Issues with zero delay joystick

[fhdelrio]

Hi, I am using two zero delay boards for my arcade and everything seems to be working fine, but there is an weird issue.

The joysticks work fine in the following directions:
UP
DOWN
LEFT
RIGHT
UP+LEFT
DOWN+RIGHT

But it doesn't work in the following directions:
UP+RIGHT
DOWN+LEFT

This is really anoying: Playing Metal Slug (MAME), if I am walking to the right direction and then aim up, the character stops walking. I thought it was some problem related to the game or the MAME emulator, but the same problem is happening for every other game and emulator (for instance: I tried Earthbound, a SNES game and the character could walk UP+LEFT and DOWN+RIGHT, but it couldn't walk UP+RIGHT nor DOWN+LEFT). This is only happening for both zero delay arcade controllers, this doesn't occur using a Xbox 360 controller.

Did someone got the same problem?

Pi model: Raspberry 3
Retropie version: 4.0.2
Built From: Pre made SD Image on RetroPie website
USB Devices connected: Only the controllers

Thanks

Hi guys, I just figure out what was wrong. I noticed that the zero delay joystick directionals should be connected in a specific order in the board: UP | DOWN | RIGHT | LEFT and I connected something like UP | RIGHT | LEFT | DOWN.

I thought the position wouldn't matter because I could set them in the retropie. Probably the board can't handle UP+DOWN and LEFT+RIGHT simultaneously, what makes sense, but when I connected in the wrong positions it wasn't handling UP+RIGHT and DOWN+LEFT simultaneously.

Anyway, my problem is solved now,

Thank you
