We got one of these toys a couple years back, and it was basicly a step motor w/ a pen to design images to be put onto a doll parts.
Fisher-price/Mattel has discontinued this product, no longer supporting the software that needs a patch that locks the product from continuing to working;
I'd love to reverse engineer this product and possiably make a software to interface with it; i'm also not above just replaceing the existing board with a mcu/sbc and writing 2 instead of 1.
How difficult of a project would this be?
