I had an e mail from someone that could not get ZINc working with MAMEWah. And we worked out that there may have been something missing from the Configuration of ZINc. He managed to get it working in the end with the help of ZINcFE.
Because ZINCFE writes all the config files for ZINc he had no problems getting ZINc to work with MAMEWAH.
So find a copy of ZINcFE get zinc working with that, then use my page to set up ZINc in MAMEWAH and everything should work

I had ZINcFE set up on my PC before useing MAMEWah. So I didn't have any trouble with it.
