S2000 - disable adding credits with the service button

[clading]

I've got an S2000 with a standard Bettor Tito board installed and it's all working as it should. If you press the service button, it adds credits. Is there a way to disable that feature from the menu options? I've read that it's a feature you can get or not with the Tito boards and that it can be disabled, but no one says how to do that. I am positive that I've made that change on other machines with the upgraded Bettor Tito board, but can't for the life of me remember how I did it or where I found the instructions on it. Can't find them now anywhere.

disable legacy bonus on the keychip menu I believe.

Yep, that was it. I was comparing two machines and saw System Bonus Legacy on them both and was thinking the System Bonus was set to Legacy. When I key chipped the machine, I realized that it was the name of the setting and not the actual setting itself. Set the System Bonus Legacy to Disabled and it works perfect. Thanks for the help. Dumb on my part.
