I have just watched it. I wanted to vote yes, but unfornatuly I am voting no for three reasons : - You don't get all the emarald, so you get the bad ending. - You have use a zipping mechanic in the last battle. I was so pissed that I closed the emulator... This is the reason that demote my vote from a weak yes to a strong no. So my vote is a strong no. I will vote yes for a true "no zipping, true ending" run of sonic 1 This is a little sad because the run is pretty well made, but It is my opinion... so sorry.

1. I don't use zipping in the Final Zone, it's sprite ejection as explained in the submission text.

Seems kinda similiar in my opinion. =/ To be exact, isn't zipping just the game trying to eject you out of the game's terrian? So even though your trick might not give a large speed boost, it still (sorta) counts as "zipping". =p

I noticed there was a pause for a few frames in the Final Zone before entering the battle, was that to manipulate the boss position perhaps?

I do not like this run because it does "zip." Reading this artice: http://tasvideos.org/GameResources/Genesis/SonicTheHedgehog.html

From reading the above posts, my impression is that this run simply refrains from using a particular glitch that - to an untrained eye - resembles another glitch that IS still exploited. I haven't watched it yet, but I think my vote will really depend on whether I, a TAS layperson, would agree with Derakon that the omitted glitch substantially changes the run.

When you remove one game-breaking glitch only to make use of another, it seems pointless.

At worst, it's zipping, at best, your too arbitrary with this run since you can do Sprite Ejection, but not Terrain Ejection. Then things are clear.

Something which might seem similar to zipping and is allowed is terrain-ejection and sprite-ejection

How about a no glitch run?

To be clear, sprite ejection is not a glitch. It's a fundamental mechanic of discrete (i.e. non-continuous) physics systems, which basically all games use. You can't detect a collision between two objects before those two objects are actually intersecting; at that point, you have to decide how to fix things so that the objects no longer intersect. Typically this involves backing out one or both of the objects -- sprite ejection -- though plenty of games simply destroy the offending object (c.f. most scrolling shmups). Depending on how many resources you can dedicate to the task (and how skilled of a programmer you are), collision response can be more or less accurate, but in any case it's not a glitch. Zipping is the game going "oh crap, my usual routines for fixing object intersection aren't working." Sprite ejection is perfectly normal and expected behavior whenever two objects bump into each other. That's why they're qualitatively different.

I can just inform you that given how this game works, a run strictly without ejection can't be made at all, since that would require that you not only must hit each wall with a speed of less than a pixel per frame, but also land every jump with a y-speed off less than a pixel per frame (which even if it was possible would made for an extremelly stupid looking run). And thus I allow all ejection no matter how small or big. Or maybe you think the goal would've been less arbitrary if I had set an unmotivated upper bound of how many pixels I can be skifted?

Normal Sprite Ejection (killing enemies) is perfectly acceptable since the programmers intended this, but glitching in Scrap Brain 3, was NOT their intent. My vote stands due to this.

Aglar,

Normal Sprite Ejection (killing enemies) is perfectly acceptable since the programmers intended this, but glitching in Scrap Brain 3, was NOT their intent. My vote stands due to this.

Your submission text says, "By setting up a goal like this it pretty much forces you to actually play the game like the programmers intended" But, your Sprite Ejection on Scrap Brain 3 is NOT what SEGA/Sonic Team intended for the game. If they did, then why go through the effort to make that level? That's why I stand by my vote.

"By setting up a goal like this it pretty much forces you to actually play the game like the programmers intended" By this I meant "normal game-play almost everywhere"
