Old OP, for archival and/or those who don't have the Patch:
To install it, you need to make 2 simple edits to 2 different .txt files in your Spore GA Data folder(Untested on Core Spore)...
Open ..Electronic Arts\SPORE_EP1\Data\Config folder...
Add boolProp disableValidation true on a new line at the bottom of file and save it.
Add property disableValidation 0x055d7ca1 bool true on a new line at the bottom of file and save it.
Launch Spore, Enjoy!
This mod removed the save block on my game without any mods. I just launched the editor, and hit save, which saved a spine fine.
This tweak also works on Origin and Retail Spore. Untested on GoG Spore, but it probably works there too.
