Won't create memorycard files

[redleader225]

I recently downloaded dolphin v4.0. Every game i try to play says that there is no memory card in slot A or B. I have gone through all the files are there are no memory card A or B files. I have checked the GC folder and there is no memory card file. I have tried reinstalling it, ive installed different versions of it. I cannot find a way to get it to create a save file so I can save my game. Even if I try to continue into the game without a save file once I choose start without save it just resets to the title screen. The main games I am trying to play are Fire emblem radiant dawn for Wii and fire emblem path of radiance for GC and neither will save. Is there something I am missing?

Thanks

it'll create one if you set it to a folder with no memory card.
