I have an original 2ds, the flat one. I'm new to this, just wanted to know what's the best way to download roms for my 2ds and do I need some sort of launcher for it. I don't want to jailbreak my 2ds, i just want to add games to my sd card for R4 and play them. What file type, what menu and also 3ds games are playable too right? Are they the same file type? I got this r4: R4i SDHC Renovation V2.10T

Just want some advice before I do my own research and digging, could be useful.
