I can't get a SNES emu to work

I'm on CFW 5.00 M33-3, and I can't get a single SNES emu to work, I've even followed a couple different "how to" videos on YouTube and couldn't get anything to work. Is there a reason for this? I got my Genesis and GBA emu to work just fine, but I can't get a working SNES emu. Anyone else run into this problem?

yeah, the same problem for me, i'll try putting my "snes9xtyl" in a GAME5XX folder, and my"snes9xtyl%" in the GAME150 folder...
if i have any luck, i'll tell you...
