Virtual Jaguar is software dedicated to emulating the Atari Jaguar hardware on
a standard PC with Windows, Linux and MacOSX operating systems.
Here's info about upcoming release:
Some fairly major changes are coming to Virtual Jaguar in the DSP handler. It should give better performance (and sound!) on multi-core systems. Assuming all goes well, this will be included in the upcoming 2.1.0 release. Plans are also in place to add a few remaining missing things, such as full screen capability and gamepad support.
