Review on 2021 SDHC 8GB Micro SD Card with YS Menu Installed - Compatible with DS, DSi, 2DS, 3DS, DSi XL, 2DS XL, 3DS XL by James Gregg

I was worried it wouldn't work on my system because I keep updating it, but it works perfectly! I was also surprised to see that over 700 Super Nintendo games are included in the emulator! Of course not all of these games worked and I deleted them all anyway to make room for more DS games but still a nice shot. Oh, and you have to insert the r4 cartridge into the game slot in a specific way to make sure it's all the way there. You can feel it and it's pretty easy to do, but you'll see what I mean when you try it on your DS for the first time.
