+    (description "@code{bsnes-jg} is a cycle accurate emulator for the Super
+Famicom/Super Nintendo Entertainment System, including support for the Super
+Game Boy, BS-X Satellaview, and Sufami Turbo.  @code{bsnes-jg} is a fork of
+@code{bsnes} v115, Many changes have been made post-fork:
+@itemize
+@item Higher quality resampler with settings
+@item Improved performance without loss of accuracy
+@item Portability improvements
+@item Removal of accuracy-reducing hacks and unnecessary code
+@item Significant increase in standards compliance
+@item Translation to the C++ Standard Library (ISO C++11)
+@end itemize
+
+In particular, it uses much less @acronym{CPU, Central Processing Unit}
+compared to the original @code{bsnes} (though not as little as @code{zsnes}).
+
+The supported file formats are:
+@itemize @file
+@item .sfc
+@item .smc
+@item .bs
+@item .st
+@item .fig
+@item .swc
+@end itemize
+
+This is intended to be used with the Jolly Good Reference Frontend
+@command{jollygood} command from the @code{jgrf} package.")
