Marky, as a suggestion, you could make life easier and get better support if you update to the latest software first. The whole Mamewah config system and command syntax has been changed. People like me may have trouble trying to remember how old software works.
I recommend that you download the latest MAMEwah (v1.62b13) from jcrouse's site and use the files I posted in the other thread. It should work very easily then.
http://mamewah.mameworld.net/downloads.htmFor mamewah 1.61 this will probably work but I can't test it. The following assumes that you are using the "zinc.dat" and properly generating a game list with full game names. It also assumes that you are using the controller config files I posted earlier.
In your zinc.ini for Mamewah, Change your emulator command line to read (cut & paste):
emulator_executable c:\Zinc\Zinc.exe
Then change the command line format (next line) to read (cut & paste):
commandline_format [name] --use-controller-cfg-file=c:\zinc\ini\[name].ini{nodosbox}{safelaunch}
If that doesn't work, then update mamewah to the latest version and try again.
