Launchbox don't start Dreamcast Games with Flycast core in Retroarch

[yontala]

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 ?

Same issue here, started when I updated Retroarch to the latest version, all paths seems correct and games run fine when using Retroarch directly
