(Bug) Space Invaders/Space Invaders M Shooting Sound

Sat Apr 07, 2018 10:05 pm

This was actually noticed by a friend of mine, but if you load up the original Space Invaders (which is marked as working) which uses the mw8080bw.cpp source, the shooting sound seems to be incorrect.

Instead of making a "pew" noise, it sort of goes "peeeeee"

I know I sound like I'm rambling, so here's a video my friend did showcasing the problem and that it used to work on a very old version of MAME. He used 0.175 in the video to show the error, however I can confirm it is still a problem in 0.196

Hope you guys can fix it :)

Thanks!

There is a long term issue with invaders sound

No idea on timeframe for fix because discrete is a specialized emulation skill that few people have.
You or your friend may have to use an older MAME version with hardcoded samples (which all invader sets used prior to MAME 0.114u2 used).

OK, didn't realise it was already there, my apologies.

Thanks for the reply :)
