Okay so i just got my gateway, I also got another 3ds with 6.3 firmware to play pokemon on, I've heard that the the secondary cartidge is a clone r4, after i install the exploit on my 4.5 3ds can i use the kart on my 6.3 3ds as a r4 for nds games and such or will i still the the DSTwo (or whatever its called sorry) to do that?
