How to add a new Pokemon. (Complete Tutorial)

I have been learning so much from this site, thanks so much guys!

I have a quick question though about the Advance Pokémon Sprite Editor. When I attempt to open my FireRed ROM, I get an error message saying "data is not LZ77 compressed!" Can anyone tell me what I need to do to fix this? What is the problem and what do I need to do?

Thanks!

But I know how make extra 25 placeholder Pokemon fully avaible to catch. You need

1. ROM with added Pokemon <On places between 252-276>
2. Pokedex Order Editor.

When you are in Pokedex Order Editor check from 252-276> And check in HOENN DEX and NATIONAL DEX as numer 0. What that give? They show MissingNo. Pokedex Entry and do not crush game after catching pokemon.

Hi, I like your tutorial but I have a problem, whenever I try to add in the sprites with APSE, I can get it in, but when I hit write to rom I get this:
Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

Arithmetic operation resulted in an overflow.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

I have the latest microsoft.net framework and I am running windows vista, anyone know what is going on?
I have tried this with both Emerald and Firered and it doesn't work.

I got this issue too, but it was because my computer was running in Japanese mode. After switching back to English, everything worked fine again. So maybe some people need to set their system locale to English. Maybe this might help someone who also has this problem.

No matter what I do, I can't seem to sync up the palettes without manually editing it every time. But I am not changing any colors from the original sprites. Why is this happening?

Sorry for the double post, but I did end up getting it, but I found a new problem. Bye the way, I'm using Emerald. I edited the sprites, and then saved them. But the animations come out as just grey blocks for some of them. Any ideas how this happened, and how I can fix it?

EDIT: To avoid triple posting, I'll just edit this one. I'm trying to replace Swalot with Goomy, but the Goomy sprite doubles for some reason. It's just for the normal sprite though, not the shiny.

How can I add newly Pokemon without replacing any data?

Hey, I wanted to redo the pikachu sprite, but if I insert the page with pikachu with half of 1 ear off, it appears still after clicking okay, it only has one line in it (where I 'cut' off the ear. What should I do?

I found way to add new Pokedex Entries without ASM working. If you want i can share it with you here.

WHAT YOU NEED
FSF - For free bytes.
GBAPGE set <Important for this>


1. Unpack from rar GBAPGE and go to INI and open in texteditor rom.ini.
2. Change section PokedexEntryNumber from 387 to 412 (In rom which you want edit. Check by header. I test that method with Pokemon Ruby US <AXVE>)
3. Open Pokedex Entry Editor from GBAPGE set of editors and find your rom. You've seen some extra spaces under entry of JIRACHI.
~~ADDING ENTRY (Repeat steps for all new entry spots)
4. Open FSF and found two separated by 6000 bytes (Minimal interval is 3000 for it. But i take 6000 bytes to be sure that new entries do not crush game)
5. Repoint failure adresses from new entry <First entry was blank specie name and two invaild blank text phrases. Later entries have glitch text> To make sure that your new entry do not crush game.
6. After repoint edit WT and HT of new pokemon with Scaling and writing text under that.
7. Save rom first after edit WT, HT and Scaling and later after edit Dex info.
~~~TESTING NEW ENTRY~~~
1. Use Advanced map or another map editor.
2. Set all grass by ?????? on one from 25 places or for new Pokemon which you give into one of those places.
3. Open the game on Emulator and go to edited grass.
4. Catch placeholder/new pokemon.

And look for results. It show you picture of new Pokemon with strange footprint <Paw with ? mark> and your text under that <With edited WT, HT and species name>

But i do not found way to add new cry for placeholders Pokemon.

I hope that I help you.

THIS METHOD IS BUGGED. USE AT YOUR OWN RISK. -karatekid552

When I encounter the Pokemon, the game black screens and freezes. This has happened a few times now and I'm guessing I did something wrong. If it matters, I'm using Pokemon Emerald as my rom base.

why wont this work for me
I indexed my icon and changed it to 16 colours and the palette was black

lmao
