Mega Man X general research topic., Now with more hacking (and also a hack?) Options

[GoldS]

I'm working on hacking/researching the 3 SNES Mega Man X games. Here's some stuff I found.

MEGA MAN X1

Hoganmer


This enemy can jump, but for whatever reason this never actually happens in-game. The code for it still exists in the game though, and can be easily triggered. He will jump a short distance (32 pixels?) towards X, then when X is in range, fire his mace-ball thing.

Here is a youtube video of this behavior in action.

Lost Zero charging palette?


Zero has two palettes in the ROM that aren't used in-game at all. Presumably they are for some kind of charging effect. In the final game, his head crystal glows to indicate charging.


What it might have looked like.

The third Anglerge


There is both data and a palette for a third kind of Anglerge boss in the game. The subID for this Anglerge is 129, while the subIDs for the two Anglerges in the final game are 128 and 130. This Anglerge only blows air at X. Since the first Anglerge sucks air in, and the second Anglerge both sucks air in and blows air out, this was probably meant to go in between the two.

Tombot Generator


No idea where this was supposed to go, and the graphics won't load up correctly. This object is closed at first. When it opens up, it fires out two Tombots in one direction (which direction depends on the subID), then closes again. X can only damage the object when it is open. When it is destroyed, it starts smoking from the bottom for a bit, then stops.

Flying drill enemy


Probably the most interesting find. I hope I can find the graphics to this thing, it has a really cool looking animation cycle. This enemy doesn't appear at all in the game, and its behavior is completely unique. It has the same ID as the Sine Faller enemy, but has a subID of 1. The enemy falls down from the ceiling and swoops back and forth. When it collides with the ground, it drills into it, leaving only a small part of its sprite visible above ground. It only takes 1 hit to kill.

That's it for now. I'm bound to find more stuff as I keep delving deeper into the ROM.

Very cool stuff. I'm a big fan of the X series and would love to see what else you have. Nice work.

[Shade]

Very, very nice; and very interesting. I'm a big fan of the X series as well, so I'll be tuning in as well should your work uncover anymore neat tidbits.

Keep it up!

[GoldS]

I found the level that the drill object's tiles load at: Launch Octopus'.


It's a jellyfish robot! That is a drill! Jellydrill!


Look at him go!

The enemy graphics are loaded at the start of the stage, and are used up to the point where you face the first Anglerge boss. How much of Launch Octopus' stage was cut out anyway?

Maybe they thought the stage was too hard as is since it's almost completely under water? Though I always thought that the under water physics made tha game easier, not harder.

Nice work, btw. Are you planning on making a full blown disassembly?

[Metal Knuckles]

The jumping Hoganmer is the coolest thing I've seen here. It's a shame they had to cut it from the final.

[Hybrid Project A...]

Oh shit I love this stuff, I hope you find more. Have you looked at some of the other X games?

[GoldS]

I've found stuff up to MMX3.

This object is from MMX2:



This is the object with ID #1. It always loads the large weapon refill graphic. I'm guessing it's a test object for something. From the first orb, seven more orbs are created downward. The first orb is the anchor.



Each orb moves seperately, except the anchor orb, which doesn't move at all. Together they move in a wave like motion...



...in the direction of X.



This object has HP and can be destroyed. The anchor sphere is the first to be destroyed, followed by the connecting spheres.

Interesting object.

[Xkeeper]

Can we start getting patch codes for some of this? It's some really interesting stuff, but I usually find it more interesting to be able to play around with it. =P

[Phos]

I'm pretty sure I've seen hognmers jump in game. I haven't played Megaman X in a while, though.

[GoldS]

Okay...for Mega Man X, these codes work for ZSNES...

Object 1 ID: 7E0E72XX
Object 1 subID: 7E0E73YY
Object 2 ID: 7E0EB2XX
Object 2 subID: 7E0EB3YY
Object 3 ID: 7E0EF2XX
Object 3 subID: 7E0EF3YY
Object 4 ID: 7E0F32XX
Object 4 subID: 7E0F33YY
etc...

You have to convert the IDs and subIDs to hexadecimal since I just copy-pasted from my notes on the game. Sorry.

Note that if you place an object that's not supposed to be in the level, its tiles won't be added correctly and you have to disable layers 1 and 2 to see it at all.

Now onto something else I found, again dealing with Launch Octopus' stage.


This is a duplicate boss entry room. It's directly above the actual boss entry room.


Left over from an earlier version of the level, I guess. It's definitely unused.

[GoldS]

I found some debug text in the room, and I've found a way to sorta enable it. Now I have to find out what activates it for real.

[Zycor]

awesome stuff, I'm betting the unused Jumping would've been to act even more like Sniper Joe from the classic series.

[Skaarg]

It'd be awesome if there was any leftover stuff from the early beta pictures you see of the white city for the intro level.

[GoldS]

It'd be awesome if there was any leftover stuff from the early beta pictures you see of the white city for the intro level.

I've looked through the level palettes, what objects are loaded in levels, etc. and have found no evidence of anything related to the white city. It might be the Dust Hill Zone of Megaman X.
