Summary	03339: phoenix, phoenixa, phoenixb, phoenixc, phoenix3, phoenixt: Ship's firing shot sound is incorrect
Description	To my ear most of the sounds in Phoenix sound correct, except the ship's firing sound. We owned an arcade with several different phoenixes, and I spotted that discrepancy right away (stay around a phoenix for 8 hours a day for months on end and you just know the sounds). But, unsure of myself, I checked the old old phoenix.zip samples file, and sure enough the firing sound is different. To double-check, I went to the local arcade here recently, and played an actual PCB, and surely enough the shots are also different - as I remembered. Finally, here is a YouTube video demonstrating the actual sound from a PCB:
Steps To Reproduce	Simply start the game and play, press fire button. Firing sound is not correct.
Additional Information	To me, it sounds as if the firing sound is actually being played backwards. The actual game makes a "pock, pock, pock" sound. But MAME's sound like "whop, whop, whop". Thus, it sounds almost like it is backwards; or at least the envelope is incorrect. Found this problem in all versions of MAME going back before .78, and at least 4 different ROM dumps.

No.04708 Gyrovision Tester Jul 26, 2009, 05:43	All discrete sound effects were made possible by Derrick Renaud. Before that, the game had really bad sound in MAME. You can see the work he has with Phoenix here: http://derrick.mameworld.info/docs/Tutorial/Phoenix/Phoenix_From_Start_to_End.html The firing sound is not yet finished. There were several errors of component values found in the original sound schematic. I should point out that the explosion sounds of both player and enemy are also incomplete, and in the YouTube video we can compare the sound of the "siren" effect in the 5th stage boss of the first level with that in MAME and find this to be incorrect or inaccurate. One last minor note, in the video, between 6:06 and 6:12 there is a closeup of the Centuri pcb manufacturer sticker which says Amster Electronics Corp, not Amstar. Even though it clearly shows Amstar on the game screen (Centuri sets phoenixa and phoenixb). Must just be an error.
