Okay, I can't tell you exactly which is the best combination as there really isn't one. Firstly, grab the latest version of 1964.
-Either use Jabo's DirectX6 1.5.1, Rice's Video Plugin v6.0.0 or Glide64 0.7 ME SP8 as your main video plugin (recommended - Glide64 0.7 ME SP8, use either with glide wrapper that comes with plugin, or get amazing wrapper from http://www.zeckensack.de/glide/archive/GlideWrapper082b.exe ; next best is Rice's Video Plugin v6.0.0)
-Use either Jabo's DirectSound 1.5 or Azimers HLE Audio 0.55.1 Alpha plugin for sound (Use Azimers HLE Audio 0.55.1 plugin).
-The best pad plugin to use is N-Rages Direct-Input8V2 1.83 plugin.
Test those and see how it goes.
