I kinda wanna figure out running the software before I do a proper writeup on cohost, I know there's a way to use her like a webcam, and considering there's just a generic usb webcam inside I think there's a chance you can just switch her to mjpeg webcam mode
In general I'm pretty impressed with this toy, the camera isn't great but she takes two standard AAAs (they're in the legs lol) and the controls are dead simple. Sturdy build too, obviously still a wild concept for a video camera but not too bad to shoot with in practice (would be nicer if she could stand up on her own but I don't think that's a feature Barbies have). I like the outfit, the oversized hood to hide the monitor while you play is fun
