I have this card:
it was working fine on my 3DS for playing DS games. I just updated the FW from 3.xx to 4.5 (from shin megami tensei iv) and now the r4 card will not load.
I believe I need to update the card itself to work with 3DS 4.5 but not sure how this is done. tried looking for the patch files for 4.5 but cannot find any.
the official website: http://www.r4idsn.com/download.asp only has a patch for 3DS 6.2:
3DS6.2 patch is released now!(for R4iDSN 3DS card only)(Aug.06,2013)
can use some help
