Sorrow's Furnace Mini-Pak

have download the pak but i dont know how to put it in game,
Can anyone help me please....

If you have downloaded it and run the small exe that is the initial download, it's been put into the game for you. You can tell this by going to the options menu, where you'll see a DS icon down in the bottom right. If it's colored, it's playing the music from directsound, if not, it isn't.

uhm.. so can you make it play ingame??

i can run the .wma files in media player. but don't really wanna do that..

will it only run when you're in the sorrow's furnace area?

Correct, the music is linked to specific areas in the game, when you visit those areas, you get the new/high quality music. If you don't have the directsong music for an area, then you'll get the normal music shipped with the game/area
