The SIO2SD device for the Atari 8-bit range is a fantastic piece of kit, allowing you to run software from an SD device on your Atari. It's difficult for a new user to pick up though, so I put together some instructions to try and make things simpler:
File structure:
Place the Loader file in the root of the SD card, ensuring it is called: sio2sd.xex
Create a folder called ATARI that contains all of your files in whatever directories you wish.
Loader Instructions (v3.5):
ARROWS/JOYSTICK: select directory/file (.xex) or disk image (.atr)
RETURN/FIRE:...
