You can't change history. Even before 1990 I was starting intro code with jsr e544, inc d019, inc d01a, inc dc0d and using jsr ab1e to print the intro credit. Also intro by psycho! has in explicable spaces in the string, whereas in my intro it fits perfect with the intro credit.

probably copied from Insane (US) 01

Allthough I never liked this kind of style in intros I'd say this one's allright.
