Fruit Machine Chat

I've been asked to look into changing two rainbow riches, from category D to C.
How would I do this, is there a switch or does it need an update?
Any help would be very much appreciated.

You need a switchable stakes and prizes key. If its all Double Dutch to you, check out an MPU5 manual for Horizon cab, assuming its the pub version (three square boards on top glass) and not the lo tech.

sorted, just went into options and changed it, didn't think it was going to be that easy
