After I went through them, I realized that R,S and E haven't the same loacation name table like FR and LG. The location name in R and S were started with Littleroot Town and ended with Secret Base. I found nothing with Pallet Town and so on. And I found out Pallet Town in E but it was located at the middle of the pointers of the text of location name which at 0x5A1738. Its entry (0x58) was same as the FR and it ends with Pattern Bush. Then I can't found anything about Celadon Dpt. again. The same table in LG at 0x3F1AE8.
PS: Referred to this website:
https://bulbapedia.bulbagarden.net/wiki/List_of_locations_by_index_number_(GBA), it explained that: Locations with index numbers up to 087 appeared in Pokémon Ruby and Sapphire, those with index numbers between 088 and 196 appeared in Pokémon FireRed and LeafGreen, and those with index numbers beyond 197 are exclusive to Pokémon Emerald.
