Tool: Pokémon Gen III Rom Hacking Suite

If you want to expand Advance Map to show up all your expanded pokemon in the wild editor:

1. Download HxD and install it
2. Open Advance Map .exe in HxD
3. Go to address D027C
4. You see 9C, that's 156. Don't worry, this is the end 156.
5. After that you have 28 extra entries (after Chimeco), bad egg (1), all unowns except for A (27). Then you have to add the amount of pokemon you added to that number, for instance 10. Which makes it 38.
6. Add the 38 to the 156. This makes 194.
7. If the above number is above 255, you have to use a different method.
8. Go to and scroll down, find your number (for instance 194) and read what's the hex, in this case hex C2.
9. Change the 9C in C2.
10. Save it and open Advance Map.
11. You can select your pokemon for wild pokemon!

Ok so it depends on what OS you have. If you have:
Windows - Gen_lll_Suite.Windows-.English.Encoding.zip
Mac - Gen_lll_Suite.MAC.zip
Linux - Gen_lll_Suite.Ubuntu.14.04.zip


I don't really know what the Chinese one is for, but I doubt you have it.

Chinese is more for Chinese people I think or people who have a Chinese system, it uses a different encoding than English (which is most likely UTF8) and for that your program might have to be remade for the encoding.

Not sure though, but that's the biggest problem of different encodings. Sorry if I'm wrong...

Not sure about Sapphire (or LeafGreen for that matter, haven't tried though), but you can definitely use it on Ruby and Emerald. Only downside is, you won't get things like the Pokémon expander as that is for FireRed only. Haven't tried adding new evolution slots, too.

I had this happen recently to my front sprite pointers for ??????????, Bulbasaur, and Ivysaur. Essentially your pointer has been overwritten by other data and is now trying to load invalid data.
Copy down the hex values given in the error, then open up your rom in a hex editor and search for them. Then go to a Pokemon that you know has a valid sprite and click "change pointers to images" and copy down that Pokemon's front sprite pointer. Put that number into pointer format (pair up the numbers by twos, put them in reverse order, then stick 08 at the end, i.e. an offset of 0x123456 becomes 56 34 12 08 in hex), and in the rom replace the invalid pointer from the error with the working pointer. Once you have a working pointer you can go into G3HS and import/repoint the sprites again, which should work properly.
Looking more closely, in your case it actually looks like an pointer rather than corrupted data (because it ends in 08) but for some reason isn't pointing to an image correctly. In any case the above solution should work.

This is a pretty handy tool, but if you're already using a-map 1.95 and don't want to downgrade you can just put placeholder Pokemon in A-Map's editor and then go to the map's wild Pokemon table and edit the placeholder Pokemon's index number to the number of the new Pokemon.

Good day. It seems that I can't open my rom nowand having this error. At first, just by changing the number of move by 512, i could open it. But now, even I edit the number of move by 511 i and correcting the right number of moves i still get this error.

Sorry for the trouble and thanks!

I recently found out about this tool, and attempted to open it. However, I get this error:

15:08:44: This is not a PNG file.
15:08:44: Failed to load image from file "Resources\IconTiny.png".
Click to expand...

I checked - it is indeed a PNG file. Furthermore, looking up the error itself lead me to believe that I need to copy some files over from a folder named "dist"...which I do not have at all.

This is a Windows 8 laptop; is it compatibility or something else I'm doing wrong?
 
Hola amigos y fanes pokemon, perdonen las molestias de ante mano
solo queria saber si con esta herramienta se puede ampliar el pokedex y si los pokemones agregados pueden salir en el juego de manera salvaje y con otros entrenadores en modo batalla
graxias de antemano y disculpen las molestias pero soy nuevo en esto...
 
I keep getting errors like this when clicking on any Pokemon past Arcanine to edit.

Can you please help?
