The (Un)official Pokemon GB/C Hacking Support Thread

[masterz2010]

hey people this is the creator of pokemon prehistory sayin that pretty soon i will release the beta of the first 2 gyms so check it out (ps butcha i support the thread)

Thanks for the support everyone. I have a Topic (Team Alpha) in the Team forum for anyone who wants to get involved with a Gold hack. We also accept new ideas and, as members come in, may divide into groups and work on multiple hacks at once. I dont hate FR/R hacking (I have a FR hack planned), but GBC is my favorite by far.

yea and ill have my first hack out soon ill send it to you first (prehistory)

 

[Dabutcha]

Thats kinda off topic ryan :\. This is about GBC hacking, not FR...even though you support it.

 

[masterz2010]

i was commenting on the fact that within the post you said you had a FR hack so i said i will be coming out with one

good point coolboyman using programs may be useful but hexing has a wider spectrum of possibilities

I've always wanted to post this, so here goes:

Believe it or not, my first Pokemon game was the Japanese Red/Green. Anyways, after we moved to America, I was pretty pissed that my US Gold version could not link up with my Japanese Red/Green versions without getting all glitchy. So I got the US Pokemon Blue. The first thing I noticed was how weird the graphics are. This was because in Japan, the "third version" of Gen I is NOT Pokemon Yellow, it was actually Pokemon Blue, which was basically Red & Green with enhancements, just like Crystal, Emerald, and Platinum. When they decided to localize the Pokemon games, rather then translating the Red & Green roms, they decided to translate the Japanese Pokemon Blue, due to it being less glitchy than Red/Green, which is why the graphics are different from Red/Green to Red/Blue.

Here's a comparison. Left is Japanese Red/Green, right is US Red/Blue & Japanese Blue.

So I've always wanted to play through Red/Blue with the original graphics, and I've finally figured out how to hack it. Below is an ips patch for Pokemon Red that changes the graphics back to the way it was in Japan's Red/Green.

EDIT: The flower animation has not been changed yet, and all the Pokemon sprites have not been changed yet either.

EDIT: Oh, and I support this thread!

Hmm.. poit! <3 Second gen's pretty special to me. I'm old enough to have been there when first gen took off, but still there's something about second gen. The art style and music style, I guess you could call it the flavour. So I'm much, much more inclined toward second gen hacks. I know nothing about hacking, but from what I understand it takes some dedication, which is definitely a good thing, if nothing else it filters out those who aren't interested or mature enough to piece together something really special.

What I'd love to see at some point is an attempt at second gen with Fakemon (forgive me if it's already been done, I don't really check up on here too often!). I used to mess about with sprites years ago and I used to love GBC-style aesthetics.

Kudos to all you out there giving second gen hacks the quality they deserve :D

 

[Dabutcha]

This sure is back there. I really wanna thank you all for supporting this thread.

What's up, long-time Pokemon player here, and I have some experience hacking 3rd gen Pkmn games. But I happen to be new to Pokecommunity itself.

Just wanted to say, I strongly support this.
Gold was my first Pokemon game, and I've always wanted to make a hack of it.
Unfortunately my hex-editing skills are rather limited :/

There is nothing hard about hex-editing.
Doing changes that are in brown/prism are difficult to be done but other editing is usually easy. If you made a hack, you would learn how to edit trainers, wild pokemon, maps and text quickly (without editors if you wanted to) but scripting isn't as difficult as people say either.

Join the Skeetendo (the picture with link is in my description below).
You can find a lot of tutorials on how to change different things.

im currently learnin hex editin. its easy until you get up to double digits e4 ect im lookin at skeetendo for a scriptin guide for it. can anyone help me?/bit off topic ya i kno. sign me up for supportin

EDIT: found the tbl file for silver/gold/crystal/red/blue/yellow. time to get crackin'

 

[dragslayar]

i'd like to learn how to hack pokemon silver (and i mean proper hex hacking) but i need help getting there

and a tool i think would be good is one to change moves types accuracy and power

edit: ive just stumbled accross a amazing editor, it can edit almost everything (including moves accuraccy and pp (i havnt tested it fully yet))
but i cant post the url cause i havnt done more than 15 posts, and idk how to upload files.
buti'll see what changes the editor makes to the hex and do some hard work for it (it'd be no fun if it was easy)

[dragslayar]

Also i found a map editor for red and blue.

So, if you google "mattios blue map" you'll find a page at the top witch holds alot of tools for modding both gold/silver and red/blue.

 

[hi sir tomato my password is syvniti]

What gameboy color debugger would you suggest?

 

[Jenga]

I support this topic.
I'm starting hacking now and I want to learn it the right way.

I already know something about Hex.
------------

By the way, I have a question about editing the starters in Gen I games.
CoolBoyMan's Rom Map says it is from 3A1E3-3A1EB. Well, I found the pokemon hex there, changed to the ones I wanted, but then only the rival's pokemon change, mine remains the same.

They are different kinds of data.

The rival's starter is stored as part of his team data, with the rest of the trainers. This is what you edited.

Your starter is defined by a script in Oak's lab, which defines what Pokémon are stored in the Poké Balls on the table. This can be edited with assembly.

A lot of those links are broken. I'll update them eventually.

These twillight forum links doesn't work.

Oh... ok.
Assembly is the only way? That's really difficult, isn't it?

 

[tatanga]

hmm, is there any way to edit the pokemon battle pictures for Pokemon Red currently? If not, is there a way to edit the ones from any of the other colour (or even metal) generation games? Then at least I could find the code using a hex editor and reinsert it in the appropriate slot for my Red hack.

Twilight Hacking was taken down in a fit of power by its administrator. I'll replace those links sometime.

Not if you know assembly.

Gen I and Gen II use two different compression schemes for Pokémon images and are not directly compatible.

Currently, no program exists to compress images for Pokémon Red (that I know of). With assembly, however, you can redirect the image decompression routine to not require compressed images at all—this was done in Pokémon Brown.

Two programs exist to compress images for Pokémon Gold: Agixp and "Meowth's GFX Inserter." You can compress and insert images using these programs, or like Red, can reprogram the decompression routine to not require compressed images (although you would probably run out of space in your ROM very quickly).
