[TEC] *.exe Reverse-Engineering

[reaper7]

Well I've been trying to delve into this Reverse Engineering - since TDW mentioned ollydbg. Wow its complex stuff.
But I've managed to track down the stadimeter bug - locations in memorry.
I've managed to find the Base Address for the Stadimeter Range, that is the one that is linked to Sh5 memory address on loading and so is available always.
And also both of the Offset routes the stadimeter uses for that value (These use RVA address so change every time on game load - but I have the Base address and offsets).

Now of the 2 routes one is the Correct value and one is the bugged 20M value.

So I can see in the Bugged one.
That SH5 gets the range when using the stadimeter but on mouse release does not change to relflect the mast height - this value is then displayed in the XO Dialogue.

Now the working value.
Sh5 gets the range when using the stadimeter but on mouse release does update the Range to reflect the correct mast height.
(I also noticed that when I click The Stadimeter Fix icon from my Mod it - updates the incorrect value to the correct value - So this 100% confirms my fix is correct, But it would be great to fix the Stock Stadimeter bug in code.)
But the XO Dialogue does not update this value. So the correct value is never used by SH5 just sits in memory - This is most likely SH4 code


Now as my programming skills are very little - I do not know how to redirect the value from the Base Address of the correct value into the pointer of the incorrect value (That SH5 is using).
Don't know how to use Assembly to do the code inject or whatever is nedded to achieve this.


TDW any ideas on how this can be done
I can give you the address for the relevant data, but would like to learn how to do this also - by tutorial or whatever means
