It is important to understand that the IPAC is a highly capable board with several features that can cause undue challenges if not fully understood. We can follow the example of setting up an Ultimarc IPAC controller as a model for other keyboard controllers which may follow similar steps, but here are some specific details about the popular IPAC controller from Ultimarc.

These drivers are limited by the available GPIO pins.

On the Raspberry Pi, software such as Adafruit-Retrogame or GPIOnext are good examples of virtual keyboard drivers. This is like using a controller board above without the board.

It is possible to wire buttons directly to GPIO pins and then run a software driver that translates the input from the pins into keyboard keystrokes. In such cases, the board is not acting like a keyboard, but rather a gamepad/joystick. Note that some boards have a gamepad mode (or firmware) instead of a keyboard mode. Triggering a pushbutton actually just sends a particular keystroke to the computer. These often correspond the common key-mapping scheme used in MAME. The terminals typically have labels for the buttons/switches and player numbers that should be connected (Coin, Start, UP, DOWN, LEFT, etc.). Instead, they have screw-down terminals, header pins or solder pads to which you wire your own buttons.

Of course, as described above, a regular keyboard can also be hacked and wired to arcade controls, but there are better solutions: USB Keyboard Controller Boardĭedicated controllers like the Ultimarc IPAC series and similar USB interfaces are essentially robust keyboards without keys. At minimum, you would want to hold down a key after the first boot into Emulation Station in order to setup navigation capabilities (arrows for up, down, etc.). If you were only planning to emulate a computer-like maybe an Apple II for example-this would be sufficient.

The most basic example of a keyboard interface is just a regular PC USB keyboard which can be used as-is. Types of Keyboard Interfaces USB Keyboard These devices are built to overcome the problems with hacking actual keyboards. A popular solution is to use a dedicated keyboard controller designed for arcade emulation. Hacking inexpensive keyboards in order to build arcade controls can reveal issues like ghosting (problems when pressing too many buttons simultaneously), or interaction delays that you might not notice when typing but that will ruin a gaming experience. Functionality when typing is not the same as the requirements for multi-player gaming. Hacking an actual keyboard is still done today, but going this route can lead to problems. It was possible to build an arcade cabinet from scratch using real arcade controls and wire them to a computer keyboard and play emulated games. They could run the wires to actual arcade parts (joystick switches and pushbuttons) which were available from manufacturers for servicing actual arcade systems. A standard set of keyboard keys was quickly established to serve as the typical inputs to common hardware controls (Insert Coin, Start, Up, Down, Left, Right, etc.).īefore long, some enterprising individuals realized that they could pop open their computer keyboard to gain access to the circuit board and solder wires to the key switches. As more arcade hardware was emulated, systems often had similar controls. In order to emulate the movements of a joystick, pushbuttons, coin insert, etc., specific keys on the computer's keyboard were used.

In the early days of arcade emulation, MAME was running on computers which, naturally, have keyboards. Usually, a keyboard interface is wired to arcade buttons which introduces another layer of abstraction to your configuration and additional considerations when you are trying to troubleshoot controls. In principle, a keyboard should be the simplest, most traditional interface to understand, but in practice, a keyboard is rarely used as an actual keyboard when playing games. Using a keyboard as a controller for emulation can be very easy, or it can be challenging and complex depending on your specific hardware and design needs.
