No feedback on Windows when running chip8.exe

[danirod]

No stdout, no stderr, no error message printed if just .\chip8.exe is executed.

No stdout/stderr is because of -mwindows, which is a flag required to treat the application as a graphical (Win32) application instead of a console application. The deal is that unless the application is graphic, Windows will suck stdout/stderr and not print it to cmd.exe (MSYS shell works fine here).

No errors mean no feedback. If the user just double clicks chip8.exe icon he won't notice what is going on because there is no way for telling the user what he is supposed to do (drag a ROM icon to the application?, provide an argument via terminal?).
