Cant get any games to start on any emulator

Hello, new here. I loaded Retrobat and really like how its setup. But no matter what settings I tweak in the emulation station I cannot get any game to work properly. I have changed the video driver on several platforms, Atari 2600, 800, Colecovision and a couple of others. I can get the game to start but its just a black screen. I hear the game running sound wise.

Been combing this forum but not finding the right answer. Any help would be much appreciated.
PC Specs:
Windows 10 Pro 64Bit
Intel Core i5-2400 CPU
16Gb Ram
AMD Radion HD 7450 Video card


Thank you!
