Three questions My cousin's R4 broke on him so i bought him an acekard2. I'm not there to set up the card for him but i managed to have him download the 4.13 software from here and extract it to the root of his micro sd. Is that all that is needed? Will the SAV files from the R4 still work or is there a way to convert them? Is the interface on the acekard similar to the r4 and easy to understand for a 9 year old?
