Hi everyone, I'm new in 3ds CFW and homebrew. I have slight idea about homebrew. After searching through this forum, I found some thread similar with my case, but they are different, so I decided to create new one. Alright in my case, I have old 3ds LL (japan region) with firmware Ver. 10.3.0-28J. I do have MH Generation and MH4U cartridge (US Region) and I have install homebrew with menuhax. My goal is, 1. import/export save data from MH Generation After I installed homebrew on my 3ds, I can run MH4U cartridge with region free app. But once I try to go to online, it shows error 003-0399 and kicks me to offline mode. my question are, how to solve this problem? I have read other thread, it says about config.cia but with homebrew only I can't run cia file. second question, how to import/export save data through homebrew? Thanks for your help, and I appreciate any help.
