Well, the "official" thing has to do with how I worded the question in the poll. Emulation eeked out a pretty thin win, and I don't want to piss people off that voted with some specific expectation.
I guess we'll call it a "pool" of official emulators that you can choose from, that will only include "accurate" emulators.
So "official" emulators:
Nintendulator
FCE Ultra
Nestopia
If your system can play some variant of those, you're golden.
On the light gun/peripheral topic...from the standpoint of participation, I really don't think we should do any game that requires the light gun this year. People who don't have a CRT would have to emulate...and at that point they might as well be playing a different game, due to the differences in input methods.
There is a deep enough library of non-zapper games that there is really no need to pick from them (and we played the only "good" ones last year anyway )
