In proposed2nd.qst, on screen 0x58 of the overworld there should be a Burn Trigger (any) on one of the trees, but there isn't. This is confirmed by:
- A map on GameFAQs
- The fact that the screen is set to a room type
- The fact that the yellow square is set to the tree shown on the above map.
This has not been verified on the NES or with a ROM, because I can't be arsed to play through the game far enough to verify.
EDIT: I swore that I posted this in the wrong place, so if someone fixed it for me, thanks!
Also, on screen 0x6D of Map 2, the Enemies->Item flag should be set, according to this video.
