The screen will also display the VID:PID (the USB ID) of your controller. * ENTER to end the mapping without mapping any further buttons (keeps maps done so far)

* SPACE to skip a button (that button will remain undefined) * ESC to cancel the mapping operation and return to menu See below for a more technical description of each step. * Button to turn on mouse emu (and to use as “sniper” mouse mode) * Controller buttons to use as mouse buttons (left, right, middle) * Alternative directions (also used for mouse emulation) * A button or a 2-button combo to open the OSD * A, B, X, Y, L, R buttons to the MiSTer gamepad (see image above) * Choose what to use for directions (can be D-Pad, any analogue stick, or even buttons) * Test D-Pad and analogue sticks (effectively a joystick calibration) This information does not contain any physical information (which button is “A”, where it is located…) and you may want to decide which buttons to specifically assign for each function. Each controller is recognized by a unique USB ID (VID:PID) and declares what it can do (does it have d-pad? how many buttons?). MiSTer uses USB HID to handle controllers. You can override it by re-doing a mapping from inside a core. This step is exclusively handled in the main startup menu. You can also ignore the analogue stick as long as you do not use the few cores that require it (e.g. MiSTer internally recognizes more buttons (and two analogue sticks), but the above is the minimum required to work on most cores. Here is a conceptual representation of the MiSTer Gamepad: * A few extra buttons for advanced functions (more below) * OSD button or 2-button combo (to use instead of F12 on the keyboard) * Four face buttons and two shoulder buttons * Test the D-Pad and analog sticks (if any)

MiSTer will then ask you to assign several buttons to your controller:

This is done in the menu shown at startup.Īfter plugging a keyboard, press F12 to show system settings and select “Define joystick buttons” The first step is to teach MiSTer to recognize your physical controller. If needed, you can override at any time per core (and per controller) via OSD menuġ - Mapping of MiSTer gamepad into cores has two “flavors” of operation, chosen by INI file.MiSTer gamepad is mapped automatically to cores 1.Define centrally a physical controller into a virtual “ MiSTer gamepad” (+ extras).MiSTer has a simple three-step mapping system:

Before using any controller with a MiSTer core, it must be defined in the main menu core MiSTer’s mapping system ¶
