Finished enough of ImportFMV for now.
-There's "FDS data" stored in the frames of FDS recording. I have no idea how to handle this. If we do in fact support these features, they should be utilized in the TODO section provided. -99M syncs with this...isn't this a problem? Wouldn't this imply that bizhawk is as inaccurate as Famtasia? I'm pretty sure this run didn't sync when I tried it on my now broken NESBot. TODO: I guess I'll try to move on to ImportFCM now. Although I heard this is a difficult format to work with, my favorite console is the NES, and this'd be useful for console verification if the NESBot Lua script gets adapted for bizhawk, so I think I'll give it a shot.
