Bluecardfix sysnand or Emunand?

Hello there,

I want to install bluecardfix to use my old acekard2i again on my 9.0 n3ds. I have rxmode set up. Should I install bluecardfix in sysnand or Emunand? And to destination nand or sd? And will it run in Emunand or do I need to enter sysnand to play the acekard?

Thanks!
