After nearly an hour of toying around my files, I must say I am deeply thankful gringe. Even though it led to me getting a violation earlier...

So playing Binding Blade, I eventually came across the same problem numerous people suffered in 11A, where the game freezes after selecting conquer. The ROM I got 6 from was BAD USER NO LINKING TO ROMS, and from what I've read/everyone I asked in other places so far, I am to move my .sav file to a Japanese ROM. Thing is I don't have a PC (the one I had broke) so I have to resort to Android. I can find my .sav and other files easily with ES File Explorer, and I have Unipatcher, but I just can't figure out how to get my save file to a Japanese ROM, to then in turn move it back. Any help please? What exactly should I be looking for? What should I be patching/patching with?
