Help extracting save from repro platinum cartridge

[Raedalus]

I have a repro platinum cart and the save doesn't work with anything. God mode 9 on my 2ds shows no .sav file, and the txt says that the save type is none. Somehow I can still dump a save, but it never works. Any save dumped through checkpoint is 0 bytes and any save dumped through gm9i gives a corrupted data error in pkhex. Is there a way I can read this save or dump a readable one? (if this isn't the place to ask, please redirect me to somewhere I should)
