I've searched, but I couldn't find anything specific to my problem. I switched from an AK2i that just couldn't keep up with the 3DS updates (read here that it would never be compatible again), so I bought a couple R4i 3DS Gold (rev C) cards for me and my wife's 3DSs. I got them from ZhuZhuChina (yet another recommendation from here) and they arrived within a few weeks. I downloaded the latest Wood kernel, as well as flashing to the most current firmware. Everything works fine, except there is no existing savegame data when I load a ROM. I did find this old thread that said to rename the .SAV files to .sav, but that didn't work: http://gbatemp.net/threads/using-old-r4-save-file-on-new-r4i-gold.202480/ What am I missing here? Have I really lost all my savegames, or is there a way to recover/convert them from whatever format Acekard used to something the R4i card will recognize? **EDIT** I just noticed that the games I tested actually had a compound extension (*.nds.sav). I'm trying to add the .nds before the .sav on all my old files now.
