If you are lucky enough to own an original GBA cartridge for one of these games, you can play this with a GBA, a Game Boy Advance SP, or a Nintendo DS. Failing that, though, there are ROM Hacks that you can download online, and with an emulation software or app, you can play these games on most modern devices like your smartphone or PC. Or, you could go for the more modern remake of these games titled Pokemon Alpha Sapphire and Omega Ruby. You can play both of these titles on the Nintendo 3DS.
