There are two versions of Cygne.
Standard - 'Cygne.exe' , and  with simple debugger 'Cygne  debugger.exe'.
The second one is for experienced users which are familiar with WS hardware and x86 architecture.
Program loaded into debugger version is stopped after reset. Just click Run/Stop button to get it working.
You can also execute it step by step  and/or watch registers and disassembled code (when the "debug"  option is checked).
Durning emulation you can press (in both versions)  keys 1,2,3 and 4 for different cpu timing. 
Also keys 5/6 increase/decrease number of cpu cycles executed in one scanline.
Key 'P' is mapped for pause/continue  function and key '9' is for take a screenshot and save as .bmp file to 
directory from where last file has been loaded.
