Need a title for selling nintendo ds games on ebay?

I really want a new jacket but don’t have the money so I’m selling my ds games.
I have 16 games including an r4 revolution card. On the r4 card there is 54 games.

So in the title would I say Bundle: Nintendo Ds games. 69 games or
Bundle: Nintendo Ds games. 16 ?

Or any other alternatives you can think of?
Are r4 cards illegal ? I bought it from amazon.
