UndeadPeopleTileset VS porymap

There's a community maintained fork of UndeadPeople, so it's not completely abandoned/outdated.

When you download the undead people tileset (the new one) it comes with a folder for mods support.

This one: https://github.com/Theawesomeboophis/UndeadPeopleTileset

Yeah, still pretty active, though not the most active tileset anymore. I think they are currently trying to incorporate the whole new variant system for items. This is the most current version of it, as far as I know. https://github.com/Theawesomeboophis/UndeadPeopleTileset

Undead People is under new ownership and is regularly updated, but it's no longer included in the launcher so you have to download and install it from GitHub yourself.

Don't forget there is an updated fork of Undead people. It looks great and covers almost everything. It even has additional graphics for mods

This is undead people. It's being maintained here

If you don't want to code, Porymap is an incredible tool for making custom maps and changing Pokemon encounters.

Seems doable, yeah, especially if you have at least basic C knowledge. If you get the build tools set up, there's already some follower code available, so you wouldn't even have to re-engineer that yourself. And PoryMap can probably handle a lot of the basic edits you want to make.

You can look at the pokeemerald decomp. Instead of using binary tools like Adcance Map and HMA you are editing the source code with a simple text editor and porymap. The pokeemerald has everything up to gen8 (mons, moves, abilities). An example hack that was made with the decomp is Inclement Emerald.

Porymap is the best gen 3 map editor tool, but like the other replies imply it's for decomp hacking only.

decomp has an equivalent to advance map called porymap. it's really not all that different to use. i checked your post history and you mention having trouble with adding new tiles in advance map, i can say from personal experience that adding new tiles in porymap is very easy.

the other option i can think of is the pokemon emerald decomp. you would have to learn a bit to get a decomp working, then use pokeemerald-expansion's pokemon_expansion branch as a base. once you have that decomp set up you could just use porymap to change wild pokemon locations and make those pokemon available in the wild.

porymap!
