Robocop uses YM2203, this driver has sound issues.

Taking a closer look, this is similar to 6923, is hard to tell if the sound is playing or if the channel level is too low.

Well I don't think is played too low, really is likely the sound is different or corrupted. I think the sound is the same I've reported in 06166, when batman hits with the attack button.

I'm filling a report about the mame sound engine, maybe with that the developers could fix a issue that will benefit all this machines.

Clearly related to 06740: Setting Overclock CPU: audio cpu to 150% solves the issue.
