[Exit any emulator]

After doing a ton of research I found this to be the best script to use. The "~" before the key does the pass-through of the key so you can get rid of the whole last part of your script.

~z::
    duration := 0
    If GetKeyState("z","p")
    {
        start := A_TickCount
        While GetKeyState("z")
            Sleep, 1
        duration := A_TickCount - start
    if (duration > 3000)

    WinClose, ahk_exe {{{StartupEXE}}}

    }
Return

[BigBox: Is it possible to disable or remove these top 2 icons in the alphabet bar]

I don't want any of the kids to accidently click on these and get stuck in a search menu or mess up the games list. Is there an option to disable or remove these? Thanks

lol thanks for the advice.  I'm actually building this mame machine for a friend and was just trying to make it as foolproof as possible. I guess I'll just wait for future updates. Thanks for the info.

starting a MAME game by spamming the start button opens multiple instances of MAME. Can this be blocked so it will only open 1 instance of MAME?
