Summary	08906: gradiusb: The voices "Presented by Konami", "Getting Ready" and the countdown voices doesn't play at the beginning.
Description	I never knew about this until a friend of mine in Discord sent me a video of the startup sequence from Gradius (Bubble System) recorded from the PCB, in the video, the 3 mentioned voices plays before the music plays and prepares for the "Warming Up Now" countdown. In MAME, i don't know if this is because of the defined CPU power but seems like there's no room for those voices to play, ecept if you pause at the very first frame when the game starts, underclock the CPU to 50% (I will asume less than that wont work) then unpause the game, you will only hear the "Presented by Konami" voice.
