Most of the runs posted have been played on a site like Kongregate/ArmorGames. For my latest run (in approval proccess), I switched to downloading the SWF file for the game and playing it directly which allows for more control over resolution (sort of) and makes resetting a bit faster. Would this count as an Emu run or need a new category, or would it be fine as Web?

Also, if it's legal (not my area of expertise), the SWF could be provided as a Resource here.

I believe it would be still allowed, as it would still have been derived from the original. I personally don't see any problems with it, and it would make recording a lot smoother and easier. It would be very helpful if you put the file into the resources.
