Pokemon Fire Red map sizes and tile information

I'm new here, but I've been checking the hacking sections for about two months now. I've learned so much because of you that I decided to contribute myself.

First, I've gathered data on the sizes of the existing maps.
This information may be useful for those who want to save space, and replace an old map with the needed size for their new one.

Configuration -> map number: width x height
Bank 0 - linking corner(5 total)

bank 1 - caves, forests and important buildings (123 total)

bank 2 - trainer tower, lost cave, navel rock and similar maps (60 total)

bank 3 - towns and routes (66 total)

bank 4 - Pallet Town Buildings (4 total)

bank 5 - Viridian City Buildings (6 total)

bank 6 - Pewter City Buildings (8 total)

bank 7 - Cerulean City Buildings (10 total)

bank 8 - Lavander Town Buildings (6 total)

bank 9 - Vermilion City Buildings (8 total)

bank 10 - Celadon City Buildings (20 total)

bank 11 - Fuschia City Buildings (10 total)

bank 12 - Cinnabar Island Buildings (8 total)

bank 13 - Indigo Plateau Pokecenter/ pokemart

bank 14 - Saffron City Buildings (10 total)

banks 15 to 30 contain each 3 to 1 map, all houses on routes

bank 31 - houses and harbor on seven island

bank 32 - houses and harbor on one island

bank 33 - houses and harbor on two island

bank 34 - houses on three island

bank 35 - houses and harbor on four island

bank 36 - houses and harbor on five island

bank 37 - houses and harbor on six island

banks 38 to 42 contain 1 map each except for bank 41, with two maps



Also, i have information on the tiles behaviour bytes. I'll post only about the ones not yet present on AdvanceMap.


The background bytes seem to be cummulative.
1 : can encounter pokemon from grass
2 : can encounter pokemon from water
1 and 2 are mutually exclusive, so 3 has no effect.
20: the hero covers the block upper layer
Sum the bits and
21 : hero covers block upper layer && can encounter pokemon from grass offset
22 : hero covers block upper layer && can encounter pokemon from water offset

To end, here's the contents of each tileset. Where there is a ??? it means I couldn't find anything compreensible on that tileset
Configuration -> tileset number : content


I hope you find this useful.

Well somebody did their homework :)
This will be nice as a reference although I'm not sure that a lot of other people will find this very useful. Still, you can take solace in the fact that I will use it^^
Nice job! :)
