So I have viewed some old threads of this particular question recently, however it does not seem to solve the current problem I am looking for.
What I am looking for is the location for the "default" chrome themes.
In %appdata%/Local/Google/Chrome/Extensions one is able to search something such as "theme_ntp" in this folder and it will show the results of the background image for downloaded themes (Not the "default" theme).
It appears default themes are not stored here, anybody have a clue where it is? I should mention, my goal is to change the background to a custom image (something.png) over the theme, which doesn't work when you have a theme installed.
