Xpad for Atari ST

Xpad is an open standard for extended controller input for the Atari ST family, by Neil Rackett

Introduction

A small, transport-neutral shared state block that exposes every button, stick and trigger of a modern gamepad to native ST software, enabling you to create custom drivers for modern controllers.

See README.md for more information about adding Xpad support to your software and creating custom providers of your own.
