[Other] How to replace the Regis in Emerald?

[LegendChu]

Okay as everyone knows the Regis - Regirock/Regice/Registeel, are found in Desert Ruins/Island Cave/Ancient Tomb respectively in Emerald.

Now I want a different Legendary to be found in those locations, like say Dialga/Palkia/Giratina, where is the Script I need to alter, for that?

Just go into the caves in Amap, you'll see the regis ow, then open it's script. There'll be a setwildbattle just change the parameters there.

I would rather prefer to make the changes using a Hex Editor, coz that's seems safer.

Can someone please tell me the Offsets where I can make the changes, for each Regi?

You're just replacing one byte with another. It's equally safe.

Okay, this is the Script for Registeel in Ancient Tomb

= The [buffer1] flew away!

So basically what you're saying is I just change the line:-

startwildbattle 0x193 0x28 0x0 (the one I've underline in bold, in blue) (btw, the does the Level also have to be in Hex Value, coz I just noticed that?)

to something of my choice, say

startwildbattle 0x091 0x32 0x0

So will I then be battling a Zapdos at Lv.50 instead?

Or do I have to change all instances of 193 to 091?

Yeah, you just change the 0x193 to 0x91 and you'll be battling a zapdos. Additionally, before the wild battle command the script says "cry 0x193 0x2" so you gotta also change that to "cry 0x91 0x2" or else the ow will still make a registeel sound before you fight it.

 

[C me]

Also the setvar at 0x2390AA, that's used to set the name for [buffer] flew away.

So basically I just need to change those three values (the ones in blue), just hit save & I'm done, right!

P.S. - I'd appreciate if someone can answer to a similar question I asked here https://www.pokecommunity.com/showthread.php?t=355379, regarding changing Kyogre/Groudon/Rayquaza, coz I think they'd work a bit differently.
