[Cap.Jang Game] 4.Can NDS run Gameboy cartridges? /Nintendo DS ( DSでGBが起動できる？任天堂 )

As far as I know, Gameboy Advance runs Game boy cartridges and NDS runs Gameboy Advance cartridges. My research is NDS -> GBA, GBA-> GB 

So I made a hypothesis of NDS->GB

Both Slots(not sluts ;;) are same but there was a small obstacle and I removed. Zelda was sacrificed for this experiment. I cried for him.

But it didn't work. 

FAILED
