If your game doesn't launch normally (white/black screen), here's a tip from the Discord community: Fullscreen is currently buggy as hell on both Windows and Linux. The only stable solution at the moment: use a config that already has windowed mode enabled. Download the file from the link and move it to AppData/Roaming/HyperDemon/ (for Windows) or steamapps/compatdata/1743850/pfx/drive_c/users/steamuser/AppData/Roaming/HyperDemon/ (for Linux). For Goldberg Emulator, the path to this file may be different. At the moment, one patch has been released (the previous one is being distributed here), but, as far as I know, this problem has not been fixed in it. I can't test it myself, because I didn't have this problem.
this is practically devil daggers but getting high
