My PC Speaker actualy works perfectly. The beeping sound that comes from your computer's inside, yes!
There are some games that work perfectly on Windows XP withOUT DosBox, such as Wolfenstein 3D. It has got good PC Speaker effects, just like Street Fighter 2 on the PC does, and it also runs without that program. Even Kings Bounty runs, while its an 1990 game.

But LotusIII and Grand Prix Circuit doesen't. Both had amazing PC Speaker music

So, is there ANY way to make DosBox use my real PC Speaker, and NOT emulate it? I love DosBox, but why would you emulate something that you already has? It makes no sence...
I even got an MP3 Player for the PC Speaker, I would test it in DosBox, but you know how it goes... I wanna hear from my real PC speaker...
