Hi, I'm a bit confused on playing Roms online through gateway. I have a MBP which stores most of my gateway roms. 1. Which programs do I need to use? 2. Where do I get headers to inject? 3. Do I need to use emunand? 4. Can I download DLC for games like fire emblem awakening using the online functionality? 5. Can I play animal crossing online starting a new save?
