It's been suggested in IRC that one possible way to avoid desynchs is not necessarily stronger software that can handle desynchy games, but in knowing when a frame is dropped, which seems to be the case for why N64 games desynch. (This has been shown to happen in both Exp Pak and non-Exp Pak games.) This would be a good, early solution before a better emulator was made to handle fragile games. If there was some way to detect when a frame is dropped during recording, and possibly a visual alert was made saying "Frame #12728 was dropped" in bright red letters or something, that might help a TASer in knowing immediately if a desynch occurs, rather than have to play back the entire movie in read only mode and discover that a larger portion of work has been made useless due to a desynch earlier on. an alert during recording would mean that you'd instantly know if a frame was dropped, you would still have a savestate before then, and already know the frame where it occured, so you can immediately proceed with caution. This would save a lot of time and effort on the TASers part. Could a feature built into mupen, or an external reading program (like Gocha's external mem watcher) be used to monitor dropped frames?

Thats a possible soloution but it wouldn't be the silver bullet in relation to solving N64 desyncing issues.

Yeah, it would be more of a silver bullet fired at a broken leg, just to remind the user of its misery a few times per second.

silver bullet it isn't, but it would be a much better way. knowing a desynch just occurred during recording is much more helpful than you might think. As Mukki will tell you, he'll do some progress, maybe a minute's worth, usually less, then have to play back the long movie in 1000% speed, and check for desynchs. This obviously wouldn't be a permanent solution, but a very helpful one to have, especially since likely you'll be doing frame advance, and you'll be right on the spot, during recording, of where the dropped frame is and can immediately fix it without having to replay the movie and lose any progress. can such a program be made or feature installed?
