I have recently downloaded a Soundfont (*.sf2) file which contains the Sounds and Instruments used in the Super Nintendo games. Every time I find a link in the Forum or User Tips Section, it always says that I need a soundcard called SB Live!! Where can I get this? If I have to pay anything, is there a trial version for at least 1 month?
The SB Live is a hardware card. You won't be able to download it. The SB stands for SoundBlaster, which is where you can learn more about it: http://www.soundblaster.com
Right. You cannot "download" a SB Live. It's a type of sound card manufactured by Creative Labs.

Go to your local computer store and purchase one, if your computer can handle it. Creative Labs is the leader in sound cards. If you ever purchase a Sound Blaster Live, you'll have a top notch sound card.
