Quoted from Bigkahuna707:Does anyone know of anyway that I can get the custom ROM (high speed L4 rom just with words change to reflect the Monster Rancher theme) burned? I would be great if I could just send some one the file and they can burn it and send it to me.
I think this is what you are looking for: ActionPinball (www.actionpinball.com) will copy a ROM to a chip for you, if you provide the file. You can email them to ask them about the service (it was $15 plus $8 shipping for me).
Good luck with the project!
