I can't seem to get this to work correctly. I am putting the smsGGoo.sim in the GAME folder of the Dingoo but it isn't recognizing or showing any of the SG-1000, Game Gear, or Sega Master System roms. I go to Emulators (Interesting Game) to look for the roms. I am using POS custom firmware. Could the firmware be my problem? Any help would be greatly appreciated.
