[Ongoing] Pokemon Emerald Specials

[Dark Sneasel]

As the thread title says, this thread is about the Emerald specials. The Emerald specials are much less documented than the ones in Fire Red so the purpose of this thread is to get more information on them.

The special table in Emerald is 0x20E entries long, with each function being located in the table at 081DBA64.
If these offsets could be futher confirmed as to what they do, either by means of looking at every used special thus far or further research, that would be nice.

Here is a few lists of specials:

0x8 - takes you to a secret base with a guy in it. Can warp back to original position.
0x9 - warps you to warp 0 on map 0.0
0xA - same as 0x9
0xD - deletes everything on your computer. Nah, jk. Idk what it does
0xE - brings up menu "Decorate, Put Away, Toss, Cancel"
0xF - message "There is no registry" then brings up menu "Decorate, Pack Up, Cancel"
0x18 - teleports you to X1, Y3 of the current map
0x1A - PC shut off sound and tile is set to something else
0x1B - "Please Wait ... ... B Button: Cancel Mixing Records..." followed by twinkling sound and the Mixing Records textbox doesn't go away. Kind of cool though cus you walk around with the message box up and if you go to a new location, it moves up and down with the sign in the top left corner telling you where you are.
0x1D - locks player in place (aka lock command)
0x1E - unlocks player in place (aka release command)
0x21 - "Please Wait ... ... B Button: Cancel" then battle with a level 4 Poochyena ... maybe saving the professor? Anyways, it'll save your progress then give you a communication error. epic troll special.
0x22 - "Please Wait ... ... B Button: Cancel" then message pops up after fade out saying "Communication standby ... please wait" then communication error
0x24 - brings up player info and Would you like to save? message. without a lock in your script, you can walk around with the message up.
0x27 - voodoo ritual where clones of you appear in a circle staring at each other.. usually one of them has a palette error
0x29 - deletes all pokemon in party unless its storing it to be retrieved by some variable or special
0x30 - turns all hidden sprites into soil sprite (sprite #60)
0x3A - same as #raw 0x56 aka it pops up a ! emote box above the player's head
