Try this:
1. Make a new folder and copy of your mame folder's contents. Don't copy folders only the files under "c:\mame"
2. Delete the the files in "c:\mame" that you just made a copy of.
3. download and open the zipped mame file. copy the contents of the zipped file to your "c:\mame" folder. remember you do not need to copy the folders contained in the zip file.
4. goto the "Start Button" the "Run" type "CMD" then hit enter.
5. goto the "c:\mame" folder and run "mame -createconfig". This will create your "mame.ini" file
6. now edit the .ini to point to the correct directories and set your other options.
now go and try running the rom using the command line method. If that works then try mamewah.
