First give our online demos a try. This is the easiest way to try JPC! There are all Java applets that will load within your browser, and allow you to play some old DOS games.
We also have a stand-alone version of JPC available for download. The JPC application allows you to run JPC directly on pretty much any Java (J2SE) enabled device. It contains JPC bundled in an executable .jar file along with a Freedos floppy disk image. You can also use your own disk drive images! Please see the JPC Application Instructions for step by step details on how to download and then run the JPC Application.
JPC is Open Source, under the GPL2 licence! It's easy to build if you are familiar with building Java applications from the command line (makefile included).
