That 4d one uses the same chip ours does. It has the same problems. To elaborate on the problems: audio quality isn't great, the part seems to go off the rails in its internal state machine, requiring a reset. It's hard to ensure that the audio file will work; sometimes it just...doesn't, for no apparent reason. The part only supports 2GB and smaller cards, which are getting scarce. That's not to say it's completely useless; obviously plenty of people get it to work or we wouldn't sell it. It's just a little hairy sometimes. Someday, when I've solved all the other mysteries in the building, I'll make one that doesn't have these problems.
