I found a blog from Team Europe, a dumping team that focuses on preserving more obscure game consoles that most would'int care about with one of them being the V.Smile. I'm specifically referring to this post showing off an Auduino device that let's you dump V.Smile games among others like Leapfrog carts.
That post also mentions some games uses two chips for the data instead of one, which are older grey carts, and games that take up more space like with Toy Story 3 on the V.Smile.
Here's a link to that post which has everything you need to get started dumping your own V.Smile collection.
