After doing some research, it looks like the Nintendo Switch Lite doesn't support DS games. This is primarily because the Lite model doesn't have the two-screen setup that was a key feature of the DS. Also, the Switch Lite doesn't have a cartridge slot for DS games. So, if you're a big fan of DS games, you might find this a bit disappointing. But, remember, the Switch Lite still offers a vast library of Switch games to enjoy!
