I suggest you buy r4 card for ds lite and TF card from http://r4i-3ds.com, it provides free install latest kernal and games service. It’s out of box, don’t need any settings. It’s upgradeable, don’t have trouble back at home. It is for falshcard + TF card orders paid via westernunion.
You can request them to download the games you like after you finished the payment.
