Hacking Emulators For PS3 Running HEN on 4.87

[gonefishing1975]

I have installed HEN for my system that was stock firmware 4.87. I installed HEN for it and have Retroarch working with Atari 2600, Nes, Snes and Sega. I also have multiman working with games from an external usb drive. My questions is why on;'t the stand alone emulators for Nes, Snes or Sega work? I get a black screen and have to unplug the power or an error code. Any ideas?

Thanks
