I'd like to seek advice and help. 1stly this 3DS that I could purchase from someone is installed as above on a 4.2 1st gen 3DS. 2nd I'm only purchasing the handheld itself without the gateway card. 3rdly I have a 9.8.0 3dsxl with sky3ds blue button 1. How do I verify it is even 4.2 or modded to 9.8.0 gw3ds? 2. What are options if I do purchase the handheld?Purchase a gateway card?
