Don't worry about zerog line or any other, only "patch=" lines matters, some others are just there to describe the codes and other stuff.;3 Also the pnach file formatting got changed slightly, that guide is based off old version and use old programs as well;3. To make it really easy we use "omniconvert"(google for it) and PCSX2CE(at tools section in this forum;3) to easily convert/format cheats into pnach files.

You can deactivate any code by commenting it out with //, or just copy those you want.
Also when you create your pnach file, make sure it has correct name(same as your game crc, without 0x ofc) and no hidden extenshion added(pretty common "problem";3, windows hides known types, and people often have there .txt added after saving in notepad as text file).
