Description

@juanmurillo04

System:

Windows 11
Xbox Riffmaster
RB4InstrumentMapper v5.3.0
GHWT Definitive Edition

What works:

  • The guitar connects to the PC and works in Fortnite.
  • RB4InstrumentMapper detects the guitar through GameInput.
  • In the mapper, live packet data changes when I press frets and strum.
  • vJoy is detected and the mapper says it created GuitarvJoyMapper.
  • The same vJoy mapper creation behavior repeats across restarts/tests.

What does not work:

  • In ViGEmBus mode, input seemed to stop when RB4InstrumentMapper was not the focused window.
  • In vJoy mode, joy.cpl shows no button activity at all.
  • GHWT Definitive Edition sees the device but cannot bind/use any inputs.
  • PacketLogs is not being created even with both Show packets and
  • Log packets to file enabled.

What I tried:

  • Rebooted the PC
  • Re-paired/reconnected the guitar
  • Tried both ViGEmBus and vJoy
  • Ran RB4InstrumentMapper as administrator
  • Verified vJoy was configured
  • Tested in joy.cpl
  • Confirmed the guitar itself works in Fortnite
