Coin options

[hobbyismater]

I finally got my bill validator to work and each dollar gives 4 credits and $5 gives 20. Which will work, but I really wanted to do .50 a song so in the coin options I see % but it's stuck on 1% how can I change this to 50% or can I change songs to take 2 credits?

I got this working, well enough I guess. I get 2 credits per dollar, cant give extra for $5 doing it the way I have to. Just need to figure out how to keep the settings, maybe install some kind of battery for memory is what I am going to try and figure out.

You dont need a battery to retain settings, I think settings are saved in a file, is it forgetting your coin op settings ?, might be a file permissions thing?, did you shut down the Pi correctly ?
