Flycast : games start only in Retroarch Desktop UI mode

Hi,

I’m trying to use flycast_wince core, and my game launches only in Desktop UI mode (using Retroarch 1.7.7 on Windows 10).

When loading content from the “standard” UI, nothing happens though I can see retroarch.exe in the process list.

When launching Retroarch, switching to desktop UI and then launching my game, everything is ok and the game runs fine.

I’ve tried both flycast and flycast_wince with the same issue. My video drivers are up-to-date.

Is there anything I’ve forgotten, or am doing bad ?

Thanks for your help.
