Originally Cygne was developed by Dox as a Bandai Wonderswan (Colour) emulator for Windows systems. From version 2.1 Dox decided to release the Windows sources to the public in GPL form which allows others to use the source and hack it :) Cygne/SDL is a Cygne port using the Simple Directmedia Layer (SDL) library. Cygne/SDL is released as OpenSource under the GPL license. It uses code from the orignal Cygne (allthough a bit modified), code from the MAME NEC CPU core as well as portions from several SDLemu emulation projects. Anybody may hack the current sourcecode if they like or can make additional changes into it.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
