Summary	04061: quasar: Missing sound effects
Description	The boot/start sound and the alien shoot sound is missing in Quasar since MAME 0.127u1. Source: drivers\quasar.c was changed and i think it has something todo with a missing soundlatch clear (see snapshot).
Steps To Reproduce	Start MAME 0.127 with Quasar and you can hear the start sound. Then compare it with MAME 0.127u1.

So maybe that soundlatch write should be there and was wrongly removed. EDIT: here it is: // not necessarily like this, but it seems to work better than direct mapping // (although schematics has it as direct - but then the schematics are wrong elsewhere to!) Also this note at the top of the driver: - Sound (missing invader effect - still not sure all noise in correct places)
