Patch for Mario and Luigi Bowsers Inside Story

I know that a lot of people are asking for a patch. But I need help from someone that has currently patched the game using an EDGE card that can give me a step by step process, that is easy to understand. I dont understand the whole process of patching a game.
Your help would be great.
Thank you.

Follow the instructions
It tells you how to patch in everycard of NDS :)
Just focus in what type of card you use.
