I'm trying to follow a guide to give me infinite energy in castlevania 3.


It says to do this.
Search for A5 aa ?? ?? ?? 85 aa.

Then change the 85 to A5 for infinite amount.
First, I did the mem write for $003C which shows
$828A 85 $sta 3C = 38
It says to change those values, but doesn't say how.
I also have a program called "gamegenie code converter" so I can convert the data to give me a gamegenie code.
I can easily find addresses and cheat that way but I also want to learn how to make a gamegenie code.
I get some of those symbols but what I haven't been able to do is to test anything.
