Research: [GENERAL THREAD] Pokémon Heart Gold/Soul Silver Hacking

Oh, no wonder. I don't have a clue what to do with textures.

I wanted to grab them myself because I'd only seen them on TSR slapped haphazardly into a big montage. If you don't mind my making use of these, do you have a tarball or similar?
 
Not a huge surprise there, all of rotoms forms have their own overworlds. Nice find though.
 
Yay! SCV has arrived! if the model structure is the same I should be able to spit out a hack video in a week or less! the plattet and sprites also seem to be the same, so that shouldn't be a problem. And sorry about my stupid question. Also the ROM crashes at random places, even on r4ds (i have one!) such as After wild battle, While walking in grass. Remake, my foot, this is a total remodel of the interface! even the bag is 3D! I can't wait for the English version!

I've looked through the map files and they retain the same structure (minus some little change in the file head size and the note below). In fact my map viewer is finally almost done! (dppt/hgss)

There is something different with permissions, where 06 is the default free movement byte instead of 00 (in New Bark at least).
 
Hmmm...

I know where are the trainer data if you haven't find them

They are like around

2FDAxxx or something

Bai.
 
Encounters are in /a/0/3/7 and /a/1/3/6. One's HG, one's SS. Contains:

Eight bytes for encounter rate (grass, surfing, rock smash, old rod, good rod, super rod, padding, padding)
Twelve bytes for levels
Twelve words (16-bit) for morning grass Pokémon
Twelve words for day grass Pokémon
Twelve words for night grass Pokémon
Four words for some sort of special encounter; always two from Hoenn and two Sinnoh, and only populated when there are grass Pokémon. Seems like a PokéRadar type of thing, but it also works in caves?
Five dwords for surfing
Two dwords for what appears to be Rock Smash
Five dwords for Old Rod
Five dwords for Good Rod
Five dwords for Super Rod
Four more Pokémon words that seem to correspond to grass, surfing, good rod, super rod. Most of the time these are the four most-common Pokémon available by grass/surf/rods, but there are a few uniques like Clamperl and Poochyena.

Water dwords are { uint8 min_level; uint8 max_level; uin16 pokemon_id; }.

Here's a more readable dump of, um, one of them. I forget which it was. http://pastebin.com/m1f33764d

Need to know what the two specials are, whether that really is Rock Smash, and what areas these correspond to for this to be useful.
 
which is the best anti-piracy patch? because mine doesn't seem to work very well :(
 
Okay, Done! I successfully hacked the game in 5 minutes. That Was Easy!(C) Anyway, the maps seem to be in order! Yay! this makes map hacking a lot easier! heres a link:

Several are being worked on but only 1 is being made.

I think there's a frame3, though, which I don't have.
 
I've been (slowly) trying to go through and document every NARC file I can. I'm missing a few things in this thread yet but I'll be continuously updating the file at this address: http: //dl.getdropbox .com/u/258536/hgss-filesys.txt Enjoy.

Most if not all of the DPPt tools still apply... That's the glory of NARC files. The only troubleyou will have is finiding the right one, which is why we are mapping out the contents of each NARC.

You might wanna look into some map "hacking" that is actually productive... Full documentation of the model file format can be found on these very forums, and Alpha aka pokesplash has a promising viewer in the works.
 
Thanks alot Eevee ^_^ Now i can start on my hack

EDIT: T_T need frame 3

Congratulations bro, you managed to improperly edit a well documented format with no difference from any of it's previous uses.

Third (or maybe zeroth) frame is a lot easier; they're all just regular tiled sprites using the same palette in the same file. I would imagine anything that can pull sprites from DS games can get them for you.

I think I have about everything I could possibly need for veekun by now, but this is excellent and I applaud your efforts.

Oho. It would be really nice to have flattened maps of all the areas sometime, for a beautiful visual walkthrough of Johto/Sinnoh. I've seen a few for D/P on Bulbapedia, but I suspect they come from lots of screenshots or are manually put together.
