Let's say that you already have a Nintendo DS/i on your hand and ready to use:
You need:
* A Flash Cart (i highly recommend DSTWO)
* A MicroSD Memory Card (up to 32gb is supported.)
* A Card Reader
* A PC/Laptop and Internet Connection for downloading games and required files
Process of installing backup games in NDS:
- Go to the flashcart's website and download their latest kernel.
- Copy the Downloaded Kernel files to your memory card.
- Then after that, Just copy your NDS ROMS anywhere on the cart (do not copy/place any roms on kernel's system folder)
- Remove the SD card on your computer and place it to your flashcard..
- Place the flashcard.. loaded with the SD card you used earlier. And Voila.. Enjoy..
