For those bronies who love pokemon, I recommend getting this for your GBA emulator. A fan use a Pokemon FireRed™ ROM and use sprites for the ponies along with some text changes as well. Each version have 3 different starters. Twilight Sparkle, Rainbow Dash, and Pinkie Pie are in Dawn Edition and Fluttershy, Applejack, and Rarity are in the Dusk Version. First you need to download winRAR to extract the files, then down below is a link to the GBA emulator to play it on. Finally, Download the ROM itself. All of which are FREE. Just make sure to drag the ROM files from the RAR so you can locate and play. It's a really fun game!
