I can launch Dreamcast games only if Flycast is already loaded

On Linux, I cannot launch Dreamcast games from the DC playlist or from the “Load content” menu, I get a “core dump” and RA crashes. The only way for me to launch DC games is to load Flycast first, launch it without a game, get back to the RA menu and then launch a game. This is the only way to get it working. What can I do to make Flycast launch a game without having th launch Flycast first ?

that’s weird well i use “redream” but first i compress the games using “qchdman” to “create cd chd from file” using the “gdi” file. after i just search the chd file of dreamcast game and i start the game using “redream”
