And where can I get these magical things called soundfonts?

Some retro ones here -> http://woolyss.com/chipmusic-soundfonts.php#soundfonts (right click the SF2 or ZIP icons and "save link as")
You'll need a soundfont player to use sf2 files, bs-0 is the only free one I can think of for OSX -> http://www.bismark.jp/bs-0/index.html
