Hello. In my scenario, certain values residing in certain addresses are being accessed and copied to other addresses.

For example, I have n values residing in n different addresses, and a debugger attached to discover which opcodes are accessing those addresses.

The result is always:

You need to track where the corresponding ECX/CX and EAX/AX registers go, if they go anywhere.
The little code you posted looks like they may be checking if the value is negative.
What they do after the test is for you to track.

Depending on the type of value this is, using Find out what accesses this address should show you where it reads the value (the code you found) and then where it finally writes a value back to the same address.

For example, you would see the mov cx,[eax] that you already found and the next instruction found by CE may be mov [eax],cx.

The game reads the current value, increases or decreases the value, and then write it back to memory.

Or if you found an instruction used for display, the end result may be converting the number into a string and printing it to the screen.
Something you should never need to track.

What are you tracking? What are you expecting? What are you actually seeing?

Do you already have the base pointer for the selected unit?
Are you already using it to show some numerical value about the select unit?
In that same memory region, I expect you will find a pointer address to the unit's name.

So for example, when you find out what access the selected unit's health, you may find:

The issue isn't finding the unit's name (as a string placed at an address I can always identify), I'm having problems with finding the currently selected unit's name which is text displayed in a box.

I think am too low skilled to properly explain what I've got and what I'm actually trying to do. Think I need to learn a bit more before asking for help.

You simply want to be able to find the address of the string containing the currently selected unit's name
When you select a new unit, you want it to automatically find the new unit's name.

You first need to find code that deals with the currently selected unit's base address.

It is much easier to first start by finding a numeric value related to a unit.
Find out what instructions access this address when you select the unit.
That is the code you need to hook so that it updates your name pointer.

By the way, what game is this?
