Main UI of the program works in DOS/shell console.
Graphics display emulation requires SDL2.
Makefile are included to build under Windows 32/64 (mingw compiler required)
and under Linux Ubuntu or Ubuntu based distro.
The best way is to download source code of SDL2 and build it.
Makefile-s are included to build under Windows 32/64 (mingw compiler required)

To build under Linux:
* Make sure C++11 compliant version of GCC compiler is installed.
NOTE: Under older distros, e.g.: Ubuntu Server 12.04, the newest c++
compiler installed may not be modern enough. Follow instructions
