Summary	01059: brubber: Low pass filtering on engine and explosion sounds is not emulated in MAME.
Description	Here's a recording from my Burnin' Rubber PCB. Notice the low pass filtering on the engine and explosion sounds. Towards the end of the recording some percussion sounds join in - these are unfiltered. Here's a random picture of the amp circuit. I'll be happy to provide any details, just ask.
