Hi, i have some quick questions about cfw on a japanese 3ds with firm 5.0 , please help me understand if you can. 1. I read that i dont need a gateway or ds flashcard, is that true? 2.I could install cias with cfw? And can they be of different region? 3. Does the system play eur and us region retail cards with emunand? 4. Do games of 4.5 work or can games with higher fw requirment work like pokemon y or omega. 5. And lastly is it stable or will i have problems and lose savegames etc. Thank you very much.
