pokefirered VS porymap

Definitely definitely look at doing your project as a decomp using pokefirered or The Complete Fire Red Upgrade.

Pokémon Ruby/Sapphire, Pokémon FireRed/LeafGreen and Pokémon Emerald.

The quickest way would be to edit the decompilation. All the graphics are stored there as separate files there allowing you to easily replace them.

The "Person ID" is what I was referring to in my previous reply. You should write the ID of a flag there. Then make sure the flag is cleared if you want the NPC to appear and make sure it's set if you want it to not appear. You can find a list of valid and unused flags here.

Or use the pokefirered source code decompilation project.

You will have to program those mechanics into the game. You can do that by using the pokefirered decompilation.

If you're just now trying to get into romhacking, the best thing to do is to check out the pokefirered decomp project here. I have the most up to date video tutorial series for the decomps, I use pokeemerald in my tutorials but a large part of everything is the same. We have access to the full decompiled source code, so it's really easy to make changes to whatever you want and the workflow is practically identical to what the actual Pokemon devs would have been doing, whereas binary hacking, the old outdated method, is its own entire thing.

Weird question but, how do games which are coded like pokemon work? https://github.com/pret/pokefirered/tree/master/src for example this disassembly in c. Seems like each component has its own file, like battle.c or trade.c etc. How do these components communicate with each other? How and where does the main gameloop run? I would be very glad to get more info and write something like this game on my own (each component in own file, not pokemon 2)) ), because I'm not good at game architecture and cant resolve this on my own. thx in advance

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!
