Can I watch dev ghosts I've beaten?

Once you get close enough to the rainbow flower time, you get to see a dev ghost performing the dev time as you play. Once you beat the rainbow flower time, the dev ghost stops appearing. This can be annoying if you want to watch the ghosts again, or if you beat a dev time without ever seeing the dev ghost.

Is there any way to get the dev ghosts back, besides wiping your save or something?

Solution 1:

It turns out, if you get 100%, you unlock a button to turn all dev ghosts back on. I'm not sure whether the requirement is actually 100%, or slightly easier; I unlocked the button when I hit 100%, but I got the last rainbow flower on my first clear of the last level, so it might unlock when you get all blue flowers or all gold flowers or something.
