Hello, Bare with me regarding these questions. I've read a lot regarding the 3DS flashcard that actually play 3ds ROMS. Currently i own a DSTWO which is a bit outdated and thinking of upgrading to Sky3DS or Gateway 3DS. I'm leaning towards the Gateway but i have some questions that I need answers to first. 1. The Red Gateway is for 3DS and the Blue for DS? 2. Can I also play DS games or even Gameboy games? 3. I also heard about Sky3DS but I know that this does not support DS games at all. True? 4. The Sky3DS also supports online gaming. Does Gateway support that too and how? 5. If I have an upgraded 3DS 9.5 (as of now) can I downgrade it through Gateway? 6. If the said system is 9.5 and there is a new Gateway update, can I update it from there or I need a 3DS with older version firmware? If there is an older post that answers these questions please point it out. I searched but I got more confused in the process. Thanks in advanced.
