1. As Masterjun said before‚ getting the cloud doesn't require ACE (looks like some people didn't get it‚ I can understand that it's not obvious). So you can get the cloud and not use ACE‚ because avoiding ACE is one of the aims of the "warps" category.

The glitch always jumps to open bus. The reason why the game can continue is just because it managed to get back to the normal code again, but the fact that it executed open bus makes it not different from the ACE run.
So you could say: "If you get the cloud you might as well get directly to the credits."
Maybe don't misquote Masterjun in the future ;)
If it helps to think about it this way:
Real time runs that use the clouds are actually attempts at the 'arbitrary code execution' category, except the most they can do with it is get the cloud because they're weak meatbags that can't jump to the credits in real time.
So we already have a TAS that's the same category as this route - it's the 44 second TAS Masterjun already submitted!
Oh, this is actually the sequel to 'Another Perspective'. I was hoping for a TAS of Perspective ( that's this game: https://www.youtube.com/watch?v=OSy9_g6G9P8 ) and got excited XD
The third level in your testrun looks slow (if you jump to the key earlier you won't lose frames waiting to fall on it before being able to turn around), but I guess you knew already.
Thanks, I'll have a look during the weekend and see if I can find something wrong here.
OK. You can look at the source code for the game too, if it helps. (If you discover anything, it will probably be something common to all SDL using games, since it just uses SDL + SDL_image for graphics things and rand() for randomness.)
Edit: Lol, looking through the sourcecode, it looks like it has a commented out replay scheme - open levelblit.c and ctrl+f RECORDING and PLAYBACK. Wouldn't be good enough for TASing without re-recording, but neat.
Just to make sure - if I can get a game to work in Hourglass, and it plays back the same input with the same timing every time, but some other aspect of it is random (like monster AI) and is different every time, and it looks like the game needs multithreading to function (if you disable it you can't run it at all in Hourglass), are there any kinds of 'tricks' I can try to see if I can get it to playback deterministically entirely, or are such games out of reach of Hourglass for the time being?
(If you are curious, the game is http://asceai.nfshost.com/meritous/ . Plays back on Windows 7 with Multithreading Mode > Allow or Wrap. It crashes about 80% of the time, keep trying until it loads in Hourglass)
EDIT: Oh! I just noticed the game page has the sourcecode uploaded - http://www.asceai.net/files/meritous_v12_src.tar.bz2 - so that will help :)
EDIT 2: ctrl+shift+f thread has 0 results, ctrl+shift+f SDL has 320 results. Does SDL do some magic that transforms a threaded looking program into a multithreaded one?
My city (Lugansk, Ukraine) is going to be subjected to bombardment next week! I must run away from the city anyway, so I won't have internet connection! If I need to edit my movie, delay my submission, please!
Getting cloud itself is not ACE (at least it doesn't have to be used, or well this is what causes redundancy if it is used).
As masterjun says, getting the cloud is ACE, just that real time runners can't exploit it:

(Similarly, real time runners of Megaman [NES] can try to use the crazy, level skipping glitches that are used in Megaman TASes, and even if they get ones that are technically ACE, they can't do ACE applications of it because they don't have superhuman control over the input - and you could ask 'make a Megaman TAS that uses the RTA route instead of ACE' and be answered with 'well, when you do the glitch in RTA you have ACE anyway, so may as well use it')
I thought dual(2games) run with 2player. Dual run is easier to make than single optimized run or quad run, so I thougt 2 games with 2 player. However, I couldn't come up with games. So I have never tried it.
Mario Bros (the one where you hit enemies from below to stun them) and Snow Bros?
Two different Arcade Bubble Bobbles? (Arcade opens up a lot more possibilities because they basically all have two player modes)
The current warps run already uses incredibly sketchy memory corruption to skip at least one stage. This more or less follows the problems that surrounded the recent Mega Man TAS, that it's basically a less efficient version of the "game end glitch" one.
You can't get ACE with the orb glitch, is the difference.
The glitch always jumps to open bus. The reason why the game can continue is just because it managed to get back to the normal code again, but the fact that it executed open bus makes it not different from the ACE run.
So you could say: "If you get the cloud you might as well get directly to the credits."
Makes sense. It's like if you did memory corruption in yellow then decided not to jump straight to the end of the game.
I believe the flower in the ET game is just a one-up item; it is not something that is required for "100% completion". Therefore I don't feel that "flower%" counts as a distinct branch for this game.
I showed the encode to TAS first-timers, and they wouldn't believe me when I told them the input was the same. Are the 4 videos sync'd ? Would it be possible to display the input on the Youtube encode ?
Yes.
Aside from obvious things like 'jump only makes some jump if others are in the air', the behaviour of L+R and U+D differs between versions, allowing for the same input to move different games in different directions in a limited way.
The big update finally came out:
http://distractionware.com/blog/2014/06/outer-space/
1) VVVVVV on Steam is now 2.2.
2) iOS, Android and Ouya ports of VVVVVV are now live.
3) The level editor for VVVVVV is now a free stand-alone program.
^makes me wonder why nobody tried to do that sooner
Hindsight is 20/20 my friend. Every glitch/trick looks obvious once it's found :)
uhm… I don’t think so… all of the crazy cloning glitches pannenkoek has uploaded actually do look impressive, a jumpkick from a previously already known OoB area isn’t
