How to connect my Pop'n Controller to my PC?

[KMasaki]

I need some help trying to get my pop'n controller to work with my PC. Unfortunately, all I have to work with is the Super Dual Box Pro, which is (to my knowledge) pretty outdated for an adapter.

EDIT: Ah, stupid me, I mapped the whole thing in the reverse way, with the buttons not knowing the actions. Any moderator may delete this thread. Thank you!
