Expand the Town Map tileset Alternate
Note: You should not follow this tutorial and the main one! Pick one.
This is an alternative tutorial on how to expand the Town Map's tileset. It has more changes but allows you to keep the Pokégear and Town Map images separate and keeps the Pokégear tiles from being loaded when they don't need to be. This tutorial supports only adding another 32 tiles. If you need any more, follow the main tutorial.
The main tutorial is less involved, however doesn't allow for the Pokégear and Town Map separation like in this tutorial.
- Move text out of the way
- Replace tile IDs
- Add two rows of palettes
- Fix the Pokégear tilemaps
- Fix the Pokédex
- Create your own Town Map
Follow steps 1-5, 9 and 10 of Expand tilesets from 192 to 255 tiles to move usable text from the bottom left part of VRAM. Skip if you've already done it.

Edit gfx/pokegear/clock.tilemap.rle and replace its contents with:
6F 08 6F 04 50 01 7F 06 51 01 6F 08 6F 04 7F 08 6F 0C 52 01

7F 0E 16 01 6F 02 6F 02 26 01 07 0E 27 01 6F 02 6F 14 FF
Then edit gfx/pokegear/radio.tilemap.rle:

Replace gfx/pokegear/town_map.png with the file below, or a new image with new tiles. Keep it 128x40 with border tiles in the same place as the ones below.
Edit engine/pokedex/pokedex.asm:
DexEntryScreen_MenuActionJumptable:
...
.Area:
...
predef Pokedex_GetArea
call Pokedex_BlackOutBG
+ call Pokedex_LoadGFX
+ call Pokedex_LoadAnyFootprint
That will fix the tiles not being right when exiting the map.
Then, edit gfx/pokegear/johto.bin and gfx/pokegear/kanto.bin following the Edit the Town Map tutorial.
