Ha, I didn't even realise I had a C220B fitted in mine; but then if i'm honest I have no idea how this stuff even works. I presume the coin detection is down to the coin mech and the credit board just reads what coins were inserted and passes the info back to the game?
What coin changes have we seen lately aside from the new pound coins? Didn't the 5p and 10p coins also change?
If so then I guess I need to configure it to use 20p's and 50p's.
No idea how though - not configured one of these things yet.
