How do I use a Yume Kira Bag?

[dazzilitchigirl]

I've ordered the blue Yume Kira Bag, and haven't actually received it yet, but when I do, I'm sure I'll have questions about it and spend ages looking for a guide to it. So, I'll just ask in advance - how do I use the Yume Kira Bag? What does it do? Are there any accessories I need? How do I play the game(s)? I don't need a really long and complicated guide; just a simple paragraph or two about which buttons to press and
when, or even just the features you think a non-Japanese-reading person would find difficult.
