So I have completed the tutorial successfully (both x86 and x64 versions), and I got bored and did it again today (only on the x64 version). (edit: I suppose I should probably mention that I'm using ce ver 6.3 and win 7 x64...)

Last time I did step six I just got the pointer and froze it at 5000 (I saved the table I used, that's the only reason I know), this time I tried to use an assembler script to set the new value to 5000 after pressing change pointer (so that it's basically just enable script and press to continue) and I found that it didn't work...at least not when pressing change pointer, however it does when pressing change value. So I tested simply freezing the pointer and pressing change value, and that fails to work.

so I'm curious if anyone can explain why the script works when pressing change value but not when freezing the value (I assume that the change pointer button doesn't use the same code to change the value as the change value button does and so fails there, but that doesn't explain why the script magically works with the change value button).

here's the script I used btw:

Because different instructions are being used to alter the value and alter the pointer address. You can use injection, pointers or a combination of both to defeat this step. If you freeze a pointer address value to 5000, you can defeat this step by pressing 'change pointer button'. If you inject code at an instruction that handles the values for 'change value button', you can defeat this step by writing a script that always sets the value for those addresses to 5000. You can also inject at an instruction that accesses the pointer for your pointer address. Here, you can generate the value of the pointer address within the script and alter it by locking it at 5000, similarly to freezing the pointer address value, but by using injection. By doing this, pressing the 'change pointer button' will defeat this step.

Anyway, this step was designed to teach you about pointers. As long as you use pointers or circumvent them altogether by using injection, you can defeat this step. The method that you use is up to you. Also, it's just the way the tutorial was written.

Simply put, when you press button1 (change value), the value of address1 gets changed by instruction1...but when you press button2 (change pointer), address1 changes to address2 by instruction2 and instruction1 doesn't get accessed again until button1 gets pressed. As you can see, different instructions are being accessed when you press button1 and button2.
