goncalodoom said:in my opinion supercard team has a lot to work,so many unplayable games,slowdowns,and lag and saving issues,i recomend sticking with Snesmulds and wait for a new release of NDSSFC
Try getting this http://sites.google.com/site/mog123x/snesadvance.dat and putting it in /NDSSFC/ and /NDSSFC/system and see if that helps any. Even without that, Final Fantasy 4 (japanese with the translation patch, not in the .dat) looks full speed to me. Also be sure to set the CPU speed to 4, I don't know why they even bother to set it at 2 by default as it is way too slow.
