i'm trying to help my friend merge the data between 2 SD cards. one SD card is the 2GB one that came with her 3DS and has Mario Bros 3D Land installed. and the other one is a 32GB one with Bravely Default Demo, Pokemon X patch updates, and PokeBank. the first thing i did was backup both cards separately to a computer- "old card" and "new card" next, i formatted the 32GB to tidy things up. i then copied over the "old card" data first to the card. then the "new card" data. i was prompted with a replace for a "00020400" folder. and i selected yes. and agained prompted for replacing "phtcache.bin" within this folder. and again i selected yes. when i boot up the 3DS, i only see the "old card" data of Mario Bros 3D Land. should i not replace this folder and the file?
