Great Evening to ALL. These are My first KONAMI machine’s, and I need help PLEASE. I have a “ADVANTAGE 5†& a ADVANTAGE +. Both of them had low battery messages. I replaced batteries and now I have Error/message #725, “BACKUP DATA GAME ID MISMATCHâ€. I read through the the post’s and it was stating that I needed to do a “ram clearâ€. I’ve done plenty of IGT & BALLY machines, but NO Konami’s. I was able to download a pretty extensive manual on the games but, I didn’t see/understand the clearing process. There were CLEAR,SET & COMBO chips available. I also read something about an “EL†key. I would like to get some knowledge as to what I need to obtain to work on these machines. The way that this VERY ENJOYABLE hobby is going, I will probably work on more of these down the road. If anyone has any suggestions for me, I would appreciate it. THANK YOU, for your time and assistance, Dan.
