Hi Tony
Having the ROM file is sadly only part of the mission as it was a CART based game, this means it would need to be decoded to work like a GDROM game.
As far as I am aware nobody has done this with the WR image, I don't even have the image myself so cant test to confirm, if it has been dumped recently or specifically for you needs it may not be ready to go.
If you can send me the file I can take a look on my setup and confirm if I can get it working or not but getting it ready for the weekend might be a hard push.
