Bizhawk doesn't use the accuracy core, it uses the compatibility core by default, performance isn't allowed for movie recording. Performance core is an option in the SNES settings (when in non-movie mode)

for emulating a game which is more than 20 years old :\
That's your misconception right there. It isn't emulating a 20 year old game, it is emulating the hardware from which the game runs, via software. The hardware requirements to emulate other hardware requires many orders of magnitude more power than the original hardware. Bsnes is insanely accurate, and that is a tradeoff with speed. However, bsnes is also written with accuracy and code clarity being more important than speed, and has no tradeoffs there. Also, bsnes is written rather insanely where even low hanging fruit for speed optimizations were not taken.
The SNES scene is such that you have poor accuracy or a very slow near perfect emulation written by an insane man (I mean that both positively and negatively).
It is what it is. With Bizhawk, we chose accuracy over speed. But not really. We chose the SNES emulator that comes with a core separated and already made into a .dll, so it was super easy to integrate compared to something like SNES9x. (Very much so actually, had we chosen SNES9x for integration it probably still wouldn't be done). But currently, I find all SNES emulators less than ideal for TASVideos use.
Also, with your machine, I wouldn't use bsnes, it just won't be fast enough. If you were to TAS, I would reluctantly recommend snes9x 1.51 instead. Unfortunately. However, newer CPUs run bsnes significantly faster.

That is exactly right. It is kind of a limited form of judge status, that is basically obsolete now. It was made back when we did a mass unrejection for the tier system.

To be clear, you are requesting the act of emulating unplugging/plugging in a controller, and subsequently recording this act into movies.
Not a UI feature of enabling/disabling controllers (similar to what most emulators have)
This emulation would be on a per core basis, and the movie format would have to be modified in some way to accommodate this. In addition, we will have to restructure the input system to have a concept of what devices are plugged in (a restructuring we will have to do eventually anyway, for things like zapper support).
While I like this idea and would like to see it happen in theory, it is certainly no small task to implement. I am glad we at least have a good test case though, should anyone ever think about taking on the task.

Well I tried to submit the movie but the site won't let me use the submission form.
I'm going to tasvideos.org, log in. Then on the log in page I'm clicking submit movies and then I'm redirected on the step by step instructions page who ask me to log in again.
I tried with both Internet Explorer and Google Chrome but same result ...
Try clearing your cache and cookies, then go tot he home wiki page, and log in. Assuming you have succesfully logged in. Go directly to the submit page

When uppercutting both Honda 2, and Super Macho Man they will raise their guard a few frames before the punch lands. If they successfully do this, the punch will do less damage. Therefore, the trick is to find ways to prevent them from doing this, and thus do max damage with as many uppercuts as possible.
With macho, it is pretty easy to always do this by tapping up at the right time during the punch, it will cause him to raise his guard in response to you pressing up, and dropping it in response to you letting go. With the right timing, you can do this so that he doesn't have time to react to the actual uppercut in time.
The discovery with Honda 2 is that there is actually a timing by which we can do this exact maneuver. Prior to this, the only known way to do max damage was to hit him during his eyebrow shake (which was only a few opportunities during a TAS/Speedrun attempt).

Actually, technically it isn't a new mechanic. It was a known mechanic that is exploited on Super Macho Man, that has been discovered to work on Honda II.
In hindsight, I'm surprised we never at least stumbled upon it by accident many years ago, let alone at least try it.
I'm most surprised that it is such a large improvement as a result. Such a significant improvement hasn't happened in almost 8 years in this game :o Also, you can expect I'll have a submission in the upcoming weeks ^_^

In the case of SNES9x 1.43, pretty much every game is missing lag that should be there. Therefore any run done on 1.51 or later, or bsnes-based emulators will be longer in realtime.
(At least with Super Metroid, aiming for in-game time makes these emulator differences inconsequential)

About the encode, I presume you aren't using any modified rom? 'Cause the sound of some things sounded weird but I hope thats due to the quick encode.
The default setting in Bizhawk is to have the FM Chip enabled (which Dega does not emulate). By turning it off, you can get the sound one would expect from dega.

So I watched this movie and am very impressed!
Optimization is very high quality, including good spread gun optimization (which is often hard to understand and very difficult to optimize). The glitch in level 8 was very surprising. It would be a lot harder to pull off in 2p mode but may be possible to save time on the published movie.
Also, this movie does a great job of being as entertaining as possible. For instance, stage 4 showing off the glitch of falling through the elevator just to show it off, and also playing around with enemies without causing lag (a hard balance to achieve in that level). Getting different weapons in level 8 just to show them off, since he will be dying later in the level anyway, he could do this without costing time.
I'm not usually too fond of slower 1p movies, but this TAS made me a believer. Big yes vote.

Personally I like most the principle "the input should be ended in the earliest possible frame so that the game progresses to the end, and the end of the game cannot be made to happen sooner by providing further input."
Nearly all of my TASes follow this rule. There have been occasions where I've lengthened the completion of the game to shorten the movie, but it was on a scale of mere frames. As for making some kind of rule, I don't think you can, there are several valid opinions there.

Update and try again. That has been fixed. Also, the 4.5 solution file is experimental, I would not recommend using it, unless you know what you are doing and want to worry about fixing compile errors.

1) this is an inappropiate place to talk about the validity of a star movie, we have a thread dedicated to that.
2) Currently there are no rules regarding a published movie changing from Vault to Moon or back. Such a system has merits. The problem I have with it is that I feel like it invalidates the submission voting system. I worry that there will be little point in people contributing with comments/feedback/votes because we can just publish as a vault and see how it goes. Also, I think the rating system is far from accurate and not as informative as a submission thread + votes in gauging the quality of a movie. I'm on the fence about the issue, and as such have chosen inaction for now.

How did you accomplish frame advance? Did you hack the game itself?
I too was looking into how I might tas the PC version of Vice City. I was looking into the extensive hacks/mods of the game to see if I could maybe do rudimentary input recording/playback

What would the ruling be if someone wanted to TAS a super mario world romhack that crashed in bizhawk/lsnes due to a physically impossible echo buffer size that snes9x allows?
I think if the hack depends on poor emulation to work, then I most likely would not be in favor of approving a submission of such.

Well, I guess the stream has run its course. I stopped it (and have my computer back, yay!). Sorry guys.
P.S. I will have that song stuck in my head for the rest of my life.
