You guys are in luck!!
I had massive problems with ready-made .ini files for MAMEWAH and a lot of people seemed reluctant to post their .ini files. Others just couldn't identify problems. However, after a bit of tinkering I identified some problems with the file and modified it slightly. Turns out the 'executable commandline format' was wrong!
Stick with ZSNES, it is brilliant once it is working. Just make sure you get the modified version from the cpviewer website (jcrouse's) which enables 'Escape' to exit the emulator, rather than call up the menu.
One problem I had with it was the speed, which seemed slower under MAMEWAH, but isn't really. What I found though was I had a delay between button presses and the action on screen. No-one could explain it, but in the end it turned out to be as a result of triple buffering in the 800x600 resolution I had it in. I shut this off and it was fine! Here is my .ini file. All you should need to change is the 'rom folder location' and the 'emulator executable location':
