The water in Launch Octopus's stage is a flat colored blue wall on layer 3 made transparent. Here's how it looks with and without the transparent variable on. You have to change a grand total of 1 color to get everything else in the water to be colored differently.

 

This is probably the wrong place for it, but here are the addresses for palette information and loading points in the rom.

LOADING POINTS
----
The loading point format is as follows, where A represents a hexidecimal number:
ABCDDEEFFGGHHIIJJKKLLMMNNOOPQ
A = Object loader value. Values do different things in different levels.
B = Tile loader value.
C = Palette loader value.
D = X location of Megaman X.
E = Y location of Megaman X.
F = X location of left side of screen.
G = Y location of bottom side of screen.
H = X offset of background. Background is
moved to the left by HH pixels before
X appears onscreen.
I = Y offset of background. Background is
moved up by II pixels.
J = Border for left side of screen. The screen cannot
move past this point, nor can X.
K = Border for right side of screen.
L = Border for top side of screen.
M = Border for bottom side of screen.
N = Forced X offset. Differs from H in that the
background will not try to correct itself based
on X's position. It's also applied after X appears
on screen, not before.
O = Forced Y offset.
P = Background scrolling modifier. Affects how background
scrolls. Needs more research.
Q = Teleport modifier. Affects how far down X goes after he
has been teleported.

Hey guys I can palette hack.

This is from a hack that turns the game into a Boss Rush. So far the only major things edited are the loading points for levels and the highway stage's palette, but as I learn more about hacking the Megaman X engine I hope to add a scoring system as well.

Unfortunately I don't really have a place to permanently upload what I've got so far.

 

Thank you, Krigo!

Got it uploaded. Yay. It's a very early version of course but there's still some notable stuff in there.

http://neonhoax.eu/BossRush/BossRush.SMC

Note that this ROM is played on what will be the Hard Mode of the game, meaning you get no parts, E-tanks, or heart tanks.

 

I've started to slow down on the amount of information I'm able to get from this ROM. Is there anyone here proficient in 65c816 assembly hacking or SNES hacking of any kind? Collaboration is key.

 

I hope the debug menu still exits in at least one of the SNES X games...


So I'm finally starting to find stuff related to level maps. These are the 32x32 blocks for Launch Octopus's stage. Each block is made of 8x8 tiles, and these large blocks go into the larger 256 x 256 blocks that make up the levels. Once I find out where the game uses the 256 x 256 blocks to construct the levels I can finally start level editing.

 

Looking through the mapping of Sting Chameleon's stage, it's obvious that it was used to test stuff in the game. It has some features that I haven't found in any other area's mapping.

http://img301.imageshack.us/img301/9395/scmap25co1.png
Image linked due to size.

First, note the garbled tiles in the upper area towards the end. These mark the places where the palette changes.
The yellow blocks are solid walls that X can't walldash on. They appear in other levels, but there's an additional two walls above the boss room. I guess this is to mark the end of the level.
Also note the long vertical line of garbled tiles. I don't know what this represents (Where the level ends vertically?)
Lastly (not pictured here), there's a mapping in the ROM for a 256x256 background piece that is identical to the boss room.

 

Yeah, they replace those areas. There's a similar 256x256 room in Flame Mammoth's stage with frost on it after you beat Chill Penguin.

 

I'm still working on hacking right now, but I'm also researching the differences between the 5 different revisions of Mega Man / Rockman X. Here's what I have so far. Note that it doesn't include stuff like translation changes, just programming ones. Also note that bugs common to all versions are not listed.

19.          of Flame Mammoth's room by hopping on the
