If you see a TikTok or YouTube video promising a QR code that installs a full, paid DS game onto your 3DS or DSi for free, be very skeptical.
Here is what usually happens:
While not a "direct" QR install, you can scan DS game QR codes with your smartphone. The code will open a download link in your browser. You save the .nds file, then manually drag it to your SD card. This is slower but works 100% of the time.

Nintendo never implemented QR code game distribution for the DS or DSi. The confusion stems from two separate but related technologies: If you see a TikTok or YouTube video
Thus, when users search for "download free DS games QR code," they are likely hoping for an easy, one-scan solution. In reality, the process is more involved.
With Nintendo aggressively protecting its IP and the DS eShop long dead, it is highly unlikely that QR codes will become a legitimate distribution method for DS games. However, two developments could change this:
Until then, QR codes remain a gimmick in the DS emulation space.
