No right mapping for DB9 USB Retro Joystick

[Magisthan]

Hi

I tried to connect Parsec with an old DB9 Joystick from a Commodore 64. I use a adapter which is connected via USB to the PC. The output is a DB9 connection for the Joystick.

The Problem:
when trying to map the Joystick there is a problem for mapping the left/righ axes and the up/down axes. When mapping left/right the (raw) is for both V0+ and for up/down V1-

When I am using a USB Speedlink Joystick the mapping is correct.
up V1+
right V0+
down V1-
left V0-

Is there maybe a solution for this problem? I explained the problem on discord and there was a supposition that it maybe has something to do with HID handling.

kind regards.
