I have just got an LDK retro game console emulator and I am trying to download more games to play, I have tried to download ROMS and put them on an external Micro SD card but it was unsuccessful. The Micro SD card has been formatted and is 32-GB, I have no idea how to download extra games, 
It would be helpful if anyone could tell me how to, any replies would be appreciated .
