Hyperspin/RocketLauncher Exit Button Delay?

[acjgoblu]

I've been looking all over the place to try to find a way to set the exit/escape button on a delay for my emulators within HyperSpin. I'm planning to have a dedicated exit button for backing out of emulators and going back to previous wheels within HyperSpin, but would like to set that on a 2-3 second delay to prevent accidental button pushes leading to mid-game exits.

I've adjusted the Exit command within RocketLauncher (using Global --> Settings --> Main Settings --> Controls --> Exit Emulator Key) to set it to Esc button with a 3000ms delay, but that's not working when the emulators are open within HyperSpin. I'm wondering if I need to adjust a setting within the specific emulators? I really only care a lot about getting this to work for MAME. Anyone have any thoughts as to how this can be accomplished, or am I just out of luck?
