How on earth do you hack a game?

[Everyday Luma]

I have done some research about hacking games, and it seems like a fun thing to do (as opposed to getting a job with Nintendo.) But I have no idea where to start. What coding language should I learn? How do you access the game and start hacking? (I know how to install hombrew on the 3DS, but what next?). And a ton of other questions.

Programming a Game is much more complicated, than you may expect.
The only real way to learn to Program, is by pure practise.
It even took me a long time to just make this, and it was done with official Tools (no Homebrew).

But okay, my suggestion is, that you make a simple Space Invaders Clone for PC first, in C++.
Once you got it right, making another Game will become a whole lot easier.
Then you can work your way to the 3DS, and to more complex Games.

Each time you get stuck, use Google and StackExchange.
In the beginning, you'll need it every single second, I know that, I've been there at some point, also.
