I just got my Acekard 2i, I installed it with AKAIO 1.4.1 - and then I threw my old .nds and .sav games I had before for my R4 from my DSL. However, even though the .sav are on the card - all the games I've got work, but there are no recognizable save files. Then, I noticed when I had gone back to the Acekard menu, there is my old .sav files, and then some new .nds.sav file... What do I do to get my old .sav files from my old R4 to work? Do I need to rename them .nds.sav? I've set the system option to nds/sav/backup , I've set it to NDS + SAV , and I've set it to ALL, nothing works? I'm also using the old microSD that I had been using in the R4 as well, my SanDisk 2GB.
