When I get to the game it automatically asks me if I want to uit the game and always when I press "N" it asks me again and I can't get into the main menu at all.

Does anyone have this problem?

I recommend using a source port for playing Wolf3D or Spear of Destiny.

Please read and follow the links at https://www.gog.com/forum/wolfenstein_series/helpful_wolfenstein_3d_sourceport_and_discord_links accordingly.

When I tried to launch Wolf3d, my Dosbox would launch and then immediately terminate. My solution was to switch to DDraw rendering. It works only when you switch to DDraw from a different renderer, so when I want to launch the game again, I switch to OpenGL fail a launch, then switch back to DDraw again.
