Since most people actually prefer to play with NES controllers on their Famicom I decided to do the opposite since I want to connect my Hudson Joycard to my PAL NES. While doing so I used the schematic in the attachment.
Colors only indicate cables of current wires.
I've connected them all together.
Checked every connection with a multimeter multiple times. Even with the Hudson Joypad plugged in (from DB15 to NES Controller 1). Everything is wired correct but it's not working. I tested NES and Famicom games but it looks like something get triggered automatically since it does something but no input works.
Also, the controller was tested on my Famicom with the same game and it works.
Game is Battle City.
Anyone have an idea to what could be wrong?

EDIT2: Solved, the problem were 2x 3.6k pull up resistors used in PAL NES controllers. I added them to my adapter and it's working great now.
