Last hack was soldering my PS1! Do not want to damage daughters 3DS. She still likes her Dad!! I have a few ROM backups for DS games, which I would like to run on the 3DS for her from 1 cart. 1) What card? 2) What download? is it called a kernel? 3) How do I know what V software she has? Does it matter! (only interested in running backups of our DS games, as she is too young to play the 3DS games yet). But more importantly if I get this wrong is there any risk of freezing the 3DS?! Googled but cant find a dummies guide! , Shes too young. I'm too old! Thanks for helping a newbie!
