[Emerald] Making a Tag Battle Script

[Danny0317]

Everyone remembers the awesome scene in Emerald where the player and Steven beat Maxie and Tabitha in Mossdeep city, right? Well, it looks like not many people know how to make a script like that. Yesterday I figured out how.

Before I begin, I would like to give a huge thanks to Pia Carrot from PHO for starting a Steven research thread over on those forums – That's what got me to make this. Let's get started.

Making the Script

Yesterday, I went through Steven's script trying to figure out how it works, and I did. In there you can find everything I did to figure it out. To make a script like that, you must write something like this:

#dynamic 0xE40000
#org @start
lock
special 0x28
fadescreen 0x1
special 0x2A
waitstate
compare LASTRESULT 0x0
if 0x5 goto @yes
special 0x29
goto @end

#org @yes
special 0xFB
setvar 0x8004 0x2
setvar 0x8005 0x4
special 0xEA
setvar 0x8004 0x8
setvar 0x8005 0x0
special 0xEF
waitstate
setvar 0x8004 0x6
special 0xEA
special 0x29
copyvar 0x8000 LASTRESULT
compare 0x8000 0x1
if 0x1 goto @continue
fadescreen 0x1
special 0xCB
waitstate
goto @continue

#org @end
release
end

Editing Steven's, Maxie's, and Tabitha's Pokemon

Okay, so this one is a bit easier. To do this, download this and this.. Those two things are Nightmare Table Editor and Nightmare Table Editor modules for Pokemon Emerald. Huge thanks to Agastya for sending me Nightmare.

Now open the Nightmare Table Editor, and open the module that says something about Mossdeep and Steven. In there you get to change the level, movesets, EVs, species and more about Steven's Pokémon. Edit them as much as you want, and set them how you like. To edit Maxie's and Tabitha's Pokémon, open A-Trainer, or any other trainer editor and head to 0x202, which is Tabitha. Edit him as much as you want, then head to 0x2DE, which is Maxie. Edit those to you're liking, and you now have a fully-customized tag battle script!

I hope it was easy enough to understand for all of you, and if there are any questions, don't hesistate to ask.
Thanks to Alex for fixing up the grammar and other stuff. :)

This is very interesting, I've always wanted to do this? Unfortunately, this script won't work on Firered, right?

Very neat! However, does this mean that we can only make one Tag Team battle, as you said to edit Maxie and Tabitha's data? Or can this be applied to multiple battles throughout the game?

Sorry, but it's Emerald only D:

Honestly, I think that with a little bit of ASM it can probably be done more than once. :)

Hello, do you know how to find the Trainer ID 0x202 in hex editor to change to Trainer ID 0x2DE for the tag battle script?
