How can make the controler configuration window show in pcsxr (Ubuntu 20.04)?

I have the same problem previously reported and solved for Ubuntu 18.04 here: PCSXR works fine with one controller, but when the second controller is connected, the plugin window does not open and the controllers dont work. This bug was originally reported and solved (for Ubuntu 18.04) here by Josefien. The solution involves:

• copying the files "cfgDFInput", "libDFInput.so" and "dfinput.glade2" from the PCSXR Ubuntu 16.04 package and copying them into the relevant folders in the Ubuntu 18.04

• install glade

In the last post of the bug report, Josefien mentions that she successfully applied the same process to fix the problem in Ubuntu 20.04 so I was encouraged to try this.

Unfortunately I could not make it work. One of the problems that I had to overcome was finding the files, as the link provided in the post ( https://packages.ubuntu.com/xenial/pcsxr ) does not seem to work anymore and I could not find them either in the file pcsxr_1.9.92-4.debian.tar.gz in https://launchpad.net/ubuntu/+source/pcsxr/1.9.92-4 (although I am aware that I may be looking in the wrong place). To get the files I installed PCSXR on a bootable USB with Xenial on it and get the files from that installation (but I am really dubious that this method will give me the right files).

After using those files as described in the previous post, and installing libglade2-0 this is how my psemu folders look like:

-rw-r--r-- 1 root root 14160 Jul 17  2018 sio1.ui

But the Plugins and Bios Configuration Window looks like this, with the dropdown widget for the Controllers empty.

I would appreciate if anyone could provide any guidance or suggestion. Thank you for your help!
