I did, but i only have one game to try it with, I don't have a bunch of DS VC games like others do. So i can't really try it with others. The one i did try, had not worked, and i dunno every flash cart firmware file except for wood firmware. And Dstwo. I did try the homebrew in the dsemume before trying it on Loadiine but again, only one game to try it with. Wish i had more games to try but i am not rich.Why don't you try it out for yourself?
Download NesDS or Gameyob, and try to do a quick inject using NDS2WiiU or a similar app.
Then try to boot the result VC through Loadiine.
It's worth trying!
Give it a shot!
I didn't try GBA injections cause it had mentioned something about python or some thing i don't have.
