So I started making some mods for Battlescribe Catalogues
You can download Battlescribe here
http://www.battlescribe.net/downloads.html
In order to use you're standard codecs, you need to go to this website and download the file listed under the link "Warhammer 40,000"
http://battlescribedata.appspot.com/#/repos
It should download into your download folder [C:\Users\[Your Profiles Name]\Downloads as index.bsi
Then you run Battlescribe, and it will prompt you with the "Getting Started Window"
Click on the button labeled "Add a repository"
Click on the button labeled "Import Data From a File"
Select the index.bsi file and click "open"
Congrats, you can now use Battlescribe to build your lists!
You can download my
CUSTOM Codecs here:
Ork Codex (Very Similar to Space Odins Codex)
Chaos Marine Codex (Cheaper & More Balanced)
Space Marine Codex (Lots of little tweaks here and there)
Eldar Codex (Nerfs to D weapons, increased point cost to wraithgaurd and wraithknight, tweak to Windriders)

In order to use them all you have to do is download the file derpa.bsr, open the roster editor, click under file, and click import data file, then find the file you downloaded and select it. When you open a new roster, select you're detachment (Usually Combined Arms Detachment or Formation Detachment) and select the catalogue from the catalogue tab, (for example "BS40k_Chaos_Space_Marines") from the tab. All the new changes and rule updates should be there!
Let me know if you have any problems let me know and I'll be sure to help you out!
