none of your examples are Nintendo DS games, but I love the trend from that era of giving games on that system names which abbreviate to D.S. (much like the Super prefix or 64 suffix from those respective console generations)
- Castlevania: Dawn of Sorrow
- Advance Wars: Dual Strike
- Mr. Driller Drill Spirits
There aren't so so many of these but enough that I noticed it when I was younger and thought it was clever haha
