fix: keyboard input (#83)

[sonht0555]

Recently I saw that you have to downgrade to handle the problem of input (not allowing continuous deletion, input input is very slow) I solved it by [ remove keypress-keydown-keyup in _emscripten_set_keydown_callback_on_thread in mgba.js file ] I think there's no need to downgrade.

That js file gets compiled based on my fork located here, which is compiled with emcc. So I don't manually modify the generated output file.

I do like the keyboard for desktop support, and usually it plays nice with me stopping keyboard events when modals are open:

See here for how I do this today.

Upgrading to the latest emcc caused this not to work, which I believe is a bug.

Downgrading the emscripten compiler (emcc) solved the issue by fixing the disabling of events in my case. I assume it will be fixed eventually in the emscripten/core repo soon.

What did you see in reference to slow inputs?

I've never experienced that.

I do know continuous deletion in form inputs works just fine.

I was wrong, the input still works normally, only when deleting, it cannot be deleted continuously, and is interrupted. The problem is that the keydown events on mgba.js have an impact

Do you have a video of what your seeing?

From what I can see, continuous deletion is functional:
