Research: Pokémon Emerald Special and Special2 Commands (Fire Red As Well)

Sky High said:

Can you also list the specials which are empty, unused, or useless? I'm personally translating out JPAN's FireRed Hacked Engine's specials to Emerald. I got two specials translated but I dunno which special I will use for that so that is why I'm asking empty slots (noted that I knew where the table is).



Thanks! I can now finally test my personal translations. XD

EDIT: Can be the special table expandable? Will it be having limiter stuff?

Of course it's expandable. You'll have to change two routines (max) if there are limiters. However there is little point in expanding it. First reason I have for this is that there are countless nops - you can just replace those without fear of breaking anything. There should be more than enough. Second reason is that it wastes space - you'd have to repoint the entire special table to do this. Why not repoint the script command table instead (or replace a nop there)? It would waste less space and allow better functionality than specials...

I see. So, you suggest me to use the script command table than specials table. Hmm. Ok. Well, I just want to know the table location, and how will Jpan's special routines will work there (actually, I know how to use and insert commands as I have gone to battle string loader hack). Tutor me dude. :)

This is getting a bit off-topic so you might want to join #rhm on the IRC if you have more questions. The script tables are labelled in both of the IDBs in my signature, so check there if you need to find them. The routines that read the script table have limiters in the form of a pointer to the last command, so it should be quite easy to change and repoint this table. Script routines take a pointer to the script environment as their sole argument and return a boolean indicating whether they still need to do work or not. The reading of parameters is all handled by the commands routine, so you can have variadic commands too if you wish. Obviously this would mean rewriting JPAN's routines to accept script parameters instead of variables. You would also need a script editor that can handle modified script tables and configure it appropriately (Red Alien). If you need example routines, check either IDB and read through some of the script command routines. Most of them are fairly simple.

Is this worth looking into?

So I've come to the conclusion that the Emerald special table list isn't really well-documented other than the post below this one by my close friend Danny

So since I'm more technical, as are most of my other friends, I've decided to open up this thread since we're hopping on the Emerald train anyway. Toot toot here we go:

Formatting Codes -

Spoiler:

JPAN Documentation from http://www.pokecommunity.com/showthread.php?t=184273

Format is special number, whether it requires "special" or "special2", and the Fire Red equivalent.

Spoiler:

0x0 (Special) [0x0] ~ Heals player's Pokémon party silently
0x1 (???) [0x1] ~ Does something with player facing and location
0x2 (Special) [0x2] ~ Door warp script (fade black until finished warping)
0x3 (Special) [0x3] ~ Same screen effect as 02. Peculiar behaviour, warps to last used warp, or to center-map if last change was made by a screen transition, or trapped in Battle link if used after game start (I'm assuming this is map 0.0 he's talking about, so it could be Petalburg City for Emerald)
0x4 (Special) [0x4] ~

Spoiler:

Updates the value in 02031DBC by analyzing the data from the party copy at (03005008)+0x38
Notes - 02031DBC is var 8004 in Fire Red, the equivalent of this in Emerald is 020375E0.
03005008 in Fire Red is 03005D8C in Emerald, AKA, save block 1.

0x5 (Special) [0x5] ~

Spoiler:

Places a pointer to a function for posterior execution to 03000e84. The weird part is that that function only kills itself, erasing the content of 03000e84.
Notes - Not sure where he got 03000E84 from, it loads 03000E89. In Emerald, it's 03000E19
The function is link-related, it probably kills itself because there's no linking to be done.

0x92 (Special) [0x8F] ~ Gets the player's X coordinate and stores it in var 0x8004, and the Y coordinate in 0x8005

It's super late right now, of course this isn't the end of the list. I'll be updating as I go.

Better than my shitty list, LOL XD
But cool, really good to see this :)

Don't quote me on this, but I think special 0x1 is Emerald's equivalent of special 0x8F in FireRed. (08f Returns the player map position, the X to 0x8004 and the y to 0x8005. Coordinates are the same as the ones for the map in AdvanceMap.)

[15:26:07] <SphericalIce> fr's 8f is this:
[15:26:08] <SphericalIce> 10 B5 82 B0 EE F7 28 FB 6C 46 68 46 FE F7 C2 FE 68 46 00 21 40 5E 02 22 A1 5E EA F7 67 FF 08 4C 20 1C 69 46 FF F7 BE FD 01 1C 09 06 09 16 20 1C 6A 46 FF F7 C9 FD 00 20 02 B0 10 BC 02 BC 08 47
[15:26:16] <SphericalIce> em's 01 is this:
[15:26:17] <SphericalIce> 10 B5 82 B0 EE F7 CA FC 6C 46 68 46 FE F7 58 FF 68 46 00 21 40 5E 02 22 A1 5E EA F7 F1 FF 08 4C 20 1C 69 46 FF F7 D4 FD 01 1C 09 06 09 16 20 1C 6A 46 FF F7 DF FD 00 20 02 B0 10 BC 02 BC 08 47
[15:26:23] <SphericalIce> it's almost definitely the same thing

Special 0x92 in Emerald already does that, and 0x1 is the same between engines. I don't remember exactly what I saw it doing, but I'm assuming we should look into 0x1 since it may be good for scripting like 0x8F and 0x92 are

What happened to taking over this thread and expanding on the specials?

Anyways posting for anyone in general .... trying to figure out special 0x3E.

It's used in a script to allow for custom trainer battle music in battle without ASM in this example:

#dynamic 0x9C0B20

#org @start
lock
faceplayer
checkflag 0x???? // *Has this trainer been beaten?
if 0x1 goto @nobattle
playsong 0x??? 0x0 // Trainer's intro theme.
msgbox @intro MSG_KEEPOPEN // You'll need to put this here, or the battle will start with no intro.
special 0x3E // Special that makes a default battle happen. Required.
playsong 0x??? 0x0 // What song you want during battle.
trainerbattle 0x0 0x??? 0x0 @intro @defeated
setflag 0x???? // *Trainer has been beaten.
release
end

#org @nobattle
msgbox @afterward MSG_KEEPOPEN
release
end

#org @intro
= Hi there. I can beat you. Easily.

#org @defeated
= You just killed me bro!

#org @afterward
= See you around. My team's wasted...

If you test it out, after battle your Pokemon team is gone. You have 0 pokemon after the battle. I'm sure this is simply because it is putting your team to some var or something to be called later but by what? I tried looking for any script in Hex Editor but only came up with two occurrences of "special 0x3E waitstate" in hex (which is 25 3E 00 27) and those offsets are at 0x271421 and 0x2713F1 and those are in the range of GameFreak's Emerald offsets for messages so it should be there but I haven't been able to find any pointers to any offsets around that. Any help would be great. It's a great special to use for this feature but is incomplete and worthless if your team gets deleted.

That's strange, I've used that special and it doesn't affect my team at all.

One thing it does, is it changes the intro picture that's usually based on trainer class (team magma/aqua) to the last battle you fought. So, I had a battle with just a normal trainer but because my last battle was a team magma grunt, it displayed the magma logo.

Forgot to delete my post haha and I've been busy but I figured out my problem... I think it has something to do with inserting touched's tag team battle asm because after any trainer battle my party gets deleted soooo it's me :P thanks for testing it anyways!

So, if you change the Pokémon in the Wally scene (the one he uses), the attacks won't change. However, to change them, you could do this:

special 0x28 // stores party in ram
special 0x12F //overwrites first pokemon
setpkmnpp 0 0 64 //changes the first move, in my case, to peck
special 0xA0 //wally special
waitstate //required
special 0x29 //restore pokemon

I'm surprised that no one mentioned this one considering it's simple af, but oh welp.
special 0xE9: It checks the amount of happiness that the first Pokémon in your party has. It returns 0x0, 0x1, 0x2, 0x3, 0x4, 0x5 or 0x6.

I understood it by myself for the most part, but the actual relevant bit was provided by DizzyEgg and his IDB.

1f0 gives the hoenn dex and 1f3 upgrades it
BB gives an egg bred by the daycare

Hi there, I'm struggling to find something.

I want to find the level of a chosen pokemon in my party.

So I should do

special 0xA2
waitstate

to select a pokemon but then how can I retrieve its level ?

I want to use the level to give another pokemon with the same level (not to trade, to give)

Thanks a lot
