Code: Select all

  <cheat desc="Maximum Start Level Selection">
    <script state="on">
      <action>temp0 =maincpu.mw@90CD</action> <!-- BCC $90C9 -->
      <action>temp1 =maincpu.mb@9001</action> <!-- Rom Checksum -->
      <action>temp2 =maincpu.pb@0126</action> <!-- Level Completed -1 -->
    </script>
    <script state="run">
      <action>maincpu.mw@90CD=EAEA</action> <!-- NOP/NOP so the compare condition not met, listing all selectable levels -->
      <action>maincpu.mb@9001=D1</action>   <!-- Changes ROM checksum so it passes test -->
    </script>
    <script state="off">
      <action>maincpu.mw@90CD=temp0 </action>
