Here in this tutorial we will increase the cap for metatiles from 1024 to 4096 by removing the redundant collision bit and decreasing the possible elevations from 16 to 8. You can also get 2048 metatiles with just the unused collision bit, without affecting elevation, the process would be largely the same as described here with some small changes:
## Description:
## Why Would I Want This:
Increasing the metatile cap is pretty self explanatory for some but many people have asked exactly what that means for them so I will be clear here for anyone confused, skip if you understand already. Normally when you're creating a map you have access to 512 metatiles from each tileset (in pokeemerald at least) adding up to 1024 total metatiles you can use. Metatiles are the 16x16 tiles that you actually place down in porymap, made up of 3 layers of 4 8x8 tiles from the actual tileset image. This does not increase the size of the tileset, but it does quadruple the number of metatiles that you can create using your tileset which is probably more than you will ever need. Before you could use 512 metatiles per tileset, after these changes you can use 2048.
