I was not having any luck getting gensFE to properly run my roms through mamewah. I was hearing the sounds of the game, but no visual. I posted this question on another thread, and this is the simple fix. I'm more or less putting this out here for noobs who do a search in the future.

Before I found it, I entered a code straight into gensFE and it worked outside of mamewah. Once mamewah started the emu, it ran about five thousand miles an hour. Being a noob, it only took me five days to figure out that the frame rate had been changed and it can be fixed through the menu bar in gensFE. I know this is not much info to the regulars, but it may help a fellow noob solve a headache.
