I bought a used 2018 Xtension Ultimate Edition 4-player with Trackball recently, and can't get even 2-player to work with the free LaunchBox, only 1-player works for any games. Before starting LaunchBox, if I open a Notepad file and start pressing the Xtension buttons, I see the various keyboard characters in the file, so I know all the joystick and buttons are working. I found this 2018 Xtension unit does NOT have the various mode's options of later unit's as I tried holding START and Player 1 top buttons for 10s and nothing changed.
Would you suggest I update its Firmware or would that create other possible problems?
Is there anyway to configure LaunchBox to support more than just 1-player?
Do I need to purchase BigBox in order to support this?
