Ok Folks the us DSI works with the Acekard, and on top of that the saves from r4 and super card load (after u remane them)
Example your rom called:Soma Bringer.nds the save would be renamed to Soma Bringer.nds.sav
now the way I did it was to go under:My Documents/Tools/ folder options and select file types then select new and type in .sav and hit ok, next select advanced and check the box always show extensions.(do the same for .nds)
now when you look inside your r4 or supercard you will see the name of the rom with the file extension .nds and your save file .sav, now just rename your save file to the exact name of your rom with the extensions .nds.sav
now you have your new dsi with all your existing save intact.
also if u want to put music on an sd card and play it on your new dsi do this:open itunes(down load it if u don't have it, it is free) make sure the song u want to convert is high lighted.
now right click and select create AAC Version(dsi only plays AAC Files)copy these files to your sd card and enjoy
