How do I make a NES patch?

I kinda wanna upload my old NES SMB hack onto here, but apparently, I don't know how to make NES patches.

There are a bunch of utilities to use for creating NES patches here. Just search for them in the Utilities section.

LunarIPS is pretty straight forward. Works well for me.
