Great addition. I love this custom firmware set
It's very nice not having to navigate all the way down (from the 'interesting game'/'emulator') to open roms on your inserted sd-card.
Most of us will have all their games on the SD.
As the internal memory of the Dingoo A320 is fairly smaller then the optional SD-Card, most of us will have their roms on the optional storage.
I use the internal memory for changing content (Music/Videos).
