Abstract

A cross-platform development system includes a computing device that generates an image of an operating system, and a software development peripheral connected to the computing device that runs the operating system corresponding to the image. The software development peripheral communicates information, such as image data, generated by the operating system back to the computing device where the information is displayed on a display device connected to the computing device.
