there was no need for attitude I know about hex editing that is how I have been doing it I was just thinking it would be easier with a pre made tool...

But anyway yes it is exactly the same DPPt so yeah it is pretty simple enough I guess

Could someone who knows how it wirks please explain trainer battles in HGSS (I'm talking Hex)

also incase people wanted to know the offset for movesets starts at (In a clean HG ROM) 29EF818

All I know is that it's in ARM, not the usual filesystem. You might have some trouble finding it though because all the overlays are compressed (they weren't in DPPt, but HGSS packs a lot more into the same space).

I have a few questions:

1. Can .narc files be edited with a hex editor?
2. Is it possible to edit opponent teams with a hex editor?
3. Is it possible to edit the Pokedex order with a hex editor?

Yes, all possible. Isn't it just nifty what you can do with a hex editor?

You must not understand the concept of a hex editor (for the record it could just as easily be a binary, octal, decimal, etc editor, hexadecimal is just a convenient number systems when it codes to computers).

Everything on a computer is represented, on its lowest level, by numbers stored in memory. A file is just one big, long number. Therefore any file can be opened and of course edited in its numeric form. Your success in editing it to achieve a desired effect will depend on how well you understand that file, but it will always be possible.

Since humans aren't machines we find it much easier to understand things other than numbers, so we make programs (which themselves are a number) that will turn that big number of a file into something meaningful, usually graphically.

Wow, that is awesome.

Once the official English HG/SS Rom is dumped in March, and if nobody makes a tool to edit trainer teams and the Johto Pokedex order, I'm going to do it myself with a hex editor.

...But I would have to make a table file first...

Well that would be very unethical to actually create a program with a hex editor? First of all it is mainly for simple byte edits or finding something to use. You would not use it actually to create a full program. You see once you actually find the offset to what you need you can make a program programmed in something else read this if you can get it to load the file etc.

I think you mean 'inefficient' or 'ineffective', not 'unethical' :P
I think AztecFire meant he's going to edit the Pokédex order directly with a hex editor, rather than wait for tools.

Yeah, that's what I meant. And it doesn't matter how I do it, as long as the final outcome is how I want it to be.

Has anyone found out how the trainer data bytes are stored? I remember someone saying that it's different from D/P/Pt, which is why a D/P/Pt trainer editor won't work.

sprites?

I was wondering is it possible to replace sprites yet on hg/ss i know that some people have been able to replace lugia sprites, and dialga sprites.
I was wondering because I recently made a ash's squirtle sprite sheet, but I have no knowledge of hg/ss hacking to upload this.

does any one know which flash cart runs HG/SS the best?
I think almost every flashcard runs HS/SS. Some require patching or the use of cheats, others (the ones getting updated - M3iZero f.e.) don't require any prepatching or the use of cheats. The anti-piracy gets patched when the game loads/runs.

You can change the Pokémon sprites with PokéDSPic (Platinum) if the first post is correct:
First Post (D-Trogh) said:
Actual Pokémon Sprites (The NEW ones) are stored in a/0/0/4; 4 being a NARC archive and it uses the Platinum encryption.
For the OWs you can use PokéTEX (in combination with TileMolester for quicker editing).
