Description	Right at the beginning of Mission 1, you can shoot the ceiling lights. When you do that, the light should flicker and the room should go dark for a few seconds, then light should flicker again and come back. This effect is completely missing in MAME.

However, when it does so, it leaves the "blend mode" flags set at 0x3000 in line RAM 0xb400, MAME expects the blend mode flags to be either 0x7000 or 0xb000, otherwise it ignores the blending values.
