Description

Hitting the frame advance key while recording input tends to result in the game unpausing, without sound.

  1. Start recording input.
  2. Pause emulation and begin to advance frames.
  3. After a few frame advances, emulation should unpause by itself.

4.0-6820 tested. Can't test any more right now, since the website is down.

I don't run into this issue myself, was testing it the other day.

I tried it again, and apparently it only happens when pausing the game using the Frame Advance key, a massive habit of mine.

  1. Start recording input
  2. Press Frame Advance to pause emulation
  3. After a few frame advances, emulation should unpause by itself.

Seems to happen with all revisions tested. If anything, Frame Advance shouldn't work unless emulation is initially paused.

This is a regression from 4.0-5402, when the hotkey functionality changed Wrong.

to further comment on this, pressing play and pause repeatedly will also trigger the issue.

Fog, do you want to own this?

This seems to be more an issue with how the GUI interacts with the CPU core than just a single frame advance issue. Possibly a race condition?

Nevertheless, I think the title is misleading because frame advance is probably not the only place this issue occurs, but it's the most obvious place to find these issues.

@delroth: This issue is probably better suited for someone with much more intricate knowledge of the GUI and CPU emulation.

This isn't as much of a blocker in comparison to the rest of the blockers, I'd be okay with having it removed from Current milestone.

It's a regression which makes TASing really annoying.

Easiest way to reproduce this is to load a fifolog and attempt to pause it. Holy shit is it annoying.

The Urgent priority is for breaking something everyone uses, not FIFO logs and TASing.

FIFO logs issue is separate from this issue, and it has a PR in place to fix it.

As for this issue, I have nothing.

No wonder I had nothing, 4.0-5402 was not the reason this broke.

The real regression happened with 4.0-6364.

The changes in 6364 have been reverted in PR 3712: https://github.com/dolphin-emu/dolphin/pull/3712

That PR was completely incorrect in the way of fixing the issue, going to work on a better solution.

I'm trying to understand what happens here. To me it looks way to obvious:
"Press Frame Advance to pause emulation"
and then press the same button to continue? So Dolphin executes the hotkey 2 times in a row, even if it's just pressed once? That doesn't sound like a race condition with pause/unpause, but an issue with hotkey handling.

Also, mimimi, that's not how frame advance works. If Dolphin is paused, pressing frame advance is supposed to unpause only for a frame, not permanently.

Dropping from Current. Current fix is a huge change before a 5.0 release. I'll be directing TASers away from stable so they don't run into this issue.
