Help me with hacking.

I've been hacking Zelda 3 for a long time, but I still don't know how to hack the game.

I know some ASM but not very fluent in it.

There is also a new editor, I don't know how to use it.

I need someone to teach me how to code and how to make a game from scratch as well.

I'm a video game designer yet don't know how to make a game.
