After reading through the Plailect guide and also forumer's comment, can anyone point the correct direction for me? I have read that if we do a region change, we will not be able to access the e-shop anymore. I have 2 N3DS 1) A9LH 11.2.0 N3DS (US) 2) normal 11.2.0 N3DS (E) Since I don't have one of the four listed DSIware, "DSiWare Downgrade (App Injection and Second 3DS)" seems to be the only way for me. However, the source N3DS (running A9LH US region) has a different region with the target N3DS (normal N3DS EU region). So I would have to do a region change on source N3DS before downgrading the target N3DS. i) Using the region change guide to change my source N3DS with A9LH to EU region https://github.com/Plailect/Guide_RedNAND/wiki/Region-Changing ii) Buy a DSiWare game on the target N3DS (since I've already changed region, I will not be able to access the e-shop so what are the alternatives to this)? iii) proceed to downgrade following the guide. any help or suggestion is appreciated!
