I turned on the spot since I thought the guard was done talking, and either it's an emulator glitch or frame perfect, but he's still talking about Sludge Bomb. I presume it's either well known or not useful enough to make a difference, but still not something I expected to be able to do!

That run is exactly the reason I created an account here. XD

I put together a few maps showing the sixteen possible maplets the game can put into (at least?) the 4x4 grid, with trainer sights marked on the second in red.

I've always wondered how easily this could be done, so I'd love to see and help this develop further!
