Converting a mame XML cheat to lr-mame2003 DAT

[RetroGamer_Dirk]

I am trying to manually convert a newer MAME cheat for TMNT, which does not exist in the lr-mame2003 DAT file to play on RetroPie, but is included in the newer versions of MAME (installed on my regular Mac). The XML cheat is:

 <cheat desc="Hit Anywhere">
    <script state="on">
      <action>temp0 =maincpu.mw@4725C</action>
      <action>temp1 =maincpu.mw@47292</action>
      <action>temp2 =maincpu.mw@472BC</action>
    </script>
    <script state="run">
      <action>maincpu.mw@4725C=6002</action> <!-- This ROM cheat was made by nolberto82 -->
      <action>maincpu.mw@47292=6002</action>
      <action>maincpu.mw@472BC=6002</action>
    </script>
    <script state="off">
      <action>maincpu.mw@4725C=temp0 </action>
      <action>maincpu.mw@47292=temp1 </action>
      <action>maincpu.mw@472BC=temp2 </action>
    </script>
  </cheat>

I know it probably begins like :tmnt: but mostly I can't figure out how to decipher the second part, the "how to poke" part of the cheat. Any advice?
