GSC Item Editor
An Item Editor for Pokémon Gold, Silver AND Crystal

Version 1.2
Download As: Zip

My latest tool. This allows you to edit everything about items in Gold, Silver, and Crystal Versions. Has no known bugs, but if you find one let me know. It detects which version you loaded and will load the data appropriately, and if it doesn't recognize the rom, it won't let you edit it. It also refuses to let you edit Item 0, and some of the later items will have the ASM Pointer greyed out. This is because the later items do not have valid ASM pointers, as they work differently, and this is to prevent you from accidentally your rom.

Hey are you still working on this?
I wrote an array that works with loading names in GSC.
If you have MSN or something let me know and I'll send it to you if you want so you can add the item renaming.

Mateo · 1970-01-01 00:33:30

Hey thanks mate. Yeah, I have MSN. zoot_suit_riot07@hotmail.com

Gamer2020 · 1970-01-01 00:33:30

Ok I added you.
But I noticed a little bug in the array.
It's not to bad its just that for renaming I would need to fix it.
Basically since "Poke" is represented by one byte and the array handles only one character it comes out only as "P".

Mateo · 1970-01-01 00:33:30

Ah I gotcha. Yeah need to take care of that haha.

Gamer2020 · 1970-01-01 00:33:30

It's fixed.

Also I noticed that you got the old style GUI stuff.
For example the buttons aren't round. I got the Module and resource to fix that. ;)

Just gotta see you on MSN LOL

Mateo · 1970-01-01 00:33:30

Ah alright. I mean I'm running Visual Studio 6.0 enterprise edition. And while those would be taken in vista, I'm now running XP so i'm not as bothered by that bit, but I can include that if people want it :P and I'll get on, sorry I forget to sign in sometimes.

Gamer2020 · 1970-01-01 00:33:30

I am using the same VB6.
You'll see what I mean with the program thing.

Mateo · 1970-01-01 00:33:30

okay

Gamer2020 · 1970-01-01 00:33:30

I might have to send you the stuff through PM since you haven't gotten on :P

Mateo · 1970-01-01 00:33:30

I'll get on later today. One thing is I seem to have misplaced part of the source for my item editor, and I don't know how I managed that, since all files should have been in the same folder. Anyways, that would make it take a bit longer to release a new version, but i can still work on it, and I'll still get on and check out that code you're talking about

Miksy91 · 1970-01-01 00:33:30

I just learned how this tool works :D

My idea was to make Slowpoke evolve with King's Rock to Slowking but it didn't work the way I wanted it to; I got always this message (Oak: "HIRO, this isn't the time to use that.") until I learned what ASM pointers are for (or I at least know much better now).

Also, the evolution does happen with King's Rock now & you can get only one King's Rock in the game and that's why you can't toss it away either) ;)

Mateo · 1970-01-01 00:33:30

Good deal! Sorry I didn't explain that better earlier that it took this long to figure out, but glad you got it working right for you

Miksy91 · 1970-01-01 00:33:30

Good deal! Sorry I didn't explain that better earlier that it took this long to figure out, but glad you got it working right for you

"this long" was around 20 minutes :D
I found the tutorial for doing this a while ago and I checked what the item data is like in hex then.

Masterge77 · 1970-01-01 00:33:30

Maybe we can use this to find out what those "Teru Sama" items do.......

Mateo · 1970-01-01 00:33:30

Oh okay :P I had assumed it had been since around the time it was released. Lol

Miksy91 · 1970-01-01 00:33:30

Maybe we can use this to find out what those "Teru Sama" items do.......

I believe those are unused data in the item/tm/hm set.
So, if there were 245 items overall, there would be 11 teru-samas.
At least, that's what I think...

Mateo · 1970-01-01 00:33:30

That's right, they are just unused filler data. Most don't do anything, but a couple of them I know do. One is a pokeflute, and the other is a town map that doesn't work right (However the town map item in SaR is not actually using this code, i made it point to a new script that just calls the normal town map you see in houses)

In response to Cloud96's question in this thread since it got locked while I was typing my reply :( : http://hax.iimarck.us/topic/200/

ABOUT EDITING EVOLUTION ITEMS

You also need to edit the evolution data of whatever you want to evolve. This can be done without difficulty using an old DOS tool called HFD by MeowthHacks - I do not know if there is a newer tool that can do the same thing, other than through hex editing. Change it to "Give item evolution" instead of "trade with item evolution". I think Mateo might have a download link, he was the one who sent it to me originally.

I do not know the hex editing offset, maybe someone else does.

BEWARE: Changing Metal Coat to be an evolution item will make it lose the Steel-type power-up hold effect.
What I did was make a new item out of one of the Teru-Samas called Iron Ore, and made Scyther and Onix evolve from that. I made it available at the Goldenrod Pokemart with all the stones. That way, you can still have the evolution item AND the power-up item.
Make sure you change the item options so you can use it.

I also did the same thing for Slowking, made a new item called Crown and did the same stuff. I also made Politoed Water/Grass and made him evolve with a Leaf Stone.

Unless you know how to edit them, none of the new items will have descriptions.

Also, this is easy to do for the Up-Grade to make Porygon evolve into Porygon2, just change the ASM and the Evolution data since the Up-Grade item is useless otherwise.

Mateo · 2011-01-03 04:42:52

Also in answer to his question, it seems that "able/not able" is defined by something other than just evolution data. In the Christmas Hack, I made the Ice Shard to evolve Eevee into Glaceon and it says NOT ABLE, but if you use it anyway it still works.

EvilOttoJr · 2011-01-03 05:38:11

Hmm, that's odd, since it made everything turn to "able" that I needed it to in my hack... I wonder why that is...

Mateo · 2011-01-03 07:30:57

Hmm, Idk. Maybe I'm remembering wrong, been a bit since I added Glaceon to remember for sure. Either way, so long as it works.

Umm.... Can you give me a link or send me that tool via email? Thanks and sorry to bother you....
Also thanks to mateo and sorry to IImarckus for my mistake :-)

Yeah, PM me your email address and I'll send it to you as an attachment.

Cloud · 2011-01-03 10:42:07

I can't PM you. So, I send you an email. Check it.

EDIT: I got it, thanks.
