pokeemerald VS pokefirered

When you start a new game, the game generates the Dewford phrases (and Feebas tile seeds) from EasyChat words by making some calls to RNG, shown here in InitDewfordTrend and SeedTrendRng. To summarize (assume H16 is the upper 16 bits of the RNG seed on that advancement): It makes a call on Advance x to determine the first word, always pulled from CONDITIONS (H16 % 69) It calls RNG on Advance x+1 to determine whether the second word is from LIFESTYLE or HOBBIES (H16 & 1, LIFESTYLE if it's 1, HOBBIES if it's 0) Then it calls RNG on Advance x+2 to determine what that word will be (H16 % 45 for LIFESTYLE, H16 % 54 for HOBBIES) It calls RNG on Advance x+3 to determine whether the trendiness is increasing or decreasing (not important for this, but it's H16 & 1) It calls RNG on advance x+4 to try setting the maximum trendiness If this value is greater than 50, it calls RNG again (on advance x+5) to try setting the max trendiness. If this value is greater than 80, it calls RNG a third time (on advance x+6) to set the max trendiness (each of these calls are H16 % 98) Once it has the max trendiness (takes the result from above and adds 30, giving a max value of 127), it calls RNG to set the current trendiness (the value itself isn't really important for our purpose, but it's (H16 % (max trendiness value+1)) +30, where the max trendiness value is the value before adding 30. This value also has a max of 127) Finally, it calls RNG to set the associated Feebas seed (H16)

it's used for working with decompilation projects like pokeemerald

This is the main one: https://github.com/pret/pokeemerald/wiki/Adding-new-event-object-or-overworld-sprites

I strongly recommend you to switch your project to pokeemerald as it's more difficult to get those bugs. Also you'll get some tutorials in its wiki.

There are several reverse engineering projects out there which perfectly reconstruct 1:1 accurate C code and compile to the exact same bytes given the original compiler. Please see https://github.com/pret/pokeemerald . Of course you lose names and comments but it is not accurate to say no to this question here. It's perfectly possible to construct recompilable matching C code (purely in this narrow case, anyway.), it's just really tedious and a question of permutation through sets of C fast enough to find a matching member.

You could start by looking at the decompositions like https://github.com/pret/pokeemerald and seeing what resources they have, but it’s gonna require coding and it’s not as drag and drop.

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

I don't know about any sort of translation, but if you're trying to do something specific, you generally try to think of a place in the vanilla game that already does it and check out its script file to see how it works. You can see all the event functions (or macros as they're called in the files) here: https://github.com/pret/pokeemerald/blob/master/asm/macros/event.inc

With enough dedicated people it doesn't have to be, https://github.com/pret/pokeemerald

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
