Hi, 
 
	I try to start my Dreamcast Game and it won't start in launchbox with the retroarch Flycast core.It was working before and I don't know why it doesn't start now. all My Games are in .chd or .cdi format
 
	
 
	The name of the platform is the same in retroarch config.
 
	I tried to replace retroarch.cfg by default one but it doesn't work at all. 
 
	When I try to start a game directly in retroarch, it works perfectly.
 
	I don't know what to do. Any Idea ?
