The game in question is Osu! Tatakae! Ouendan (remade into the western game Elite Beat Agents). It's basically a fun rhythm/action game where you're required to tap and slide on the touchscreen in time to the on-screen prompts and thus control a team of male cheerleaders who go around encouraging people with problems.

Here's a link to a trailer and there are plenty more videos on YT if you search on the title.

It's free to a good home, but I would ask that you pay to cover the shipping costs (and seller fee on Paypal transaction) - probably no more than 4-5 US$ or equivalent.
Condition on cartridge, box and manual is near-mint. The game is region-free, so it plays fine on my Euro DSi XL for example.
It's a Japanese game so you'll either need to be able to follow Japanese text or to enjoy the "poking and hoping" method and not knowing what the heck is going on.
Prior experience of Elite Beat Agents would be a major advantage but there are some useful mini-guides on GameFAQs and the core gameplay is pretty simple.http://www.gamefaqs.com/ds/928590-osu-t ... endan/faqs
