I know that a CT is already available but I'm trying to create a trainer on my own. I tried to change the value of my arrows:

1) Changed/Unchanged for byte search. Found and added byte.

2) Find out what writes to this address gives only 1 location:

unepic.exe+93BD8 - 72 2A - jb unepic.exe+93C04

But this location is actually a jump? How is a jump writing to our memory location?

3) So I tried doing a break and trace on this jb instruction and I got only 1 address repeated all the way:

What am I doing wrong here?

Did you also do step 1.5? Confirm that changing the byte has a lasting effect in the game?

Rep movsd copies the memory from one location to another, so it looks like the address you found is for display purpose only

Hi DarkByte, thanks a load for replying to this. You bring up a good point. I was not able to find a value that has a noticeable effect in the game. I basically did the following steps:

1) Scan repeatedly using changed/unchanged

2) Keep firing arrows while scanning

3) Narrowed it down to about a 100 entries. But after that no matter how many times I do they all stay.

Things I Tried to reduce these entries further:

* Try to freeze the numbers a couple at a time => doesn't work the game crashes before I can locate the numbers

*Randomly try to modify some of these values => has no intended effect on the game

* Randomly tried on one of these values => (my first post)

Bump. Could someone please help me?

perhaps something went wrong during your scan ? (you scanned for changed when it didn't change)

Or perhaps it's not stored as a 1 byte ?

e.g: (if it's a 1 bit value shifted along a 2 byte value)
scan 1: 20 00
scan 2: 40 00
scan 3: 80 00
scan 4: 00 01
scan 5: 00 02
scan 6: 00 04

scan 1 to 3 remove byte 2 and scan 4 to 6 remove byte 1 , removing both bytes

I like this idea. So if we search with byte we might miss some important values. Instead I should search for a higher value type. I'll try this out and see what happens. I think it's better to start from the larger value type (like double or float) and work my way downwards if that doesn't work to avoid this problem.

Edit: This problem is solved. Thanks a lot for your help DarkByte!
