Sourceforge has been running ‘project of the month’ for a while now, and  DOSBox won out!  It is the second time they have actually won.  For those of you living in a cave, DOSBox is a fantastic PC emulator geared at emulating not only early PC’s of the 1980’s and early 1990’s but also includes its own MS-DOS like operating system for running ancient video games.  It also has been ported to numerous platforms, including Java, Android, OS X, Linux and of course Win32.
DOSBox is also used by some big companies (steam, gog) for the continued sale of old MS-DOS games. Â Who says old won’t sell?
Anyways there is an interview with the primary authors on the sourceforge page.
