Hey guys, I've finally made an ACTUAL* BW2 repel system for emerald.
Okay, before I start off, you're gonna have to credit Darthatron, and Phenom2122, and if you want, Le Pug, Tcoppy, and I.

Anyways, follow the tutorial here, http://www.pokecommunity.com/showthread.php?t=281573 and do the Emerald part in another post instead.

Once you have that done, you're going to have to make this script for all of them:

For Repel:
Code: 
#dynamic 0xE40000
#org @start
compare 0x40e9 0x1
if 0x4 goto @no
removeitem 0x56 0x1
setvar 0x4021 0x64
setvar 0x40E9 0x1
sound 0x2F
msgbox 0x8E4D3B9 MSG_SIGN '"[player] used a Repel."
end

#org @no
msgbox @nope MSG_SIGN
end

For Super Repel:
Code: 
#dynamic 0xE40000
#org @start
compare 0x40e9 0x1
if 0x4 goto @no
removeitem 0x53 0x1
setvar 0x4021 0xC8
setvar 0x40E9 0x2
sound 0x2F
msgbox 0x8E4D278 MSG_SIGN '"[player] used a Super Repel."
end

#org @no
msgbox @nope MSG_SIGN
end

#org @nope
= But the effects of a Repel\nlingered from earlier.

For Max Repel:
Code: 
#dynamic 0xE40000
#org @start
compare 0x40e9 0x1
if 0x4 goto @no
removeitem 0x54 0x1
setvar 0x4021 0xFA
setvar 0x40E9 0x3
sound 0x2F
msgbox 0x8E4D2F5 MSG_SIGN '"[player] used a Max Repel."
end

#org @no
msgbox @nope MSG_SIGN
end

#org @nope
= But the effects of a Repel\nlingered from earlier.


Change the offsets for the dialogue or it won't work.
You can also change the second variable, to whichever you want/is safe, but you'll need to change it later.

Then, make a script with this:

Code: 
#dynamic 0xE40000
#org @start
msgbox @wore MSG_SIGN
compare 0x40E9 1
if 0x1 goto @repel
compare 0x40E9 2
if 0x1 goto @super
compare 0x40E9 3
if 0x1 goto @max
end

#org @repel
checkitem 0x56 1
compare 0x800d 1
if 0x4 goto @yesrepel
setvar 0x40e9 0
closeonkeypress
end

#org @yesrepel
msgbox @use 0x5
compare LASTRESULT 1
if 0x1 goto @userepel
setvar 0x40e9 0
closeonkeypress
end

#org @userepel
removeitem 0x56 0x1
setvar 0x4021 0x64
setvar 0x40E9 0x1
sound 0x2F
msgbox 0x8E4D3B9 MSG_SIGN '"[player] used a Repel."
end


#org @super
checkitem 0x53 1
compare 0x800d 1
if 0x4 goto @yessuper
setvar 0x40e9 0
closeonkeypress
end

#org @yessuper
msgbox @use 0x5
compare LASTRESULT 1
if 0x1 goto @usesuper
setvar 0x40e9 0
closeonkeypress
end

#org @usesuper
removeitem 0x53 0x1
setvar 0x4021 0xC8
setvar 0x40E9 0x2
sound 0x2F
msgbox 0x8E4D278 MSG_SIGN '"[player] used a Super Repel."
end

#org @max
checkitem 0x54 1
compare 0x800d 1
if 0x4 goto @yesmax
setvar 0x40e9 0
closeonkeypress
end

#org @yesmax
msgbox @use 0x5
compare LASTRESULT 1
if 0x1 goto @usemax
setvar 0x40e9 0
closeonkeypress
end

#org @usemax
removeitem 0x54 0x1
setvar 0x4021 0xFA
setvar 0x40E9 0x3
sound 0x2F
msgbox 0x8E4D2F5 MSG_SIGN '"[player] used a Max Repel."
end

#org @wore
= The Repel's effect wore off[.]

#org @use
= Use another?

After you're done with that, go to 0x2A4B2A and replace the script there with "goto and 0x(the offset for that script).

It hasn't been tested much, but it should work. If you find any bugs, write them here.

*The only difference is that the screen goes to the Overworld when using it. Sorry about that, but I really don't know any other way to do it.

Ah, a way much more efficient than mine! Nice find, Sneasel! Never would have dreamed of using that way! I'm gonna test this out soon!

Nice find ! But I tested and that doesn't work, are you sure about the 0x2A4B2A ? And what are you calling "goto" ? Just make a pointer of our script ?
Oh yeah, precisions could be useful.
The first repel works, and after nothing happen, not even the "repel wores off". But if I try to use another it says "already used". Then I saw a pointer 2 bytes after the location you given. At 2A4B2C, so I tried to replace that pointer with the one you gave :
The first repel works. Then I walk until it wores off, and then a textbox with weird things appear, and I can't reuse a repel, when I try it said "already used".
I've correctly repointed the textbox so, I don't know why it does not work

I did the goto cuz I was too lazy to go back and actually point it to the script (repel's effect wore off), lol. Did you make sure to follow both tutorials properly? Had you used the var I used before?

Yes I did. Basically I copied/passed your script, changed the textbox, added a textbox for the repel because it was missing. But I don't know what are you calling "goto". I know if the address of my script is 95 00 00, a pointer is 00 00 95 08, is that are you calling goto ?

And for the Darthatron (adapted by phenom) callingscript from item, I already used this and worked every time so I'm sure I haven't missed something here.

Hmmm... anyone have this completely ruin the effect of repel? It just lets me use it infinitely but it no longer repels and I never get an end message.

Edit: I swear I mess everything up the first time on everything I add... I got it working! Works great.

Can someone actually make a video tutorial on this, so I can see how to do it? I'm not one of those learners by just reading things, but I'd prefer to just have a video ready so that I can easily just repeat the process in my head. It's really appreciated if you do that. Thanks for your help.

Well, I don't mean to sound like a dick, and I could be wrong, but I don't think anyone really will. Most tutorials for ROM hacking are written, not videos.. Why not give it a try like this and just ask questions if you get any?

You know, you're actually right about that. I guess I need to find that extra learning style that I've yet to discover. But, I'll try my best, & see how it goes.

Alright, I managed to get to the point where I'm alerted that my steps are up and I receive my question. When I answer no, my game is fine. When I answer yes to use another repel, my game freezes. I've gone through all of the bytes twice, but haven't had anything change.

I'm trying to implement it on an already started hack. Though, I haven't made a ton of progress. I'm able to restart I think, to get this and whatever else I want in my game now.

I take it this isn't compatible with MrDollSteak's FireRed rombase? I followed the instructions in the OP to the letter and the game freezes when the repel's effect wears off.

A friend got that system for RUBY without insert any ASM rutine, can I ask why I need it in Emerald?
