Yes, saving a copy is vital.
Here are the instructions for editing. Forgive me if I'm stating the obvious.
First, you must use a plain text editor. Notepad will do fine.
find hud.xml in your pokerhands folder.
Open it in notepad.
Search for
game="Five Card Draw">
The first one you fine will look like:
<activestyle game="Five Card Draw">VS 5CD</activestyle>
Search again.
The next one will look like:
<style name="Default" game="Five Card Draw">
It might not day "Default", but whatever it says will be fine.
Now open a second notepad instance.
download this file:
http://www.box.com/s/e478c5e08fbc270ee627
and and open it in the 2nd notepad window.
Press CTRL-A to select all, and copy it.
Paste it immediately ABOVE the "<style name..." line you found.
Save hud.xml
Now, when you open pokerhands, there will be a new entry:
VS 5CD
In your list of HUD configs, and you can edit it as you like.
I tried a couple of ways to paste the actual xml text into this message, but it seemed to mess up the format, and I couldn't be certain that it wasn't messing something else up too.
Enjoy.
