I'm pretty confident that the Flare Gun effect is not emulated correctly in any known video plugin. On the real system, I seem to recall it actually lighting up the surrounding area, whereas in each plugin I've tried, it only creates the ball of light itself and does not affect the surrounding lighting at all.
Its not easy to find a screenshot or video of this on the web, as most people seem to be using PJ64 to show the weapons rather than the real system.
Attached is how it currently looks with Jabo's plugin, and Glide64 and 1964video look the same.
