AFAIK MAME's accuracy leaves a lot to be desired with respect to anything involving analog signal paths. For example, the sound system used in the Sente SAC-1 hardware is based on the CEM3394 chip, also seen in several pro synths of the era. The emulation does play sound, but last I checked, there wasn't any filter emulation, so it poorly represents the audio of those games. Edit: And I wouldn't expect the situation to change soon. Accurate analog emulation is something commercial VST plugin makers have been working on for years, and they've come "close enough for most people", but the time spent on algorithm development and optimizing CPU usage is quite high.
