When adding your intro to the compo, please choose "C64 Intro (not crack intro)" as release type. The choice "C64 Crack Intro" is for Intros that actually have been used as crack intros. When and if your "C64 Intro (not crack intro)" has been used in a crack, you can change the release type to "C64 Crack Intro".
I have already corrected the release types for the intros in the compo accordingly. Took a while.
