Just ordered the R4 in the green box with a 2gb micro SD, just wanting to know any info on this atall like is the interface simple and easy to understand? Is it really drag and drop with .NDS files? Will save files work with this? Can i emulate other games systems such as snes with the R4? Is there really 100% compatibility with any game as its said on the box or do some have trouble? pretty much any info you can give me from your experience with this device will make me much more confident in my purchase. Running this on a DS lite also
