Here's a better ROM Invincibility, you can still pick up fuel with this cheat. Whoever hacked the ROM did a dirty hack for that cheat as it just changes the zero page address stores to another address.
Code: Select all
<cheat desc="Invincibility"> <comment>Don't run out of fuel/energy - so enable the infinite cheat for the best effect</comment>
<script state="on">
<action>temp0 =cartslot:cart:rom.mb@05FD</action>
<action>temp1 =cartslot:cart:rom.mb@0600</action>
<action>temp2 =cartslot:cart:rom.mb@062D</action>
<action>temp3 =cartslot:cart:rom.mb@02F1</action>
</script>
<script state="run">
<action>cartslot:cart:rom.mb@05FD=A9</action> <!-- Sprites -->
<action>cartslot:cart:rom.mb@0600=12</action> <!-- Sprites -->
<action>cartslot:cart:rom.mb@062D=A2</action> <!-- Background -->
<action>cartslot:cart:rom.mb@02F1=10</action> <!-- Background Bullets -->
</script>
<script state="off">
<action>cartslot:cart:rom.mb@05FD=temp0 </action>
<action>cartslot:cart:rom.mb@0600=temp1 </action>
<action>cartslot:cart:rom.mb@062D=temp2 </action>

Yes this is exactly what I was trying to make for a5200
You did it Thank you.

I think I got it from Atari forum it was old thread. Doesn't matter now. This is much much better.
