http://youtu.be/j_5RWxHHVvE dragon83: Thanks, got it. I have another question. In the video you show that how can you setup Munt for Wing Commander Academy. It is easy, because it has a sound setup for the GOG version. But what if a game has no sound setup. I'm talking about Betrayal at Krondor, which I'm trying to play with Munt? Can I set it up elsewhere?
Gydion answered it for this particular game.
For others, it depends on the game!
If there is a INSTALL, SETUP, SETSOUND you need to launch that with DOSBox. Others are missing the INSTALL like many Sierra games, so here you edit RESOURCE.CFG or other config file like in Wing Commander. So basically, every game is different :)
Best to check in the forum of whatever game you're playing.
