can someone show me an example of the "old-format pnach files"?

[opplft]

in the "cheats" section of game's proprieties . the cheat section tell
"This section allows you to select which cheats you wish to enable. You cannot enable/disable cheats without labels for old-format pnach files, those will automatically activate if the main cheat enable option is checked." 

but none on internet explained what is the "old-format pnach files" . knowing that format we can finally activate and deactivate each individual cheat

You can see old format from old patches in the repo
