Hi @karolfilarski, i have same issue and I create temporary workaround, using ESP32-S3 OTG.

What do you need:

ESP32-S3 OTG
Some USB connectors for create powered USB-C to USB-A, or bought it

Process:

Prepare ESP board for OTG using (some boards need solder two pads (in-out + usb-otg)
Install Arduino IDE
Install ESP32 boards
Install library esp32beans/ESP32_USB_Host_HID
Install library ESP32-BLE-Gamepad
Select ESP32S3 Dev Module
Open my code and flash it onto ESP
Pair gamepad with Mac
Connect buzzers via active USB-C to USB-A converter to OTG port
Open terminal in folder with RPCS3
Run this command:export SDL_GAMECONTROLLERCONFIG='0300000002e50000abbb000000000000,BUZZ_BLE_BRIDGE,platform:Windows,a:b15,b:b16,x:b17,y:b18,back:b19,guide:b10,start:b11,leftstick:b12,rightstick:b13,leftshoulder:b14,rightshoulder:b5,dpup:b6,dpdown:b7,dpleft:b8,dpright:b9,-leftx:b0,+leftx:b1,-lefty:b2,+lefty:b3,-rightx:b4,'
In same terminal run this command RPCS3.app/Contents/MacOS/rpcs3
In RPSC3 I/O settings select "Buzz! Emulated Controller" value: 1 controller (1-4 players)
In RPCS3 right click on Buzz game and select "Create custom gamepad configuration"
Select SDL as handler for players 1-4
Clear mapping for this players
Map your buzzers for this buttons (repeat for all 4 users):- R1 = RED
