The transcription is much appreciated. I started my own last week, but I didn't get 'that' far into chapter 29.

Tron: Show me your power!
Tron: Now, go get 'em!
Tron: Ohhh, now! King Servbot!
X: Do you want to take the lead this time Zero?
X: Victory favors the bold. That's the way combat is.
Zero: Well, that could have gone better, but there's no problem for now.
X: I always feel like I lean on you too much, Zero.
Zero: Don't worry about it. You can return the favor sometime.
Zero: Don't miss the target!
X: Can you stand the armor's full power?
http://youtu.be/7LIQdqPD-7k?t=17m9s??? (Vile): I'll give my own intro, thanks. I got my own mission here.
??? (Vile): My goal is to destroy him. Tear him limb from limb.
Tron: Vile? No way!
??? (Zero): Yes! The Maverick who teamed up with Sigma to destroy our organization.
??? (X): Cyberspace is overflowing with data. Where did all these people come from.
Tron: Huh?! Mega Man?!
??? (Zero): And that's not all. I was never expecting to see him again.
??? (X): ......
Vile: Zero. And you, X!
KOS-MOS: Zero and X. Searching database.
KOS-MOS: Zero is commander of the Special 0 Unit of the Maverick Hunters.
KOS-MOS: X, meanwhile, commands the 17th Elite Unit of the same group.
Servbot: And Maverick Hunters are guys who fight against out-of-control Reploids!
Vile: Commander, I see. How ironic that you should have Sigma's old post.
X: Vile! You were destroyed long ago! Why are you here!
Vile: I believe I've told you. I will never go away. Not untill I've killed you!
X: But why? Why are you doing this?!
Vile: To show you, X, that you are capable of nothing.
Vile: I am the one who will change the world!
Zero: X, don't listen to what that Maverick's saying.
Zero: If he's back in action, we'll just have to defeat him again!
X: But is that going to solve anything, Zero?
X: Reploids constantly destroying each other. It has to end!
Vile: Heh heh heh. Haaaa ha ha ha ha!!
Vile: Stewing in your own juices again, eh, X?
Vile: That hesitation is exactly what's ruined all of your potential!
X: Vile. I don't know why you hate me so much.
X: But I know what I have to do.
X: Because now I lead the 17th Elite Unit!
Chapter 20
The Maverick Hunters
Chun-Li: The Maverick Hunters. Are they like the police of this world?
Devilotte: More like a special forces group, I'd say.
Pai: And Vile must be some kind of notorious criminal.
Kogoro: Judging by their conversation, he's another guy who was killed in the past.
Batsu: What the hell, man? This is all making less and less sense!
X: "Another guy"?! Do you people know something about this?
Xiaoyu: Well, more like we're being swept up by it, I guess you could say.
Zero: I don't know who most of you are.
Zero: But some of you are in my data stores.
Zero: KOS-MOS of Vector Industries, Tron the air pirate, Princess Devilotte...
X: We can get the story later, Zero. If Vile is here, something bad is happening.
Zero: I hear you there. Try not to drag us down, guys!
Lady: Yeah, you too. Think we can trust them?
S"anger: Are they androids?
Tron: Reploids. They're robots, but they think, feel and act like real people.
Servbot: Ooh, I want to be friends with them! Can we be friends? Can we?
Demitri: Well, hopefully they live up to the "Hunter" name they call themselves.
X: I'll do everything I can. I'm afraid fighting is the only solution here.
Vile: You will all die. I refuse to allow anyone to interfere with me.
Ciseaux: Hah! Well, that's what you get when you name a robot Vile, eh?
Due: Shall we begin, then? We're just about at the right moment for it.
Due: Besides your "power" is beginning to manifest itself beautifully!
Mii: UGH, yes, we get it, foreshadowing, we're very impressed.
Ciseaux: Oooh, curse you! I'll nip your tails yet! Ahh, the repairs to be done.
http://youtu.be/vN5r7vdScxs?t=14m41s
Vile: Heh, heh heh! So this is me! This is who I am now!
Vile: Heh heh... Ha ha ha ha ha!
*Vile leaves*
X: How long's it been since we last saw him, Zero?
Zero: I couldn't say. But now we know what our next mission is.
X: You said it. No way can we leave Vile unsupervised.
http://youtu.be/vN5r7vdScxs?t=22m36s
Alisa: No other enemies in range. Operation complete.
X: Thanks for the help. Could I ask who you guys are now?
Zero: I want to hear everything you know about this.
Toma: Well, it's kinda complex. I still don't get a lot of it myself.
KOS-MOS: Wait. I sense a new energy source.
Jin: Someone else? Where is it?
Servbot: It's from that capsule!
Toma: Is this a transporter? There's something like this in the Geo-Fortress.
X: It's a data transport capsule. It's already offline, though.
??? (Aura): ...Ka...i...
??? (Aura): Ki...te...
Kite: Aura...?!
Aura: Kite... I...finally found you...
Zero: Who's that?!
Alisa*: Don't hurt her! She's our friend!
Aura: Kite, BlackRose... I'm sorry.
Kite: Aura! What happened to you?
Aura: I--I wasn't able to protect The World.
BlackRose: D--Did Skeith destroy you again?
Aura: Yes. What you see before you is just a segment of my data.
Aura: If this capsule were not here, none of my program would have escaped.
X: Whew! I wasn't expecting this capsule to go saving people's lives.
Aura: I can only thank you for being there for me.
Aura: Kite, use your bracelet. I have the coordinates to The World for you.
Kite: All right. I'll try it.
*Everybody is teleported*
Estelle: Is this a church?
X: No. I can sense that we're still in cyberspace.
Aura: Yes. This is The World.
Aura: But it is now beyond my control.
Kite: So we can't logout.
Aura: I'm sorry, Kite.
Cyrille: Can you fix this if you got your powers back?
Aura: If you can find the scattered segments of my program, yes.
Imca: Where are they?
Aura: There are four segments. I know of the location of three of them.
BlackRose: Are they here in The World?
Aura: You can take a Chaos Gate there. Let me take you to Mac Anu first...
*Everybody is teleported*

Vile: Heh heh, heh heh heh...
X: Vile?! Why are you here?!
Vile: I see all the arrangements have been made. Good.
Lindow: What's that mean? Did you have it all set up to enter the scene now?
Tron: What kind of business does a Maverick like you have here, anyway?
Vile: ......
Vile: Haven't you ever considered why I was resurrected?
Kogoro: Well, Due from Oros Phlox brought you back to life, right?
Vile: No. She and I share a common goal; that's all.
Vile: I stand before you out of my own sheer will.
Jin: Oh, don't be stupid. You can't raise yourself from the dead by will alone.
Neneko: Neneko has witnessed an amazing mystery, really.
Neito: It's the Feydoom's power at work.
Hsien-Ko: Oh, Neito! What power do you mean?
Neito: The Feydooms have restored their past selves within this network.
Neito: Fear, pain. The sadness of seperation, the morbid phobia of death.
Zero: So what do those emotions and the Feydooms have to do with Vile here?
X: Hatred, revenge, anger. Now I get it, Vile.
Vile: Yes. All of that stayed within me. It never went away at all.
Vile: That's all there is to it, X!
Yuri: So that obsession of his was linked up with the Feydooms, and here we are.
Zero: You're a sad man, Maverick. Being revived like that doesn't change your fate.
Vile: Maverick? You call me a Maverick, Zero?
Vile: Heh heh. Well, fine. You won't be saying that again after I'm done with you.
Zero: What?!
Kurt: This is bad. And what about Skeith? He's not doing anything.
Bahn: That's why we gotta take action first! Before anything worse can happen!
Vile: Heh heh heh.
http://youtu.be/K_DFfsZi8Xk?t=34m19s
Servbot: Environmental anomaly detected! Something else is coming!
Alisa: Its data signature is similar to Vile's!
Lady: Someone like Vile, then?!
??? (Iris): ......
Zero: ?!
??? (Iris): Zero. Zero. I so wanted to see you again.
Zero: Iris? It can't be! Iris!
X: Iris?! The Colonel's sister? That Iris?!
X: Zero! You defeated her during the battle against the Repliforce!
Zero: ......
Iris: Zero. You're there too, X?
Iris: Why don't we live together in a world just for Reploids?
Iris: I think we can do it. If we just us all the power gathered here.
X: Iris, what are you saying!
Zero: Iris, there's no world just for Reploids. It's only a fantasy.
Zero: And now look. All these worlds, mixed up together. There's just no way!
Iris: But can't we work to build it together, Zero?
Iris: The reason I'm here...is because of your hopes.
X: ?!
Zero: That... That's what I wanted?!
Zero: But if so... Then... What am I fighting for!?
Zero: No, no! I...!
Vile: What's wrong, Zero?
Vile: A Special A Class Hunter like you, refusing this lady's request? Pathetic.
Zero: Grh... Vile...
Vile: Yes. Let me see more of that anger. You're just the same as I am.
Zero: No! I... I...!
Iris: Vile, that's enough! Please stop!
X: Zero, calm down!
X: You can't lose here! You promised you'd stop me if I acted like that.
X: And now you're doing it first... I can't let you do that!
Zero: X...!
Zero: Nnghh...
X: Zero?! Zero, speak to me! Zero!
Zero: ......
X: (No, Zero...!)
Ichiro: X! What's going on? What happened to Zero?!
Sakura: And who is that girl, Iris?!
Gemini: What were you saying to each other? You both know each other?
Cyrille: Is she a Reploid?
Iris: ......
Skeith Zero: ......
Kite: (D-Did Skeith create that girl?)
X: I'm sorry! Zero can't move right now!
X: I need to guard Zero for now! Someone come here and relieve us!
Ryu: Huh?
Pai: Did you notice that, Ryu? From X?
Ryu: Yeah. What is this? That's definitely a "spirit" I'm feeling from him.
Alisa: That can't be. X is a robot.
KOS-MOS: It is part of the Reploid potential stored within X's and Zero's bodies.
Zero: Ngh, Iris...
Iris: ......
Toma: I don't get any of this, but it looks like trouble. We better save Zero!
Chris: It doesn't matter who, Someone has to help X out!
Vile: No, they don't. I need them to experience some more pain first!
Vashyron: That dude's crazy! Let's move, people!
http://youtu.be/npek0kRsaOI?t=29m11sX: Thanks a lot. Zero, are you all right?!
Zero: Ngh. I'm fine... I...
Zero: I... am a Hunter. I fight the Mavericks. It's what I was made for.
Zero: I didn't mean to look back on the past. I just couldn't let myself...
Iris: Zero.
Zero: iris. Let me tell you what I'm hoping for.
Zero: I want to make a world where no one has to go through what we did.
Zero: And that world is not going to be for the Reploids, Iris.
Iris: Zero...
Aura: ......
Kite: Aura?
Aura: You are not supposed to be here...
Aura: Your heart... It cannot stay here.
Iris: I know. I know I shouldn't be here, and that I shouldn't have met Zero.
Iris: But I'm still happy. I'm glad Zero's still the same as before.
Iris: And, as always, he will never lose.
Zero: ......
Iris: Don't worry, Zero. You have the strenght to overcome your destiny.
Iris: Goodbye, Zero. I'm glad I could tell you that.
Chapter 29
An Unbeatable Love
Aura: Iris' presence has disappeared from The World. She has been released.
Zero: Iris. I promise... I'll go to where you are someday.
Zero: But before then!
X: Zero...
Zero: Sorry, X. I wish you didn't have to see that.
X: It's all right, Zero. We better fight even harder for her sake.
Zero: Yeah. I'm not gonna abandon this case. Not until the very end.
Aura: Thank heavens...
Soma: Aura, are you all right?
Aura: It took awhile to rebuild my data, but I am fine now.
Aura: Now, Kite...
Kite: Yeah. Beat Skeith!
Aura: I will try accessing the inner core of the system.
BlackRose: Thanks. We'll handle this mess for you!
Akira: I'm not gonna pry in your business, Zero. Are you ready to fight?
Zero: No problem here. I'm back in the mission!
Zero: (I hope you're watching, Iris, from wherever you are right now.)
Zero: (No matter what future I blaze for myself...)

Perchance, do you know which chapter involves the infamous "rocket"?
-Zero quotes X4 verbatim a few times, so brace yourself. Also, Xtreme2/Soul Eraser doesn't seem to exist in this game's canon; its data files give the old outdated description of Iris falling for Zero after he saved her life, which clashes with MMX:OCW. X also doesn't appear to know Iris that well.
How does it clash with MMX:OCW? I don't believe those sources are really as "old" and "outdated" as you say. In other words: both should be true, at the same time.
-X and Zero meet Iris during the Erasure Incident.
-Iris and Zero dated afterward.
-She falls in love with Zero because of the Sky Lagoon Incident.
Am I missing anything? X himself has only ever been shown to converse with Iris while on a mission; they don't speak at all during X4. Likewise, we are not quite sure how much time has passed since the destruction of the Repliforce. X5 does not seem to have happened yet, however.
