Description

Is there an existing issue for this?
  • This is a bug in RetroArch frontend
  • I have searched the existing issues
Description

In recent versions (as I tested, from 1.20.0 ~ 1.22.1) for px68k core, no key is working in x68000 games.
However, in old version such as 1.15.0 I tested, key is normally working in game.

Expected behavior

Please make normal in recent version so that input key is working in game such as 1.22.1 or newer.

Steps to reproduce the bug
  1. In px68k_libretro.dll core, no key in game is not working, which means even if I input any key there would be no action or response in game.
  2. For example, I tested Bosconian. But in other games, there is same issue.

Research direction

Reproduce the missing input in the px68k_libretro.dll core using Bosconian on the reported 1.21.0–1.22.1 versions, then compare behavior with 1.15.0 on Steam Deck or Windows 11. Trace the px68k core's input handling and identify what changed; done means controller or keyboard input produces normal in-game actions in a recent version.
