Hello my friends,
Sorry for the  latter  reply, i was really busy, 
and  thank  to Floyd for  your comment, in the past  my frontend  was Hyperspin, but  because  i met everytime a new bug i leave it completely.
so, unfortunatelly, i never succeeded with any recomandation ....      
 
   i tried what you told me PinealServo, 
 Set-ExecutionPolicy -ExecutionPolicy RemoteSigned  (on the 2 version of PowerShell i have, but game won't launch  and  retroFe logs dosen't  help much more.
So, i had the idea to create  an ahk script :
the idea is quite simple but even there, i didn't succeed to make it work. (i have  not enough knowledge to make it work),  i passed lot  of time to read on autohotkey forum or on the internet and  made a lot  of tests....
the script must kill a cmd.exe process (or close it) when the  escape key is pressed (and  permit the exit of the game).
one  example  of ahk that i tried :
#NoEnv
#SingleInstance, Force
#Persistent
;launch the game : you need  to know the ahk_class : run AU3_Spy.exe to know it
Run, StreetFighter 4 Arcade Edition Export.bat									
;if windows ahk class is no more existing, --> apply the following instructions:  
IfWinNotExist, StreetFighter 4 Arcade Edition Export		
;stop (exit) one instance of cmd.exe; take care if there are other instance, only one instance will close.     
 Process, Close, cmd.exe 
;exit the script  --> avoid to keep it runing on background								
	  ExitApp   											
Returnyou must understand that this  is one of my test, of course  i tried  with for example :
Esc::Process, Close, cmd.exe 

but in this case,  the cmd  is closed immediately, 
often it is like because the  game  is  in fulscreen, the command  within the ahk are not executed..........
i tried  lot  of code  with IfWinActive, IfWinExist etc..........     no succes!
is there  any expert with ahk somewhere here?   

the best ahk would be  an ahk script that only kill the correct cmd (or at least a cmd process on the exit  of the target game exe).
see you
