DDP DFK 1.5 Strong style won't unlock

[Link_Z]

Hi, I was just messing around with my new DFK 1.5 PCB and noticed Strong style isn't unlocked by default.
I've just followed what I found here: shmups wiki

But after a 1-ALL run with bomb style, strong style is still locked. I cannot easily enter the code now so I'd rather use the 1cc way.
Is the wiki wrong?
Thanks in advance.

Shmups wiki is erroneous here. You cannot unlock it with a 1CC. Only the code works.

Alright, thank you EOJ.
