SubjectAbout DCS emulation... new Reply to this message

I'm not a programmer or anything of sorts, but I'm just curious. What makes DCS emulation so difficult, or so slow? Is it the type of CPU it uses? Lack of Information on the system? or something different? I'm just curious and would like any Pinmame developer to answer. Thanks.

DCS is 4-channel compressed audio. It's somewhat akin to streaming 4 seperate ~128kbps MP3's simultaneously. DCS on the arcade machines is handled by a DSP chip, but to decompress and playback the streams in an emulator requires some serious CPU time.

The DCS chip is just *very* powerfull, moreso than a lot of CPU's, and the above is spot on, but also bear in mind that it also has to run Visual pinball and Vpinmame as well as the DCS emulation, all of this together makes it a real system eater, especially when lots of things are going on,
