Thank you for this engine, it works really nicely! I only have one question about the wild double battles. On default configuration, all wild battles seem to be double battles. How would I go on about creating specific patches for double battles (like in BW) while retaining single battles in other areas?

Well, you'd need to code that. :P Preferably set up some table with ids for metatiles(like dark grass) that allow double battles and if the tile the player is currently walking on matches, the battle will be double.
Check out src/wild_encounters.c, line 597.

This engine does not provision for the SpDef boost Rock types gain during Sandstorm, nor does it flag Blizzard as 100% accurate during Hail.

How do I configure these?

Also, @DizzyEgg, what's the best way to get in touch with you to contribute? I feel like working on some move animations, wondering if I would just make a pull request when I'm done

You should do it by using git and merging, I will write a tutorial on that soon. Doing it otherwise...well that'd be like gluing without glue.

Does this mean you will do a merge guide at some point for your branches?

I noticed that there is a debug menu included with the engine. how would I go about using it? I assume I can open it as USE_BATTLE_DEBUG is forced true in battle_debug.h, I'm just confused as to how.

Anyone?

You edit the table here. https://github.com/DizzyEggg/pokeemerald/blob/battle_engine_v2/src/battle_message.c#L3546

The fields go: trainer id(use constants from constants/opponents.h), and 3 pointers to strings, they're displayed when last mon is brought out, when last mon is at low hp and when first pokemon is down respectively. If you want a trainer to have only 1 or two messages, instead of a pointer just put 0 or NULL there.

Press SELECT or START when choosing battle action(run/fight/pokemon/bag). When there, use L/R buttons to change between battlers.

2 questions:
1- where are the items stored? I found a file but it doesn't have the new items, only the old ones.
2- can I edit the mart items with this?

1. The item effects are defined in constants/hold_effects.h. The actual items are not present in the battle engine, you need to either add the new items yourself or use my item expansion repo that has all of them.
2. No, this is a project strictly for battles. My item expansion repo has all the items tho, and you can edit mart items with that.

Hi, a couple of questions.
Still new to decomp so apologies if the answers are obvious.

1: Are primal reversions or wish mega evolution currently included in the engine?
2: How feasable would it be to have different weather setting abilities set either temp or permanent weather. As an example; Allow Groudon to make permanent droughts but Ninetales/Torcoal only produce the 5-8 turn Drought like in Gen6 and beyond.

1. No, so far ony mega evo is coded.
2. Pretty easy, each weather has two flags WEATHER_X and WEATHER_X_PERMAMENT, so it's a matter of checking a pokemon species and if it's groudon set it to be permament, otherwise use regular 5-8 turns weather.
