I cannot do this no matter how hard I try, Ive went into sysnand virtual and found the save file for the Pokemon sapphire vc, and when I try to inject my save file from mGBA it says the injection failed. The only time I had success with the injection was when I edited the sav from sysnand virtual and then re-injected it. Does anybody know if maybe with PKHEX you can merge save files without changing every little detail by hand? And if not, does anybody know how to make the VC sav and mGBA sav compatible so that one can replace the other?
