This initially started as a discussion topic here: #1040. The behavior described there is exhibited when using DualShock 4 V2 and Dualsense controllers. The issue that typically presents itself is a random game pause. When playing with my 8bitdo Pro 2 these issues appear to be gone or greatly diminished.

May be related, may not. Discovered that holding Genesis “c” in the game Crying (Bio-Hazard Battle) results in the press and rapid pauses. Checked with different controller types, multi tap compatible and non multi tap dongles. Further testing shows that when the second controller port is disconnected, this game doesn't exhibit this issue.

For reference, the other game I experience phantom presses in is Streets of Rage 2. It doesn't matter if plugged, unplugged, etc. It will eventually exhibit this behavior. Inputs are fast pace as play is at Mania difficulty.

What did you expect to happen?

For the input to be sent accurately and quickly from Sony controllers to the console.

I noticed random infrequent ghost START button inputs while playing. In my case, it happens more often while idling. For example, I pause the game (usually with START button) for a visit to the toilet, to check my mobile or to take a look to a game guide on the tablet, and after a while the pause quits itself when I'm not even touching the controller. This same behavior happened with several games for PS2 and PS1. Notice I updated recently to version "24.04 hw1 playstation" from "1.7.3 psx_external" that came installed when I bought this BlueRetro a couple of years ago, and this behavior described above didn't happen before.

What did you expect to happen?
No ghost inputs.
