Game pauses when I try to save state [SOLVED]

[T-Prime]

Using arcade buttons connected through an IPAC2 in keyboard mode. All the buttons do what they're supposed to, and most of the hot keys work. The only exception is that when I try to save state (Hotkey+R (arcade R, not keyboard R)) it pauses. The R button for Player 1 is mapped to "k" on the keyboard. If I press the button a second time, it does save rather than unpause. I have to use Hotkey+X to open and then close the RetroArch menu in order to continue.

Happens on all the emulators I've tried.

k is bound to 'frame advance' in RetroArch by default. You should unbind this function in your configuration

input_frame_advance = "null"

or use another key for the save state.

@mitu I tried removing it. I'll try explicitly setting it to "nul" and see what happens. Thanks.

Edit: Yeah, that did the trick.
