Function showSpringboardScreen(item as object) As Boolean  
port = CreateObject(“roMessagePort”)  
screen = CreateObject(“roSpringboardScreen”)

print “showSpringboardScreen”

screen.SetMessagePort(port)

screen.SetContent(item)  
endif

screen.SetDescriptionStyle(“generic”) 'audio, movie, video, generic  
’ generic+episode=4x3,  
screen.ClearButtons()  
screen.AddButton(1,“Play”)  
screen.AddButton(2,“Go Back”)  
screen.SetStaticRatingEnabled(false)  
screen.AllowUpdates(true)  
screen.Show()

downKey=3  
selectKey=6  
while true  
msg = wait(0, screen.GetMessagePort())  
if type(msg) = “roSpringboardScreenEvent”  
if msg.isScreenClosed()  
print “Screen closed”  
exit while  
else if msg.isButtonPressed()
