Welcome to the PokeCommunity! Aw it sucks that you don't have a 3DS, what were the last games you played? Hey, it'd be cool to see your pixel art, feel free to make a gallery over in the
Art Studio. Our forum also does have a lot of resources and people who can help you out in building a ROM hack, you can find all that over in the
ROM Hacking section. Good luck, and have a great time! :D
