Homebrew DS Repro Cart Link?

[Parax342]

I have looked for DS repro carts and I cant find any. (I mean the kind with hidden SD slots that autoboot a single game, not traditional Flashcart)

OR

How do I modify a flashcart to autoboot a game

 

[PRAGMA]

Those are just flashcarts with the kernel setup to autoboot the last played game, if you change their firmware to r4 wood kernel, it will play just like a flashcard.
