To use this script, you'll need to download Cheat Engine 6.5, and unzip the DaSCompilation.zip file. After launching Dark Souls, load a character, open Cheat Engine and load DaSCompilation.ct. Attach CE to DARKSOULS.exe, then enable the script.

If you've never used Cheat Engine before, it's very simple.
To load a script, click File in the upper left corner, then select "load" and use the window to select the script.
To attach CE to a process, again click File, then "open process" and use the window to select the process.
You can also use the buttons directly below File, with the computer button representing "open process", and the folder button representing "load".

This table is only updated for the current release patch of Dark Souls, and only works in Cheat Engine 6.5. If you're experiencing any issues on Windows 10, I apologize, but it seems to be a recurring problem that Windows 10 works incorrectly with some Cheat Engine scripts. You might be able to use it by running Cheat Engine in compatibility mode as an Admin.

If you're experiencing problems otherwise please make sure first that:
You're using the current patch of DaS
You're using Cheat Engine 6.5
Cheat Engine is attached to DARKSOULS.exe

If all that is true, please do leave a bug report.
