For working Dark Injection v8 and SAVE on Steam version! YES SAVE!
To do this, you need to make 2 simple edits to 2 different .txt files in your Spore GA Data folder(Untested on Core Spore)
Open ...SteamApps\common\Spore\DataEP1\Config folder...
Open ConfigManager.txt
Add:
boolProp disableValidation true
on a new line at the bottom of file and save it.
Open Properties.txt
Add:
property disableValidation 0x055d7ca1 bool true
on a new line at the bottom of file and save it.
Launch Spore, Enjoy!
