download a Pokemon gba ROM and no$gba
There is a fanmade Pokemon Cursed Black version on cartrige, however there is a rom you can download (i can not find the website again, I will improve the answer when i do find it, sorry)
I am not sure, but I've heard that there isn't one. notice the 3d aspects of the Pokemon games. that would be extremely hard to make an editor for let alone actually editing it. Keep looking for one, I am.

Yes there is
Just by using tools.
with hacking tools
If you're talking about fake Pokemon games on the computer that you play with an emulator, than most people use map editors and change scripts to manipulate the game for their purpose. A simple way to do this is to download an emulator like Visual Boy Advance, which can be downloaded from the related links section here and other sites that provide emulators. Then you download a Pokemon game ROM for a game like Pokemon Sapphire from the related links section and other sites that provide ROMs. Then go to the GBA ROM editing tools link below which has tools for editing the ROM. This page is will be in Spanish, though the tool names will be in English. From this website you can get all the tools you need for editing things like wild Pokemon, towns and routes, text spoken by characters, and pretty much everything to create fake (3rd generation) Pokemon games.

I suggest using Nightmare editor. It allows editing of the ROM so back your ROM up
Advance Map is only for editing the Pokemon ROM. You can't edit Pokemon data with it. That's how they made it. There are other programs that can edit Pokemon data though.

Google to look for the answer, its out there. But like most hacking tools, you load the ROM and go from there, provided you use the proper ROM the tool requires.
