All codes in official database don't work in both gigandes and gigandesa though except "Infinite Credits".
Old gigandes was renamed to gigandesa and gigandesj to gigandes in 0.147.
So you need to swap gigandes.xml for gigandesa.xml.

Fixed "Invincibility".
gigandes.xml

Code: Select all

    <cheat desc="Invincibility">
        <script state="run">
            <action>maincpu.pb@F00B8D = maincpu.pb@F00B8D | 20</action> <!-- flag -->
            <action>maincpu.pd@F00B5C = 00000002</action>               <!-- timer -->
        </script>
        <script state="off">
            <action>maincpu.pb@F00B8D = maincpu.pb@F00B8D band ~20</action>
            <action>maincpu.pd@F00B5C = FFFFFFFF</action>
        </script>
    </cheat>

gigandesa.xml

Code: Select all

    <cheat desc="Invincibility">
        <script state="run">
            <action>maincpu.pb@F00B95 = maincpu.pb@F00B95 | 20</action> <!-- flag -->
            <action>maincpu.pd@F00B64 = 00000002</action>               <!-- timer -->
        </script>
        <script state="off">
            <action>maincpu.pb@F00B95 = maincpu.pb@F00B95 band ~20</action>
            <action>maincpu.pd@F00B64 = FFFFFFFF</action>
        </script>
    </cheat>

Merged old "on" and "off" codes into one.
Added status flag address to enable/disable flicker. (Bit 5 is flicker flag)
Adjusted timer code. Game program checks value of timer is plus (>=0) or minus (<0).

This uses flicker. I confirm one side-effect that player body doesn't displayed in taking off scene.
I post another invincibility by ROM code without side-effect here.

Code: Select all

  <cheat desc="4th Unit Mode">
    <script state="run">
      <action>maincpu.pb@F00B87=05</action>
    </script>
  </cheat>

What effect does "4th Unit Mode" have? I can't confirm any effect for this code.
