Gens & Mamewah help

[FLAPS]

Everytime I post an issue I know I'm one step from finding the answer and it's probably a real noob like problem to ask for help on but meh I'm a noob so help 

I've been playing around with Mamewah today with mixed results so far. I have Nes and Mame stuff set up fine but now I'm trying to run GensFE with Maemwah but whenever I boot the game through Mamewah it drops me back to my desktop with one corner going black and the games music playing but the game isn't actually visible. I looked around for help with it using google and the only piece of advice I found was to put "[rompath]/[name].[romext]" in the default options section in the Gens ini file but that didn't fix it so now I really have no idea. I'm using Mamewah_v097 and using the Mamewah set up tool  if that helps anyone work out what the problem is. Thanks in advance for any advice.
