Using ScriptDec to view RSE/FRLG Scripts

[Dabomstew]

ScriptDec, as the title implies, is a program used to reverse compiled scripts into something a bit more viewable by humans. Unlike ScriptED or Pokescript, it actually does a decent job at doing this (no offense to the authors of those programs, but the decompilers are pretty unreliable, not that I'd ever want to be tasked with writing one). But being a DOS command line program, its use may confuse some people, so I compiled this small tutorial.

If you're a relative newbie to scripting, stop here. This tutorial isn't for you - it will not help you learn scripting. If you want to duplicate the effect of an existing script, you're better off just using that script as it is and changing the text.

Download ScriptDec: here

ScriptDec is made by loadingNOW, not me. As such, I cannot answer questions about it, or fix any bugs. I am simply providing a tutorial for its use, as when used properly, it is a valuable resource to hackers seeking to add new features to their scripts. To my knowledge, the last release of the program was in 2005, so the likelihood of an update is very small, though the source was included with the release.

There are two ways to use ScriptDec, one is actually notoriously easy which involves using EliteMap, and one slightly more difficult, but more reliable.

The Easy Way:

• Download ScriptDec from the above link, and extract it to a folder.
• Rename the main ScriptDec EXE file to scripted.exe
• Replace the scripted.exe in the folder of EliteMap with your renamed ScriptDec (remember to replace scripted with the original if you actually want to make a script using it!)
• Make sure your ROM doesn't have any spaces in the filename! (Preferably no special characters at all, but I know it doesn't work with spaces.)
• Open your ROM in EliteMap, find the event you want to see the script of, and Ctrl+click it.
• Press N and then Enter, as it is not a level script.
• The script will appear in your internet browser as a htm file.

The Other Way: (for if you dont like EliteMap, or it crashes when using your rom, etc)

• Download ScriptDec from the above link, and extract it to a folder.
• Copy the rom you want to view the script from into its directory.
• Find the offset of the script you want to view in AdvanceMap or EliteMap, and make note of it.
• Run the DOS command prompt, navigating to the directory with scriptdec in it, and run the command:
  

  scriptdec romname.gba:offsetinhex

  For example, for OAK's script in Fire Red:
  

  scriptdec firered.gba:169595

  For the offset, do not include any 0x or &H, just the six numbers/letters of the offset.
  If your rom name has spaces in it, make sure to put quotes around the rom name (but not anything else), like so:
  

  scriptdec "Fire Red.gba":169595

• Press N and then Enter, as it is not a level script.
• The script will appear in your internet browser as a htm file

ScriptDec can decode level scripts, but is not very good at doing so as it does not recognize the 02 structure that is used for the bulk of the script. If you want to actually view a level script, interpret the structure according to Baro's tutorial in order to find the offset of the main bulk of the script, and view it as a non-level script.

Sometimes, the script may appear blank or incomplete in your browser. Don't worry, this isn't a sign of failure, it just means ScriptDec opened the web browser before it finished decompiling the script. So just wait a couple of seconds, then refresh the page. The script should appear in its entirety, or at least up until the point which ScriptDec can decode (it seems to stumble on the hex command C7, but I haven't found any other problems yet).

ScriptDec is not a miracle program. It will not solve the problem of making custom trading scripts, or doing anything you want in a script. It is, however, very useful for finding new commands and specials to use in one's scripting.

If you understand scripting to a good extent, I recommend looking through the source-code of ScriptDec (provided in the zip) as it has several commands not found in the ScriptED or PokeScript command databases that can be useful to your scripts.

Where he is link for Download?

This doesn't work for me. I renamed it to 'firered.gba' but it tells me: Error opening file Firered,
Usage: ScriptDec Romname.gba: [offset in hex]

 

[Elementologist]

I'll provide the link for everyone: ScriptDec

This doesn't work for me. I renamed it to 'firered.gba' but it tells me: Error opening file Firered,
Usage: ScriptDec Romname.gba: [offset in hex]

I'm sure you did something wrong. I tried it at least five times to get it right. This is what you have to do: Say your rom is pokemonfirered.gba and your offset is 16582F. So you write (Once you are in the ScriptDEC dir in DOS):
scriptdec pokemonfirered.gba:16582F.
To go to the directory in DOS, you type cd and then your directory.
For Instance: cd Users\Person\Desktop\Scriptdec

I Have A Question. Okay, scriptdec decompiles scripts, but does it also compile, I mean, can I use it to add scripts to my rom?

 

[D-Trogh]

Well.. I know ScriptDec for a while.. and I made a batch file so I can work faster XD

cls
@echo off
echo Pokemon FireRed
set choice=
set /p choice=Offset: 
ScriptDec FireRed.gba:%choice%

Paste this in NotePad, save with 'All files' selected as: FireRed.bat
Now, when you have ScriptDec, this batch file and a FireRed ROM (Named: FireRed.gba) in the same folder and you execute the batch file.. You are asked to write the offset. Ones that's done, push enter and choose the script type (Level script or not).
Maybe I can edit ScriptDec source to be more user friendly.. :-\

I Have A Question. Okay, scriptdec decompiles scripts, but does it also compile, I mean, can I use it to add scripts to my rom?

No, it doesn't. You can only view scripts and nothing else.

 

[Knox]

D-Trough yours does not work.

When I type in the offset the black box just disappears?

 

[cooley]

@knox: I know what you mean....

 

[Knox]

Hey cooley make sure your ROM isn't patched.

That might be the reason it doesn't work.

I haven't tried it yet so it may not work

 

[thethethethe]

That shouldn't be the problem. It should work even if te rom is patched.

 

[Knox]

Yeah but what if some of the offsets got deleted?

Like I was trying to use an oak script in a Shinygold ROM?

Wouldn't that not make it work?

 

[thethethethe]

Yeah but that's different. That's kind of like looking for a fire red offset in a ruby rom. There is no point. The only reason you'd look at a patched rom would be to view an uncommon script like the Red Gyarados or any other new scripts. If you wanted to view the oak script, wouldn't you just look in a normal FR rom?

 

[Knox]

Yeah I know.

I forgot it was a SG ROM.

 

[cooley]

Although some people don't need to, a reason ScriptED may not work for many is because it doesn't see the file extension. To make it see it, in a folder, go to Tools> Folder Options> View, and turn off the "hide filetype extensions" box. That is how you make it work.


Works for me now.But, How do you know if it is a level script or not?

 

[Knox]

Hey thanks cooley but I have no idea what a level script is.

But if your script is screwed up I guess that is when you can tell

 

[thethethethe]

Well it depends what you clicked through in Elitemap. If you clicked on a person event or a trigger event, it's a normal script. If you clicked the button at the top that says view level script then, obviously, its a level script.

 

[johnlycett]

Well, strange i did it but comes up with couldn't find scripted.exe When i renamed it so weird. lol

 

[Satoshi Sugimori]

uhm I have a question I do exactly as in the tutorial (The other way) and it works good but when i do n and then push enter it just goes away and nothing happend...
help please...

and maybe an idea
maybe you should use screenshots by every step it is easier to understand...:)

 

[opeious]

Well i didn't use the first way because elitemap doesn't work on my PC bt it used to earliar mut anyway the second way works eg:-

[ASuch]

I can't get this to work.... It automatically gives me this: C:\Users\Blank>, so this was what I put in:

C:\Users\Blank>cd Downloads> ScriptDec scriptdec firered.gba:800E9BN

I click enter, and then it says that the path could not be found. Can someone help?
