How do I load my floppy disks and games like df0: on an sdcard?

Amiga games for example, most have been converted to boot on an sdcard instead of a floppy. Basically, the whole disk is converted to what is known as .adf format or <gamename.adf>. If you put whatever game(s) you want to play on an sdcard  and then select this from the Replay OSD menu under the Floppies menu say df0: then depending on if you have just booted your replay into the OSD menu directly or after hitting the reset option on the OSD with a .adf game loaded into the df0: floppy option, it will start whatever game is in the DF0: selection automatically.
