Fixed to work with newer builds. Included the main fix as a new step since it doesn't exactly fit anywhere.

 *Now* we're done! `make` works, and all the maps look the same as before—but now they're capable of looking very different.
 
 The pokecrystal map engine didn't support flipped, recolored, or priority tiles, so of course the tileset graphics were not designed to take advantage of those features. But now you can. And all of those engine features *did* exist in Gen 3, so if you're devamping tiles from RSE or FRLG, they'll benefit from this change.

 If you were paying attention during the review of how VRAM works, you'll have noticed that technically a map can use 512 different tiles. The tile ID goes from 0 to 255, and the bank bit is 0 or 1; 256 × 2 = 512.
