This is a Pokemon Game I don't think it'll be released anytime soon, but we currently are working on it for both PC and hopefully working on CellPhones. Its going to either be based off FireRed, or Emerald. But it should be very very fun after release.
It's going to be a ROM file so its going to be saved as a (.GBA) file.
So you'd have to download VirtualBoy, or some other GameBoyAdvance Emulator.
A GameBoyAdvance Emulator is a program you download and you can play GameBoyAdvance games on your computer. But you would need a ROM file which you locate the game you want to play, like Pokemon FireRed. You search and download the ROM file on the internet and enjoy playing it.
This ROM tho, I'm hoping to have it work with CellPhones that have Apps on it, like the Androids. My Android phone has an App on it that lets me play ROM files, so I download ROMS and open it with that App on my phone, and it's amazing!
Sincerely,
