![]() The switches in a single package will generally be connected to consecutive bits in an input port. Most arcade PCBs use packages of eight DIP switches, as they can be conveniently connected to an 8-bit input port (this isn't always the case - Bally Midway MCR uses 10-switch packages). In almost all cases, pushing a switch up switches it on (i.e. When you're looking at the DIP switches "right-way up", the switches will be numbered from left to right, starting at number 1. They generally come in packages of four to twelve switches. This makes them convenient for use with automated PCB assembly system. ![]() ĭIP switches (Dual Inline Package switches) are small banks of switches, with the same pin spacing as integrated circuits. Here's a picture of a DIP switch package. On top of this, there are cases where the game is buggy, or the manual is wrong. Also, some game manuals do not cover different regions or versions of the same game, so the settings should be checked in game to verify the manual is correct. What these switches do can be determined by looking at the game code, reading the game's operator manual, or by just adjusting the DIP switches and observing how the game runs differently (this method is usually not enough to figure out what most switches do). Some games will not run or will display wrong colors if DIP switches are not set correctly, so figuring out what these unknown switches do is helpful. DIP Switches can be viewed and set in game by pressing TAB and going to the menu marked DIP Switches.Ī large number of DIP switch settings are not documented, and thus marked as Unknown. For more info and pictures of DIP switches see the Wikipedia article. DIP switches were used by arcade games to allow settings like difficulty, cost per play, number of lives, etc.
