So far, stand by is working great. I have it set up to never shut off the hard disks, which wastes power a bit, but I can shut it down if the cab stops getting played a lot. The only problem I'm having, and I'm blaming this on my computer (1.8 pent 4; 1 gig ram) is that Mala quits if I use UmuMovies HQ vids for the screensaver link. I switched to stills and it works fine. Also, task manager seems to give Mala a hiccup sometimes. Mala switches to 100% PC usage and sometimes causes a crash. That's also probably not related to stand by. Other than those things are running great.
+1 on just tapping a button and having Mala pop up a second later. To me, it seems more like an arcade when you're able to play right away.
