You used *all* of them? Really? That's impressive... So, you tried ALL the NES, SNES, N64, GC, Dreamcast, PSX, PS2, Genesis, Master System, Atari, CD-I, Virtual Boy, Intellivision, 32x, Sega CD, Sega Saturn, NeoGeo, NeoGeo pocket, and Turbo Graphics 16 emulators (I'm sure there's some I forgot. Help me out here)? You've got a lot of free time on your hands...
I think what you actually meant, though, was that you tried all of the N64 emulators. If that's the case, do you have a 3D card? What operating system are you running? What happens when you try running the emulator? Does an error message come up? If yes, what does it say?
Beyond that, I don't know how to help you. Your question is fairly vague. Mouser X over and out.
After I encountered a new plugin, called Rice Video 6.0, I tried it out, but only sound is working, and all I see is black. Another error popped up, while it said "No fragment shader support". What does it mean?
