So we have a New nintendo 3ds and a 2ds, they both are running on firmware: 10.7.0-32E. - Is Sky3ds+ the right choice here with these systems running on this latest firmware? - Can i easily switch the Sky3ds+ between the 2ds and New 3ds consoles and play right away using the same flashcard? - Can i play all 3ds games as well as DS games and even gameboy roms? - Is there anything i should know before buying? Cons? I hope someone can answer these 4 specific questions. Thanks in advance!
