As far as i know this does not work on any r4 flashcarts or third party that use r4 software like wood version or such.
I got few flashcarts and my ace3ds,acekart,and r4 dont work.
But android emulators and ds emulators on pc works fine for me.
So dunno what would cause issue unless its an error that a flashcart only sees.
Hopefully they can test it with flashcarts or find the underlying issue with flashcarts or just play game on pc and android.
Edit: tested the acekard with admin settings and disabled dma settings and now it works. With dma settings on game won't work. So turning dma off fixed flashcarts issue.
Apparently all flashcarts and having dma issues with the game why doesn't work.
