You appear to be correct. Keen eye, since the image had different tiles than the ones in your picture.

Go ahead and reload 6.gif, though, since I strongarmed it to look correct (it took some hunting and patching to get it to look right).

So there we have it. If nothing else, Wario Land has an unused checkpoint room. Should probably take it to the next step so we can at least see if there's still a checkpoint object in there or not.

This is excellent. Thanks for taking the time to link levels with the data. I'm hoping similar information is in there somewhere too, since the game knows which maps to load for which course numbers.

If it's not too much to ask, could you label the remaining ones/copies as well just so we know what they are at a glance?

I know, right? Shit gets done when I have nothing better to do!

Though to be honest, there was something I should probably have been doing instead, which makes it all the more satisfying that it was successful.

Hm, I noticed that none of the data you posted from the Course 01 thing seemed to correspond to the music used in the stage (unless it was one of the unknowns and I overlooked it, but I didn't notice any sound related results with those), I was going to go through and map all the songs/search for any unused ones (though I'm going to guess there aren't any since the GBS has been available for years )

Mm, but SML2 and Metroid 2 share some content. IIRC the credits from one are left in the other... Probably all three are different versions of the same engine.

SML2's engine was built from Metroid's, and SML3's was built from SML2's...so yeah more or less a lot of code overlap, I'd imagine.

Immediately following the world definitions is a table containing door definitions. It's another list of addresses in bank 0x0C, but this time there's a surreal 1391 entries... They point to 24-byte structures:
032192 = Right-most door in the first area of Rice Beach 1 (low tide)


      1E E0 68 00 1E 60 08 00 00 00 E1 06 69 6E

00 56 00 72 00 40 0A 64 F6 44


1E      Wario destination door(/area?)

E0      Wario start Y coordinate

68      Wario start X coordinate

00      (Unknown)

1E      Camera/background destination door(/area?)

60      Camera Y offset

08      Camera X offset

00      Camera type (same as before?)

00      Graphics modifier (same as before?)

00      (Unknown)

E1      Background Palette

06      World tile bank

69 6E   World tile address              0x01AE69

00 56   Block/Coin tile address         0x045600

00 72   GUI, Coin Sprite tile address   0x047200

00 40   Animated world tile address     0x044000

0A 64   Block definition address        0x02E40A

F6 44   (Enemy pointer thing again)
A recurring theme here is that tilesets are loaded based on the data explicitly, rather than by ID. This seems somewhat wasteful, since there's only a handful of tilesets and they always seem to have the same banks/addresses/coins/GUI/animated/blocks/etc. each time they're used. A level editor would be able to pick up on this to simplify data exchange, I would think.

Still missing are object and door placements within levels. The "enemy pointer" loads the group of enemies that can appear in a given area, which affects their graphics and behavior (effectively swapping out enemies with different ones), but it doesn't actually seem to have anything to do with how they're positioned within the levels. Box contents and other objects are floating around in there somewhere too, and I'm keeping my fingers crossed for them to all be in the same place.

At ROM file address 0x01F1AA is the list of objects placed into Rice Beach 1 at low tide. However, the data seems to implicitly skip the top 16 rows of blocks (256 pixels), which might be the norm. Did anyone see any level data up there in the dump images, or is it always garbage?

The data is encoded with a simple placement algorithm that has 2 phases, which I'll refer to as Pair and Skip:
  • The decoded begins in the Pair phase, and alternates each time a piece of data is processed.
  • As with the world data, blocks are arranged left-to-right then top-to-bottom. There are 256 blocks in a row.
  • If phase is Pair, load one byte, which contains 2 object definitions (4 bits each). These apply to the next 2 blocks, starting with the high 4 bits of the byte.
  • If phase is Skip, load one byte, multiply by 2, and skip that many blocks.
With object IDs overlayed, level 1 looks like this (click for full image):



Object ID can be one of the following:
0 = Box: Coin (drop) / Nothing

1 = Object 1

2 = Object 2

3 = (Unknown/nothing)

4 = (Unknown/nothing)

5 = (Unknown/nothing)

6 = (Unknown/nothing)

7 = Box: Garlic Pot

8 = Box: Jet Pot

9 = Box: Dragon Pot

A = Box: Key

B = Box: Heart

C = Box: Star

D = Box: Coin (bounce)

E = Box: 10 Coin

F = Box: Bull Pot

Indeed, one of those "worth 10" coins can pop out of a box. Do any of those actually appear in the game?

Object 1 and Object 2 vary depending on what the aforementioned "enemy pointer" points to. This can be enemies, unlockable doors, huge blocks and moving platforms among other things.

If a box exists in the world data and doesn't have an object assigned to the same location, it will produce a single coin. In other words, unless otherwise specified, all blocks contain object ID 0.

It would appear (so to speak) that you can assign box contents to non-box blocks in the world data, which will cause a box to appear if you jump under it.

Still MIA is the master course data structure, which contains music, course number and door specifications.

There's a list of pointers at 0x01C199 (07:4199) containing addresses in the same bank of all the level object layers, conveniently in the same order as the ones in the world definition tables. This means we can easily line up world data with object data.

Indeed, it appears that skipping the top 16 rows of blocks is what we're supposed to be doing. I ran my program on Mt. Teapot 1 and found this:



The checkpoint object is definitely in there, but um... it's kinda floating up above the water a bit. I've uploaded an artist's conception of what it looks like to TCRF:

Thanks! I appreciate the encouragement: makes me want to keep going.

I know there's a lot of people who have the motivation to do the work, but simply don't have the know-how... We should think about setting up some kind of resource or seminar of some kind for hacking fundamentals.

*Blink*

Dod gammit, now I have to see if that information is in there anywhere.

The only way to know for sure what that object represents is to examine an "enemy pointer" that lands in the area. If it's one thing, that's an enemy. If it's another, it's a checkpoint. If it's yet another, it could be the switch block or one of the giant blocks or something...

I'll keep my fingers crossed and hope there's a transfer point that dumps you out there, 'cause if not, there's no way we're going to know for sure what's actually in that room.

GuyPerfect, for starters, you are awesome.

Also, I'd be interested in a beginner's course. I once upon a time had a tiny bit of this knowhow (I could convert codes from Pokemon Red/Blue to Yellow), but that's been many, many years now. I understand Hex, and that's about it.

Also, your avatar is awesome. I'm pretty sure I have that logo on my old, lousy, crappy McCrap Angelfire page from when I was what? 12? Yeah, a long, long time ago.

It's good for the nostalgia, though.

Looks like GoldS updated the list to document the duplicates. The indexes are all the same, if you add 43 to the normal ones. I suspect this is probably used as the alternate version for switch block levels, which would mean every level can be switched arbitrarily. The implications are quite delicious, so we'll have to wait and see how it works out.
__________

At 0x000534 (00:0534), waaaaaay at the beginning of the ROM file, is a list of pointers (86 entries) for course numbers. What exactly do those pointers point to, you ask? Get ready to facepalm:
00:058A 3E 01     ld  a,01

00:058C C9        ret

00:058D 3E 02     ld  a,02

00:058F C9        ret

00:0590 3E 03     ld  a,03

00:0592 C9        ret

00:0593 3E 04     ld  a,04

00:0595 C9        ret

00:0596 3E 05     ld  a,05

00:0598 C9        ret

(And so on...)

The game program loads the address, jumps to it, and executes the code there... which just in turn loads the course number via immediate data. They could have, oh, I dunno, used a list of bytes containing the course numbers in place of this code pointer->load code business, but they wanted to keep it fresh.

They used 5 bytes of ROM data to represent 1 byte of information per level.

These ld+ret blocks continue sequentially all the way up to 40, so to simplify course number translation, you can take the address from the table and process it with this formula: Course = (Address - 0x0587) / 3

As usual, the indexes are the same as for the other tables. Mt. Teapot 1, Course No. 7, has an index of 6, at which position is $059C. This becomes 0x059C - 0x0587 = 21 / 3 = 7.
_________

At 0x033E73 (0C:7E73) is a table of 43 pointers for level music. The data immediately following the pointers specifies the musics themselves, and the only ones present are the ones used in the final game. Their values and not-very-helpful names are as follows:
$7EC9 = Lake

$7ED5 = Beach 1

$7EE1 = Cave 1

$7EED = Cave 2

$7EF9 = Train

$7F05 = Boss Level

$7F11 = Cave 3

$7F1D = Cave 4

$7F29 = Beach 2

$7F35 = Cave 5

$7F41 = Syrup Castle

$7F4D = Cave 6

$7F59 = Sherbet Land

The music "definitions" look like they take up 12 bytes each, putting the next one at $7F65, but that crashes the game, so there certainly isn't any music defined there.

Well, hex is definitely something you'll need. Let me think on how to establish some lessons and I'll bring it up again later.

EDIT:

D'aw! Foiled again! The room isn't unused after all: there's a door leading to it. From the checkpoint area, go down into the water and head left. Break the blocks on the bottom to reveal the door.



I'm still working out the details as to how the doors are placed into levels, but I'm this close to having it all figured out to the point that we can make a level editor.

Okay, got it. At 0x030F30 (0C:4F30) is a table of door destination pointers. There are 32 pointers per level, and entries for all 86 of them.

Door placement in levels is somewhat arbitrary: the levels are divided up into regions of 256x256 pixels (16x16 blocks), meaning it's 16 regions wide and 2 regions tall. Remember, we're discounting the uppermost 256 rows of pixels because screw those mofos we don't love them anymore.

Within those regions can be doors. Or not. The door can be anywhere within it, as long as it's one of the 16x16 blocks, and its destination info is read from the table at the corresponding location (left-to-right then top-to-bottom). There can presumably be any number of doors in a particular region, and they'd all go to the same destination, but the level designers never used more than one. This is something to be tested.

The destination information, documented in an earlier post, includes the target region, which will initialize the background map and position Wario and the camera. A door can lead to a location that doesn't have a return door.

If the taget region is out of range, the game will handle it accordingly. It's got some hard-coded behaviors for regions 32, 33, 34, etc. (I don't remember how many), which includes the exit door, and apparently 255 will cause the door to not go anywhere at all.
__________

Okay, let's see... We have the following information:
  • Course Number
  • Music
  • World graphics (start and door transfer)
  • World data
  • Object and enemy data
  • Door data
  • (Presumably switch block status, but this needs to be tested)
And the following information needs some more investigation:
  • Specifics of Wario/camera positioning on region entry
  • Scrolling boundaries
Both of those are known in the data we already have; we just need to know exactly how they're represented in the bytes.

Aaaaaand then we can make a level editor. I'm thinking Java for a number of reasons: it runs on everything, it's easy to use, and all the GUI stuff is built in. We could put the code up in a spot where everyone can get to it... not necessarily a version-controlled repository or anything, but something for people to see and contribute to.

Aaaaaaand done. Turns out there *is* additional information pertinent to scrolling boundaries.

At 0x030000 (0C:4000) is a table (43 entries) of scrolling boundary types for each of the 256x256-pixel regions within the levels. Each entry is 32 bytes, and the bytes themselves indicate how the scrolling stops in that region:
Bit 0 = Boundary on right side

Bit 1 = Boundary on left side

Bits 2-7 = (Nothing)

Since there aren't boundary definitions for the duplicate/switched worlds, it's important to make them mirror each other so the camera behaves correctly.

Considering that each level is only 2 "regions" tall, and that door destinations target entire regions, it seems unlikely that you could wrap a single room using one tileset completely around another room using a different tileset. At least while keeping the circumscribed room hidden from view at all times. The implication is that a combination of door destinations and region scrolling boundaries can probably be used to reliably configure the graphics of a level display. It'd take a sort of flood fill to detect where Wario is capable of traversing, however.
__________

A more complete description of the basic world definition is as follows:

0x030792 = Rice Beach 1 (low tide)


      03 00 52 00 54 00 72 00 4A 10 01 0A 46 01

60 00 28 08 20 00 E0 00 00 02 00 00 07 E1 CF 44


03      World tile bank

00 52   World tile address                      0x0C1200 -- 96 at $9200

00 54   Block/Coin tile address                 0x045400 -- 32 at $9000

00 72   GUI, Coin Sprite tile address           0x047200 -- 23 at $8B00

00 4A   Animated world tile address             0x044A00 --  4 at $9200

10      Bank number of world data

01      Index of world data                     0x040002 -> 0x04081E

0A 46   Block definition address                0x02C60A

01      Wario starting Y region

60      Wario starting pixel Y

00      Wario starting X region

28      Wario starting pixel X

08      (Unknown)

20      Graphics modifier

          Bits 0-3 = (Unknown/no effect)

          Bit 4 = Wario's colors inverted

          Bit 5 = Wario is right-facing

          Bit 6 = Wario is vertically flipped

          Bit 7 = All sprites behind background

00      Camera Y region (0-1)

E0      Camera Y scroll

00      Camera X region (0-15)

00      Camera X scroll

02      Scrolling boundary type for initial region

00      Camera Type

          Bit 0 = Train bumps

          Bits 1-3 = (Unknown/no effect)

          Bit 4 = Wario stays center screen

          Bits 5-7 = Auto-scrolling (all three identical?)

00      Wario start status

          00 = Standing

          ** = Swimming

07      Animated world tile frame delay

E1      Background palette

          Bits 0-1 = Color 0 = 1

          Bits 2-3 = Color 1 = 0

          Bits 4-5 = Color 2 = 2

          Bits 6-7 = Color 3 = 3

CF 44   (Pointer to enemy definitions of some sort; bank?)

In all cases, the initial configuration of the screen/world scrolling should be such that Wario is visible within the window rectangle.

The alt attribute should be used to give a short description
of an image; longer descriptions should be given with the
longdesc attribute which takes a URL linked to the description.
These measures are needed for people using non-graphical browsers.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
