fMSX is a famous emulator of the MSX, MSX2, and MSX2+ 8bit home computers.
It runs MSX/MSX2/MSX2+ software on many different platforms including Windows and Unix.
See http://fms.komkon.org/fMSX/ for further informations.
It has been first written by Marat Fayzullin, and later Vincent van Dam ported it on SDL.
Here is a port on Dingoo/Dingux of the version i've previously ported to GP2X-Wiz.
How to use it ? Everything is in the README.txt file.
It's distributed under Marat Fayzullin's license for the original MSX part,
and under GNU license for all the GP2X part.
