If I'm understanding this post correctly, we can't edit anything past 0x09FFFFFF.

In a Pokemon Gold hack what should I do first

Can anyone think of why in my FR/LG hack, events such as Oak stopping you from leaving Pallet w/o a Pokemon or Gary challenging you would make wrong noises? Like the Oak thing, his song wouldnt play (Pallet Town music continued until entering Oak's lab) and, and when Gary challenged me, the poisoned sound effect played.

Well, you can start anywhere. A lot of people like to start with the map. Some like to dive into editing Pokemon sprites or Trainer data first. It all depends on where you want to start.

Hacking information

Hi!

I'm going to make a pokemon hack of ruby. I have knowledge of ASM and pointers, but there is an important point I never knew... it's how to find a data... for example, if I know where is a pokemon graphics, is there a way to find where is the pointer which points there? can someone tell me how I can find it, or know a tutorial where I can how to do it?

any hints would be appreciated!

thx

I have an ASM related question... I just finished this simple asm tutorial: http://www.pokecommunity.com/showthread.php?t=233645

And I have a question after finishing it.... How woulgd I store data from a register back into the RAM. For example, what I'm trying to do is the following:

I want to level up my Pokemon by 2 levels. I do this by taking the pokemon data at the level bit area, and then add that up by 2, and then I want to store that data again... But command prompt won't assemble my asm and gives me an error, stating that I can't store the pokemon data.

Here's the ASM code I'm using:

Neither work when I try to assemble them.

I guess there is a different method to storing things back to the RAM? Or am I just being stupid? :P

I'd love some help!

I don't know if increasing the Level byte without changing the experience is such a good idea but regardless, try this:

Wow thanks, that worked! :D

No it isn't supposed to be functional or useful, I was just trying some things out and trying to learn ASM in the process :P

So, I'm trying to understand what you did there.

First you load the word at pokemon_data in r0.
Then you do the same for r1, using the address used to load r0.
You add 2 to r1.
You store r1 back to the address of r0.
Then you end it.

Am I getting it right like that?

And if so, could you also do it by only using one register? Like so :

Thanks for helping me. I'm really interested in learning this! :D

You can't use one register because if you load the level byte into r0, then it will overwrite the address that r0 previously contained. You'll have to use a minimum of two registers: one for the address, and one for the level.

Waaait, so:
loads the address of pokemon_data into r0 and not the actual level bit?

Code:

ldr r0, pokemon_data

"ldr r0, pokemon_data" loads some address, in this case 0x020242d8, into r0. "ldrb r1, [r0]" loads the byte that is stored at whatever address is in r0 and puts it in r1. Finally, "strb r1, [r0]" takes the contents of r1 and puts it at whatever address is stored in r0 (which is still the address of the level byte). So, that routine loads a byte from the RAM, modifies it a little, and then puts it back where it got it from, overwriting what used to be there.

Alright, that's what I did not get from the tutorial. I didn't really understand the difference between ldr str and ldrb and strb. But now I do, thanks so much :D

Does anyone know how to change the Pokemon's small sprite? The ones that look like this?

Wichu has made a tool for editing Pokemon Icons ;)

Here's a link

I've inserted a bitmap sprite in the place of Torchic on Ruby, and it works fine when you battle against it but when you use it in battle (i.e. see its backsprite) or see it in the pokedex, the game freezes or restarts just before you would see the sprite. I used nameless sprite editor to insert the image. Does anyone know what the problem could be?

Hey, I have a few questions. How do I edit the main trainers sprite. I've indexed the file, and then I replace it in UnLz, but it looks messed up so I tried to change the palette in APE, but It said not to, the reason is because when I clicked ignore the game now freezes and goes black when I click the trainer card?? I was thinking that I should insert the sprite into a empty slot and then repoint the offset so the game uses that trainer, but i'm a complete newb, so how would you do that?


Also, I've looked over mapping and it's seem very annoying as when I say change one part of grass, loads of it changes all through the world, when I only want that spot. Is there any way to only change the one spot...?

In Pokémon Gold can you use the RAM Map in PKSV-UI

Pokemon Emerald 1.0
Advance Map
XSE

Does anyone know Bagon and Trapinch's hexadecimal number?

Oh, and could I make a title screen in Adobe/Macromedia Fireworks and somehow send it into unLz.gba to use as my titlescreen? I need the titlescreen number too for unLZ.gba unless there's another way I could edit the titlescreen.

Check this link; these are decimal but you can use windows calculator to convert them in hexadecimal format.

And if you don't know how to do that, XSE comes with a file called "stdpoke.rbh" which contains the hexadecimal numbers for every pokémon from the first three generations.
