Dolphinbar Mouse click won't bind as lightgun trigger input #14512

Open ckeisc opened 2 years ago

ckeisc commented 2 years ago

Description

I am using Mayflash Dolphinbar in mode 2 where it simulates a mouse. 1.9.1 is the last version that the mouse click (left and right) from Dolphinbar's simulated mouse can be bound in Input settings AND works in game (say Alien 3 using the FBNeo core). from 1.9.2 onwards, the click can be bound / detected in the Input settings but not working in game. In the latest version (tested in 1.11.1), the click cannot be bound in the Input settings at all. The UI however responds to the mouse click for drag gestures.

Expected behavior

Dolphinbar simulated mouse click should be able to be bound in Input settings and works in game.

Actual behavior

Input settings either would not bind the mouse click from Dolphinbar or it does not work in game

Steps to reproduce the bug

  1. Use a Dolphinbar in mode 2 to use Wii-mote to simulate a mouse
  2. Try to bind Wii-mote trigger as P1 gun trigger
  3. If it can be bound, test in FBNeo with any light gun games with P1 input set to lightgun

Bisect Results

1.9.1 is the last working version, breaks in 1.9.2 until the latest 1.11.1 as of now.

@markwkidd and @MrHuu - you are the lightgun system experts, not sure if you have the hardware to repro this. Mark especially have been the one of the few people making changes to the lightgun code, so hope you have some insights on what might be causing this.
