Why the result of these two different cheats are identical?

Why the result of these two different cheats are identical?

Post by invincibility »

Hi Pugsy,

Now I'm working for the cheats of IGS games.

In the game kov2 I found these two types of cheats have identically effects:

<cheat desc="Infinite Energy PL1">
<script state="run">
<action>maincpu.pb@818909=40</action>
<action>maincpu.pb@D0906D=58</action>
</script>
</cheat>


<cheat desc="Infinite Energy PL1">
<script state="run">
<action>maincpu.pb@818909=40</action>
<action>prot.ppb@4800906c=58</action>
</script>
</cheat>

I'm confused by the two type cheats. It seems that both cheats lead to a identical result. But one is for maincpu, the other is for cpu2.

And When I try to find the second type of cheat in mame debug, I got an error.

When I type:
ci ub,48000000,ffff,2
the system says "no writable bytes found in this area".

Where I do wrong? :(
How to search cheats of this game in the newer mame debug? Now only I can do is search cheats in old mame and transfer cheats from the old mame type.

Please help!
