[Map] Adding FRLG Tilesets to Emerald

[The Conqueror]

What the title says. I am unaware how to import tiles using porymap/the decomps. I'd like to add the FRLG tilesets to it is all. Any good tutorials on how to do this?

Just so we're clear, you won't be able to copy-paste tilesets from FRLG over to Emerald without modifying the functions of code related to how the game reads tilesets.
The tilesets in Emerald and FRLG are formatted differently after all.

That being said, if you're interested in creating a new tileset for Emerald using FRLG tiles, have you tried checking the Decomp & Disassembly Tutorials & Resources Section?
There's a tutorial about inserting tiles written by Lyzo.

I didn't try it, but it looks pretty thorough at a glance.
