Quoted from pinballnut3:been looking for g-5 for a month now.
I got the G-5 rom for my FT from a pinsider that goes by the name "romman". I dont think, however, that he has been on the site in quite a while. His name is Stephan and his website is: hobbyroms.com. I would try to reach him through the website. He's a very nice guy. Good luck!
