This is a large-scale compression of KEP's current hide/show constants. RBY's works extremely oddly and is limited to 256 entries.
The problem with how RBY's hide/show stuff works, is that even though there are tons of unused constants, you...can't actually remove them. The constant list is tied to the hide/show data entries, so if you replace it with something else, well, now you just have two objects tied to the same constant. If you made the Route 2 item a boss, and someone picked up the item on Route 2, the boss would also disappear, and vice versa. So, we have to get creative.
I have reduced what we have to 248, but I think I miscounted when doing the funny list somewhere in the actual list when making sure the hex stuff is ok. Either that, or there's an error somewhere that Martha will, by some obscene miracle of humanity, discover. Anyway, this was achieved by turning multiple current overworld items into hidden ones, keeping them in the game whilst keeping to that all-important limit.
I also removed the items in Pokemon Tower 4F for this, just needed a little boost. Well, as you can see by the number, I technically didn't, I just miscounted like 20 times. Look, it's 10:11 PM, my stomach is in pain from an insane injection, and I don't even know if that map will come back, cut me some slack. Or add it back. You definitely can.
The warp at the moment is an absolute travesty, something on that tileset needs to change. Either that or we figure out something else.
Everything in the Grotto is done, except for making Galarian Zapdos disappear after being defeated. At least, to my knowledge...
Pokemon Tower 3F is dead until future notice - Martha said she wanted to compress the Diglett's Cave maps, though.
* Update sign to bg_event #289
