Hello - I have been using LaunchBox for a while and it's great. I ran into this problem though, when I try to launch a certain Saturn game (Radiant Silvergun) using LaunchBox (Mednafen core) it gives me this error message - "retroarch.exe has stopped working" but when I bypass Launchbox and start Retroarch.exe and select the game, it works fine. LaunchBox is using the same retroarch.exe, what could be the cause of this?
