[Mamejay]

Hi everyone,
i am wanting to get myself a Super Everdrive but I am wanting to know the main advantage of the USB model.
I really just want to play games and be able to update the OS.
If there any real advantage of the USB if I am not working with Homebrew software or didn't want to do anything but play games?
Thanks

USB version only for development. this version have not any advantages for usual gamers. so just for play games non usb version is a best choice. update os you can on standard version also via from SD card
