thanks! this works in this way: if you press start p1 in menu, it give you 1 credit (only if you don't have credits) and start the game (1 credit is consumed). if you press start p2 in menu, it give you 1 or 2 credits (only if you don't have needed credits for 2 players) and start the game for 2 player (2 credits are consumed). You can add more credits if you press startp1 or startp2 in the game time or in the menu configuration.
