    Hello there, my little friend. Member
    Videos for Hellfire Commentaries.
    That's sort of what I'm starting to think. The white city is concept art. Nothing more.

    I always thought the Hoganmer was the Sniper Joe of the X series. I'd love to see that code implemented into a hack of Megaman X.

    The loading point format is as follows, where A represents a hexidecimal number:
    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.
  6. Yuzu


    I have a place for you to upload the hack to, PM'ed you.
  7. GoldS


    Thank you, Krigo!

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

    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.
  8. GoldS


    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.
  9. Yuzu


    Your welcome, I don't normally just give out hosting for free but this project is something that's worth it :(

    I remember finding that debug text in the ROM, too, but couldn't find its associated code. It might not exist anymore. :objection:

    However, I DID find working debug code in Mega Man 7 a few years ago, which is very likely similar to MMX's. Behold!


    Sprite test: C00620:02
    Lets you view all the sprites in the game and tweak their various parameters. I forgot what all the buttons do, but it's not hard to figure out.


    Sound test: C00620:04
    Pretty self-explanatory. There's supposed to be a cursor there, but for some reason it's invisible (maybe there's some initialization code I'm missing).

    Mega Man 6 has a very similar sprite viewer/sound test, but unfortunately I lost the information on how to activate it (I couldn't find the original entry point for the code, so I did some voodoo bankswitching and memory poking to make it appear). I have a screenshot, though:


    I've found a lot of debugging stuff in other SNES games, as well as a few NES games, including an arcade-like test mode for Final Fight and a stage select for Super Castlevania IV. Most of my notes seem to have been lost over the years, though. Perhaps I should start a separate topic for the ones I do have...
  11. GoldS


    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.
    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.

    Interesting stuff. What's with the rooms in the bottom-left corner?

    I assume they replace the areas on top after you beat Launch Octopus?
  17. GoldS


    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.

    As far as I know, Zero was meant to be the main character. X was added afterwords. So, I'm not surprised there are leftovers.

    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.

    Code (Text):
    1. JP 1.0
    3.         REVISION BUGS
    4.         *The powered up S.Ice platform does not
    5.          self-destruct if it's used to kill
    6.          a boss. This can lead to a bug when
    7.          fighting Storm Eagle where the player can
    8.          get credit for defeating him after dying.
    9.         *Bug occurs if Sigma and X are killed at the
    10.          same time -- the boss is defeated, but the
    11.          player does not regain control and can't
    12.          advance the cutscene dialogue.
    13.         *Glitch password is present -- several
    14.          passwords can start out X with either 0
    15.          life or max life and all weapons / subtanks
    16.          depending on if the game demo was accessed
    17.          or not.
    18.         *X can walk on the ceiling in the beginning
    19.          of Flame Mammoth's room by hopping on the
    20.          Utuboros heads and climbing up the tube. Walking
    21.          right and climbing up an invisible wall leads
    22.          to the central room with the palette and enemy
    23.          graphics incorrectly loaded, as well as an
    24.          incorrect lower Y boundary.
    27. JP 1.1
    29.         FIXES
    30.         *Fixed the Storm Eagle S.Ice bug by having
    31.          the platform destruct when the boss's
    32.          health reaches 0.
    33.         *Fixed Sigma double death bug. Sigma can no
    34.          longer be hurt when player health reaches
    35.          zero.
    36.         REVISION BUGS
    37.          *Glitch password is present.
    38.          *Flame Mammoth ceiling glitch is present.

    52.          to 88 pixels to fit in more text.
    53. US 1.1
    55.         FIXES
    56.         *All US 1.0 version differences.
    57.         *Fixed Sigma double death bug.

    59.         *Glitch password is present.
    60.         *Flame Mammoth ceiling glitch is present.
    62. ----
    64. EU 1.0
    66.         FIXES
    67.         *All US 1.1 version differences.
    68.         *Removes the glitch password as a valid
    69.          password.
    70.         *Fixes Flame Mammoth ceiling glitch by making
    71.          the upper part of the tubes solid.
    72.         OTHER
    73.         *Epilogue text is formatted differently than
    74.          in the other US versions due to PAL timing
    75.          differences.
    77. ----
    79. Version Timeline (speculative)

    83. US 1.0 based off JP 1.0
    84. EU 1.0 based off US 1.1

    Wasn't there an EU version of 1.1? Or my ROM I downloaded was incorrectly labeled.
