Add New Pokemon In 15 Easy Steps!

I'm sorry to add onto the load of questions, but when I add a new Pokemon in the ?????? slot (after Celebi), I try to load up the game (FireRed rom) but the emulator just shows a white screen. I've triend browsing the internet to find an answer, but all I got was 'change save type to Flash128. So I did that and... nothing happened.
Help anybody?

hhmmm... not sure did you download visualboyadvance? that usally lets you play hacked pokemon games.
 
Does anyone here have experience using unLZ with wine and a Mac? I used TP's method to insert a custom trainer sprite before, but the same method won't work with a pokemon sprite. There shouldn't be too much difference, right?

I've done everything listed, but unLZ just spits out a message that says "Image is not indexed." I'm not the most hacking-literate person. Any suggestions?

Hmmm....make your image indexed by decreasing is color depth to 16bpp and keeping the first color as the background color of the image... :)..

May sound hard for non experienced once in hacking..
 
I changed the sprite for Treecko in Saphire, along with some of it's attributes, but whenever I pick it as my starter, the screen freezes and goes into negative colors. Help?
 
Okay, so now I'm having a real problem. The Treecko I replaced has the color scheme of what I'm replacing it with, but it is still shaped like a Treecko. Any help? Thanks.
 
Hey, is it possible to do this on an nds rom, I have searched and searched for guides but to no avail. If it isn't, than damn it, but if it is possible please tell me
 
so then, what about the pokedex entries????

i'v added 2 pokemons, its succesful working, theres just one thing, when chaugt its shows a ratatta next to it. becuase of the entries. and the pokemons cant be found in the pokedex

Do you think using a tutorial from 2009 in 2016 is a good idea?
It's not.
We don't 'add' pokemon like that anymore. See my signature for EM Pokemon adding. For FR google Pokemon Expansion Fire Red.

I have heard that the rattata apearing when catching a pokemon can be fixed by giving proper habitat to the added pokemons.... just look at my signature.. i have a tutorial on editing habitat for added pokemons...
its a hex editing though :)

oh great, i will try it out!
 
I know you can add new Pokemon in the GBA roms by using the question mark slots after Celebi, but that's only 25 new Pokemon. Is there anyway that I could possibly add all of the Pokemon from gen 4,5, and 6? Maybe even 7?
NEVER use those 25 slots for anything except a Givepokemon, a Givegg or a Mega Evolution.
They're NOT normally usable because they lack proper Pokédex data and making them usable is pointless.

With that being said, you can use Karatekid552's Gen III Hacking Suite or Gamer2020's Pokémon Game Editor to expand the amount of Pokémon in your ROM.
 
Thanks for these links! I'm trying to use the Pokemon Game Editor, but when I try to click on the Pokemon Editor button, I get this error: System.OverflowException: Arithmetic operation resulted in an overflow. I can technically still use the program, but I'm worried this might mess it up somehow. (And if I'm not supposed to talk about this program in this thread, could someone kindly guide me to one?)
 
Ok so i try to add some pokemon and i started with chikorita...all of the tutorial was going pretty good up to the point i had to work with unLZ-GBA. it doesnt work at all. I tried to put in the 3rd sprite i made but it said error the image is not indexed. So i added the 2nd one. However after hitting write in rom and writing the numbers i got in fsf it started not working. This means it continuously threw me out of the app saying that it isnt responding. Anyone having an idea according to what i can do??? And plus i read that you can only add up to 25 new pokemon. Isnt there a way to add all the pokemon of all generations?? (my aim is to make a pokemon game having all the generations in it.

For that all Pokemon question, I asked the same thing before. I was directed to this thread, and it worked for me: https://www.pokecommunity.com/threads/380296

I can't answer your sprite question, though. I've been having the same problem.
