Preferences for Jasmine are currently only available for Mac OS X.
Preferences for Jasmine can be set by selecting the Preferences... option from the Jasmine Menu.
Show Intro at Startup: The value of this checkbox indicates if the Jasmine Intro file will open when Jasmine starts.
Use AltiVec: Selecting this option will tell Jasmine(TM) to use the AltiVec extentions of your computer hardware. This can make sound effects (such as pitch or length alterations) much faster.
