hey guys so i just picked up one of the ATgames Mega Drive HD's the later model without the red bit from what i understand and its lacking the about and SD slot menus in the main menu, obviously i wish to load my own roms onto it and was hoping someone here could advise/help me on how to progress, i have downloaded the firmware from the main site and a supposed CFW but i don't seem to have a way to load it onto the system.
