Non MAME Emu Snaps

[upprc04]

I am currently setting up the machine that I'm planning on using for a cabinet I'm hoping to build.  I have MAME and NES snaps.  I was able to download the MAME snaps, but had to create my own NES snaps.  To do this, I created a batch file to run every rom I have, wait 5 seconds (to hopefully get through all the initial screens and to Splash Screen or Demo gameplay) and take a screenshot.  I was planning on doing the same thing with my SNES roms, but ZSNES and SNES9x isn't playing nice.  For some reason, ZSNES won't take a screenshot when I simulate pressing the screenshot button.  And when I take a screen shot in SNES9x, it is all garbled. 

My question is where could I download SNES snaps or has anyone gone through the same process to get snaps for SNES or other emulators?  Has anyone ever had the issue when taking screenshots in SNES9x and they come out all scrambled?  If I could solve that issue, then I should be able to use my batch file or adjust it to get all my SNES snaps.  Of course, I'm taking a chance that I actually get a screenshot, but I wanted to get some basis and I can always go back and tweak the batch file to try to take screen shots at different intervals.
