I am pretty certain it has nothing to do with the number of sprites. In the Mandrill heart video, there is literally nothing on screen except one boomerang and one health drop. It really just scrolling an item on screen right when you steal a boomerang's item I think. What exactly causes it is still mostly unknown, but I'm pretty sure sprite count doesn't matter.

My guess is that it is something to do with how the game handles powerups and then also a flawed flag for the boomerang. Something along the lines of after you grab the powerup that the boomerang is holding, it does checks after to see if the item still exists before deactivating the flag. Past Capcom games have used an indexable stack sort of setup for keeping track of enemies and things, so it wouldn't surprise me if they used the same thing here. So when you grab the item with the boomerang, it pops it off the stack. However, that same frame you move another object on-screen, which gets pushed on to the stack. The boomerang still has an active flag for thinking that it's holding something with a reference to that particular index (probably some other checks occur too), so now the new thing that appears is instead considered grabbed by the boomerang and has its position updated to match the boomerang. Again, I have not played around with the bug nor looked into it at all, so this is just speculation.

That's basically correct (except that it is not called a stack). If the boomerang grabs a powerup, and the powerup disappears (for example, by taking it without touching the boomerang), and another powerup is then loaded into the same index on the same frame, the boomerang will be none the wiser and will continue to hold the new powerup.

Whatever it's called aside, the structure I'm referring to is a list where newest items appear at the lowest index and all other items are moved to higher indices. There's a number of ways that this can be done (including in the opposite direction) but for Capcom at least I've seen lowest index for newest elements as the convention.

To put it short, could phantom grab be used to bypass the Dash Boots somehow? I have no idea how the mechanics for that glitch work, but at least there's some woodchipper dudes who fling platforms at you in that level, so, maybe it'd be somehow possible to phantom grab one of those and get by somehow without the boots? Another possible way would be somehow getting the buster upgrade without the boots, since charged Sting and Shield allow you to pass through the container freely. I dunno how you'd get the buster, but yea. The reason why this'd be very neat, in my opinion, is cause I feel a TAS without the boots would sort of feel like an extension of the classic series. Don't get me wrong, the MMX TASes look amazing, and I wouldn't wanna substitute any of them for a slower paced TAS like this, I just think this might make for a fresh new take on Mega Man X and how it's played. So uhh, if you got any info about possibly skipping Dash Boots, in any way, lemme know.

why another thread..sorry for replying and givin u a hope for answers
I want all good TAS inside TASvideos, it's my motto. TAS i'm interested: Megaman series, specially the RPGs! Where is the mmbn1 all chips TAS we deserve? Where is the Command Mission TAS? i'm slowly moving away from TASing fighting games for speed, maybe it's time to start finding some entertainment value in TASing.

I wasn't sure where to put it, so I put it here. Now that you mentioned it, it's totally my bad for not searching for a low% topic before I posted... Sorry about that. EDIT: Actually, apparently there's no low% topic (at least none that I could find), but there is a general Mega Man X topic, which would certainly have sufficed for a question. So, sorry again.

The only possible way known to finish the game w/out boots is by using a glitched password to get all bosses weapons:http://tasvideos.org/2059M.html The way phantom grab work is not that wide, the way it work is by collecting an item at the same frame another item is spawning, this new item will spawn where u grabed the old item... that's why the boomerangs make that much possibilities in the current 100% TAS *sorry englando*

The logs are considered "enemy projectiles" and not "miscellaneous", so they can't be phantom grabbed.

You can skip dash boots on the PC Version I believe. I don't know if anyone would TAS it though. Hopefully one day someone will decide to take on that project.

No, I meant the logs at the beginning of the stage that ZX497 was asking about.

Ahhh, I see. Thanks for the input everybody, much appreciated! How does the boot skip work for the PC version, 4N6? Is there a video reference of some kind?

To be honest I'm not really sure all I know is it involves going on the ceiling some how. I don't have video reference of it I remember seeing a picture of it but, it was a long time ago.

Assuming you're talking about the normal level's door, does this activate the explosion sequence on the ship?

Ok so I was directed here as I am wanting to share something I discovered today. I did a bit of research before posting, and I can't find this documented anywhere so I figured I would submit it here for others to check out. Watching Any% speedruns out there for this, I grew even more intrigued as nobody was using this glitch. So I figured that either a) nobody knows about it, or b) its not useful. So if its already well known and I am just an idiot as it's not useful, I will happily delete this and move on :) It should be known that I am not a speedrunner obviously :) I made a crappy video of the glitch here. https://www.youtube.com/watch?v=Tgn-Ktl7Oyw&feature=youtu.be At the time of the recording, this was the third repeat. I did nothing special to set this up, just picked Flame Mammoth's stage, fought through to this point, jumped on the smasher and shot it. Next thing you know I was given the stage clear screen and the weapon. I then went back inside and it repeated no problem. I haven't tested to see what other weapon combos this works with or if you play the stage later

There's an emulator bug which carries this symptom in various forms. I haven't seen this particular version of it, but it looks just like the others.

From what I remember, it's always just been a bug regarding inaccurate emulation. He was playing on ZSNES, and I remember running into the same bug myself years and years ago while playing on ZSNES. It could possibly be related to this: http://board.zsnes.com/phpBB3/viewtopic.php?f=3&t=9809 So yeah, it can't be reproduced on console or more accurate emulators like Higan.

There are a lot of anti-piracy measures triggered when an emulator like ZSNES is being used. Here are some of them: https://tcrf.net/Mega_Man_X#Copy_Protection

http://www.twitch.tv/huurtheduur/v/52279424 New glitch that appears to freeze X's Y-axis speed while inside the ride armor. I don't know how to reproduce it(and apparently neither do the people in the video), but in the grand scenario it could perhaps be activated while moving upward to get the mech up on top of the roof to punch the igloo holding the heart tank and eliminate the Penguin revisit in 100%.
