Hehe, I'd love to have PC Speaker sounds incorperated into AGS. It's the same thing used in MI1&2, Maniac Mansion (original)and other very old games. You could make the sound of a door opening or a clock ticking without taking up a mass amount of memory! I don't know about you, but, when used properly, can be very useful and retro. But when misused, it's just cheesy ;D
This discussion has just been had not too long ago, I think cj said it would be too damn hard to do in windows....
