I know the GW 3.0 ultra is excellent for 3ds 9.2 , you can just load through SD card pre-loaded the launcher.dat and use the bulit-in browser to visit go.gateway-3ds.com to enter GW3.0 Mode, but I was thinking about if we're out of wifi connection(such as you are on train, bus, outings), how can I play 3ds games easily like sky3ds with plug and play?
