Mame and Permanent Cheats?

[Candiman]

Quick Question

There a few games in which I would like to have some cheats always on.
As to be able to play hidden characters in fighters and turn timers off in other games in 2 player mode etc.

Is there a way in MAME or by editing a rom for example so that certain cheats are ALWAYS enabled without having to go through mame's menus?

Thanks

I think this works:

Open cheat.dat in notepad. Find the game and cheat that you want permanently enabled, and just put a : at the front of that line. Close and save changes to cheat.dat.

sorry for openings such an old subject but i dont really get where to edit stuff.
I want to skip Operation WOLF having the flash on each bullet so this is what I have in my opwolf.xml in MAME}cheat\cheat.7z

  <cheat desc="Stop Screen Flashing on Shooting">
    <script state="on">
      <action>temp0 =maincpu.mb@001131</action>
    </script>
    <script state="run">
      <action>maincpu.mb@001131=02</action>
    </script>
    <script state="off">
      <action>maincpu.mb@001131=temp0 </action>
    </script>
  </cheat>

I dont understand where to add this : or is it another way of do this nowdays?

The cheat system updated over 6 years ago to use LUA scripts.   

I'd look for more recent info and/or Pugsy's posts here.
