Is it possible for you to give me some clues to the source code of keyboard event listener? I might be able to make a little contribution.

Thanks for your willingness to contribute! However, this seems to be an upstream problem that we cannot put any effort into.

The browser keyboard events are handled by RetroArch directly, without being modified by Nostalgist.js. I guess the reason you are encountering this issue is that you are using an IME, and sometimes that can lead to the event.code being modified, while the event.code is used internally by RetroArch.

You can check if you are receiving the expected event.code at keycode.info.

To work around this, you can try to turn off your IME or use another key as the key mapping for the select button. Let's say the quote key ' is being chosen:

await Nostalgist.launch({
  core: 'fceumm',
  rom: 'your-game.nes',
  retroarchConfig: {
    input_player1_select: 'quote',
  },
})
