 The odds of encountering a shiny Pokémon in Gen 2 are 1 in 8,192. That value isn't literally defined anywhere: it's a consequence of making shininess based on DVs. A shiny Pokémon has:

+There are eight palettes used for tilesets: `GRAY`, `RED`, `GREEN`, `WATER`, `YELLOW`, `BROWN`, `ROOF`, and `TEXT`. It's called `WATER` instead of `BLUE` because its lightest hue gets animated for some tilesets, cycling between three colors. This makes water (and rocks, whirlpools, and waterfalls) look more dynamic, but it prevents you from making static blue tiles (like Mart roofs).

+To stop it, edit [engine/tilesets/tileset_anims.asm](../blob/master/engine/tilesets/tileset_anims.asm) and replace all the instances of `dw NULL, AnimateWaterPalette` with `dw NULL, WaitTileAnimation`.

 If you simply lowercase all the names in [data/pokemon/names.asm](../blob/master/data/pokemon/names.asm) and rebuild the ROM, the first letter of their names may be missing. The cause is changing "`FARFETCH'D`" to "`Farfetch'd`", because "`'d`" is actually a single character. The fix is to pad its name to the same length as all the rest with an "`@`", so that it becomes "`Farfetch'd@`".
