I can run Dreamcast games perfectly in either Retroarch or Flycast emulators alone but when I run those emulators within Launchbox the games slow down, noise crackles, and the games are generally unplayable. game emulators work fine in Launchbox, even Retroarch with other cores (e.g. n64, Sega CD 32X, etc.) but specifically the issue is with Dreamcast games. Any suggestions?
