File format

The file is in this basic layout:

Data type Description
UINT16LE iFlags Flags indicating music, backdrop and other stuff
UINT16LE iMapWidth Map width in tiles
UINT16LE iActorSize Number of UINT16 values in the actor block
ACTORDATA actorData[] Variable-length array of all the actors in the level
BYTE bgLayer[65528] The map data for the background layer

The iMapWidth values in the original Cosmo levels is either 64, 128, 256 or 512. The "view window" in the game is 304x144 Pixels, so the minimal map width would be 38. However, the game will only recognize the values 32, 64, 128, 256, 512, 1024 and 2048. Any other value will not be handled by the game at all, thus leaving a vital variable uninitialized. However, the values 32 and 2048 should never be used in a level, since the width or height of the level would be smaller than the viewport.

The iActorSize values are reliable for all the original Cosmo level files (Version 1.20). Since the game loads the entire actorData array into a block of 65535 bytes, the iActorSize value must be less than 32766. Larger values would lead to memory corruption.

The map data found in the original level files is actually sized 65528 Bytes or 32764 Words, but the game will read it a block of up to 65535 bytes. Each Word entry in this block is divisable by 8 (see #Mapping cell values to tiles).

Level Flags

The structure of the bits in the iFlags value is as follows:

[ mmmmm | ppp | yxr | bbbbb ]

m: music index
p: palette animation type
y: y-scrolling backdrop
x: x-scrolling backdrop
r: rain
b: backdrop index

Assuming the iFlags value was read as a UINT16LE, the value can be split like this:

rain      = (iFlags & 0x20) != 0;
backdrop  = iFlags & 0x1F;
scrollX   = (iFlags & 0x40) != 0;
scrollY   = (iFlags & 0x80) != 0;
animation = (iFlags >> 8) & 7;
music     = (iflags >> 11) & 0x1F;

The indices for music and backdrop refer to an array of filename strings stored in the executable. You can find them by searching for the first filename in each array. For backdrops, the first filename (index: 0) is BDBLANK.MNI, for music it's MCAVES.MNI. Note that some backdrop files are not used by the games. The complete list is:

Background Layer

The bgLayer block contains the grid/cell data:

Data type Description
UINT16LE iMapData[32764] Actual map data

Each "element" in iMapData refers to the foreground and/or background tile used in a single grid cell. The grids are arranged left to right, top to bottom, so the index can be calculated by this formula:

int iIndex = (y * iMapWidth) + x;
iMapData[iIndex] = <new value to set at x,y>

The map data in the original Cosmo level files is a constant 32764 UINT16LE cells long (65528 bytes), and the engine will never read more than 65535 bytes. However, the game calculates the map height using this formula:

int iMapHeight = 32768 / iMapWidth - 1;

Since the width of the map is always a power of 2 (min. 64), you can see that each of the original level files is "missing" 8 Bytes (or 4 Words). That means the last line of the map will always be missing the last 4 tiles. The game ignores that last, incomplete line (hence the -1 in the formula). However, in one level (A8.MNI), there is an actor placed in that last line. Since actors are saved as individual structures instead of a grid, that actor will still be loaded by the game. For editing a level, you should make sure the last line is visible, so that it's possible to place actors in that line or remove them from there. Using a buffer of at least 65536 bytes for the level tiles is highly recommended for this.

Mapping cell values to tiles

The method of mapping elements in the iMapData structure into tiles is fairly straightforward. Each cell value is a pixel index into the tilemap. Imagine the tileset laid out left to right all on the one row. Since each tile is 8x8 pixels, at 16 pixels into the image, the third tile will begin (x = 0 for first tile, x = 8 for second tile, x = 16 for third tile.) Assuming the solid/unmasked tileset graphics are layed out as an 8 pixel wide column, the cell value is essentially a pixel y-coordinate into the solid/unmasked tileset.

Note that in the tileset file, the solid tiles are made up of 2000 4-plane (16-colour) images, and these are followed by 1000 5-plane images (16-colour + transparency.) The game interprets any value smaller than 16000 as an index into the solid/unmasked tileset. Any other value will be treated as an index into the masked tileset (the offset 16000 is subtracted, of course). The cell value will be zero for the first solid tile, it will be eight for the second solid tile, it will be 15992 for the last solid tile, and it will be 16000 for the first masked tile.

This means that if the solid and masked tiles have been treated as separate images, a check will need to be performed so that any cell value below 16000 is loaded from the solid tileset, and any value larger than this is loaded from the masked tileset (after subtracting 16000 from the cell value, to put it at zero for the first masked tile.) However, since the masked tiles consist of five planes, the values for the masked tiles are at multiples of five tiles (tile #0 (x=0) is the first tile, tile #5 (x=40) is the second tile.) The following formula can be used to convert the values into tile numbers once they stray into the masked tile area:

#define COSMO_TS_SOLID_NUMTILES   2000 // 40x25
#define COSMO_TS_MASKED_NUMTILES  1000 // 40x4

tile = cell_value / 8
  // Once we're in the masked tileset it counts up in multiples of five planes
// Now 'tile' will be between 0 and 2999 inclusive

As an example of a few tile values:

Cell value Tile number Tileset Index Comments
0 0 N/A N/A See through to map backdrop
8 1 Solid 1 First solid tile, note increment of 8
16 2 Solid 2 Second solid tile, increment of 8 again
15992 1999 Solid 1999 Last solid tile
16000 2000 Masked 0 First masked tile
16040 2001 Masked 1 Second masked tile, note increment of 40
16080 2002 Masked 2 Third masked tile, increment of 40 again
55960 2999 Masked 999 Last masked tile
56000 N/A N/A N/A Should never get a value this size or larger

Note that while the cell value cannot be out of range for the solid tiles/background layer (since any values larger than 16000 will be loaded from the masked tileset) the cell values for the masked tileset have no such restriction. (Although obviously out of range tiles will not be drawn correctly by the engine!)

Another thing to keep in mind is that the game will simply draw the background for any cell value smaller than 80. The first ten tiles in the tileset are never drawn in the game, but they should be drawn by a level editor.


  • The first ten tiles in the solid tileset is used as transparent tiles. The game does not draw these tile, so any cells with this as the background cell will be where the map backdrop shows through. If you wish to draw the map with the backdrop in-place, remember not to draw tile #0 over the top of the backdrop.
  • The solid tiles #1 to #8 are used to define a path, along which the platforms move in the game. The path should be laid out in a loop and should never lead to a non-direction tile. If tile #0 is part of the path, the platform will stop moving once it reaches that cell. Any tile larger than #8 will lead to the game reading memory beyond an array boundary, which will result in undefined behavior.

Actor data

The actorData block is in the following format:

Data type Description
UINT16LE iType Type of actor
UINT16LE iX X-coordinate of actor (in tile units)
UINT16LE iY Y-coordinate of actor (in tile units)

Because the iActorSize value in the header is in UINT16s and there are three UINT16s per actor, the number of actors can be obtained quite simply:

iNumActors = iActorSize / 3

This is exactly how the game treats this value.

Mapping Actor Types to image indices

For the ActorTypes from 31 to 296 (inclusive), you can get an image index from ACTORS.MNI and ACTRINFO.MNI like this:

ImageIndex = ActorType - 31

However, this does not work for every ActorType. Some share the same images (e.g.: normal stars and falling stars), some use flipped versions of other images (like the pink eye plants) and some are invisible in the game. In either case, the index in the ACTRINFO.MNI will be "empty". You will either have to include hard-coded info to draw these, or just draw something else (like the actual ActorType as text).

List of Actor Types

This is a list of all the actor types that are actually used by the game. Any value not listed here will be ignored by the game.


  • Using more than 10 platforms or more than 10 mud fountains (total) in a level will lead to memory corruption.
  • There can be up to 199 lights in a level (if there are more, the game will ignore the rest).
  • There can be up to 410 actors in a level. Anything with a type value of 31 and above counts as an actor, but invalid/unused types will not take up an actor slot. The game will stop parsing the actorData array immediately after spawning actor #410, ignoring any other data that might be left in the unparsed part of the array, such as platforms, mud fountains, ligths and even Cosmo.

This file format was reverse engineered by Dave Bollinger. Most of this info came from the Duke II specs on his website, with Malvineous working out which bits to remove to read Cosmo maps.
