We've tried changing the memory split from the default 256/256. We've tried overclocking to the Modest and Turbo settings (and also no overclocking of course) but neither made a different in the lag. This may indicate that it's not an emulator issue. We've tried using both the default RetroArch SNES emulator and pisnes (the one included in the RetroPie SD image) but they both have the same lag.
DELAY ON MAC NINTENDO EMULATOR PC
When I play the ROMs on my PC (the exact same ROM files and ZSNES) there is no lag at all using a controller or keyboard. The lag seems a little less on Metroid but that may just be perception, it's hard to tell with those time scales.

We've primarily been testing using Super Mario World and Super Metroid ROMs. The same lag is experienced using a controller (wired Xbox controller) or a keyboard but to ensure that it's not a controller issue we unplugged everything except the power, HDMI, and keyboard and ran tests using a keyboard. We are using a power supply rated for 1.8A so I don't think it's a power issue Here is everything we have tried and other relevant information: Scouring the forums, we've tried a multitude of things to reduce the lag but nothing has worked. It seems great but we are getting about 200ms of lag between the controller or keyboard and the action on screen with the SNES emulators.
