got totally stuck there. I'm playing on an NES using an N8 Pro. I made a savestate on the cart, I'm not sure how/if the game has battery save. If it does, I can see what happens when I start it up tonight.
I'll report back later tonight (like 10-12 hours from now) and let you know what I can find. I can send the savestate and battery save files as well, if you'd like.
