Old 3ds xl fw. 9.2 1. Im on gateway emunand will it be deleted. 2. Do i have to format my big sd before doing the customization or is it ok to continue without formatting the sd.(full format including emunand) 3. Will i still be able to use my gateway redcard. 4.Is class 4 big sd ok to use on customization or do i need a higher speed sd. 5. How important will the internet be while customizing.(slow internet) 6. Its been more than a year since the last time i used my 3ds, i found out that somehow i used rxtools when i was editing my legit cart of pokemon y and omega ruby. Will that affect my custumizing. Forgot how to used it anymore. Thanks.
