SV4 FILE FORMAT

Back to RCT TID home

The SV4 file stores the save game information. There is incomplete information about this file format. This page will be updated as information becomes available. The game saves SV4 files with RLE encoding. The decoded files have 2,065,676 bytes (0 .. 1F850B in hexadecimal).

000000..000001 - game time month (divide by 8 for years)

000002..000003 - game time day, counts in steps of 4. when this 16 bit value cycles, a month will have passed.

000004..000007 - game time counter, counts in steps of 1. does not begin at zero when scenario starts

000008..00000B,
00000C..00000F - contain psuedo random numbers which are related to each other.

000010..06000F - contains the game map. See the discussion below. The spatial dimensions used in the game are: one tile has 10 square meters of area; the height marks in the game are 4/3 meters (internal units are 1/3 meters).

060010..060013: an incrementing counter, two upper bits not used - not used as a trigger as far as I can tell

060014.. 198813 - sprite data structures. Each structure has 256 bytes. There are 5,000 sprite structures. Items stored in these structures include peeps (guest and staff) and ride vehicles. Ducks are also stored here. The vomit sprites are also stored here even though they are not moving objects.

1F8508..1F850B - these last four bytes of the file contain an additional checksum in CF/AA and LL saved games. This is in addition to the checksum added after the file is RLE encoded. This was not present in the original RCT files. This checksum is calculated by starting with the hex value 00000031 in the summation register. The summation register is rotated left 13 bits and then the byte of [unencoded] data structure is added to the low byte. This is done for the data from 000000 to 1F8507.

GAME MAP

The game has a grid of 126 by 126 tiles. The save file contains 128 by 128 tiles. The tiles around the perimeter of the game "board" are not displayed but are apparently needed to display the rock edges around the "board". The save file contains (among other things) a sequence of map elements. A map element data structure is used for all stationary items which appear on tiles. The sequence is: rows of columns; where each column contains a variable number of map elements (at least one). Each map element has 8 bytes identified below as bytes 0 through 7. The map element data structure begins at address 000010. The first row consists of perimeter tiles so there is only one map element per tile. The second row consequently begins at 000410. The length of the second and subsequent rows depends on how many map elements are at each tile. I have used the arbitrary designation that the map begins at the SouthWest corner and the first row goes from West to East.

byte 0 - map element type identifier -
upper two bits: indicate quadrant for smaller objects and are used as the two highest bits for the color code on geometric objects. NOTE: all geometric edge (wall) objects on a tile will have the same color; a geometric scenery object can have a different color from the geometric edge objects. Also used to indicate direction a queue entry faces. SURFACE tiles - the upper bit is a flag to use extended edge types, see the description under "byte 4". TRACK pieces: the most significant bit is set to indicate lift chain.
00 = entire tile or SW quadrant -or- facing West
01 = NW quadrant -or- facing North
10 = NE quadrant -or- facing East
11 = SE quadrant.-or- facing South

middle four bits: indicate type of element
0000 = surface tile
0001 = path (& road)
0010 = track element  or shop/stall
0011 = scenery item (single tile)
0100 = ride entry/exit, Park entrance
0101 = fence(s)/wall(s)
0110 = scenery item (multiple tile)
0111 = banners

lower two bits:

In Loopy Landscapes, bit 0 of surface tiles is used to extend the surface type - see the description under "byte 5"

byte 1 - The most significant bit is set to indicate the 'last' map element at this tile position. A single -or- a sequence of 8-byte map elements will be present for each tile position. The four bits of the lower nibble are used to indicate which quadrant(s) are used. bit 3 = NW, bit 2 = SW, bit 1 = SE, bit 0 = NE. The middle two bits of the upper nibble are used to indicate the support type for paths: X00X= normal (truss), X01X= wood post, X10X= steel post, X11X= bamboo post. bit 6 is set for "indestructible" track elements (used in certain scenarios).

byte 2 - base height of this element. Surface elements have heights which are multiples of 4. An element (eg. a large tree) which is located at the center of a sloped tile would have a base height which is 2 greater than the base height of the sloped surface element. A small tree on a slope would have a base height either 1 or 3 greater than the surface element depending on which quadrant it is in.

byte 3 - clearance (construction) height for this map element. {A value of zero is used for perimeter tiles.} The vertical space between the values in byte 2 and byte 3 is occupied by this element. No other space filling map element is allowed to occupy this range.

byte 4 - for multiple-tile scenery elements: byte 5 contains the sequence number for the part of the scenery object to be rendered at this tile. The number of tiles occupied are in brackets.
00 = Roman colosseum [12]
01 = house [6]
02 = Sphinx [8]
03 = house [8]

1F = urban house 2 [4]
20 = satellite [4]
21 = space capsule [1]
22 = tenement [1]

byte 4 - for single-tile scenery elements

byte 4 - tracks: the track element code number. {includes: shops, info kiosk and ride bases}Track pieces which occupy more than one tile use byte 5 to indicate which section of the track element is located at this tile.

byte 4 - park/ride entry/exit: for park entrance, byte 5 indicates which section. Otherwise, the remaining bytes are 00's.
00 = Ride entrance
01 = Ride exit
02 = Park entrance

byte 4 - paths - upper nibble:
00 = queue
01 = tarmac
02 = dirt
03 = crazy tile
04 = roads (not available to user)
05 = tile

byte 4 - paths - lower nibble: bit 3 is set for a queue entry, bits 2, 1, 0 indicate the slope:
0 = flat
4 = up to West
5 = up to North
6 = up to East
7 = up to South

byte 4 - fences/walls: the upper three bits are the three lower bits of the color of geometric objects.

byte 4 - surface tiles - upper 3 bits: the edge style of surface elements. 000 = rock, 001 = brick, 010 = iron, 011 = wood, 100 = grey wall, 101 = yellow wall, 110 = black wall, 111 = red wall. In Loopy Landscapes, the MSB of byte 0 indicates an extended set of edge styles. If that bit is set on a surface element, use the following: 000 = Ice, 001 = purple wall, 010 = green wall, 011 = brown stone wall, 100 = grey stone wall, 101 = skyscraper A, 110 = skyscraper B, 111 = not used.

byte 4 - fences/wall - lower 5 bits: the slope of the surface. Thes same value as below.

byte 4 - banners: index into banner data structure (100 eight byte structures beginning at 19B57C)

byte 4 - surface tiles - lower 5 bits: the slope of surface elements. There are 19 possible tile slopes. (The stored tile height is the lowest point of a surface tile.) The lower four bits correspond to corners of the tile. If the bit is set, that corner is elevated by one unit. The case of all four bits being set is not used. If the fifth bit is set, three of the four lower bits will be set; and the corner opposite of the zero bit is elevated by two units rather than one. The image below shows the slopes as viewed from the SouthWest corner.

byte 5 - surface tiles - upper 3 bits: the terrain type for surface elements. 000 = grass, 001 = sand, 010 = dirt, 011 = rock, 100 = martian, 101 = checkerboard, 110 = dirt/grass clumps, 111 = roofing tiles.

Tiles within the park boundary have values which increase with time.(Least Significant 3 bits: 0=mowed, 1,2,3=clear, 4,5,6=clumps, 7=reserved)

byte 6 - scenery objects: this byte contains the color

byte 6 - fences/walls - upper nibble: the lower four bits (N₃..N₀) of the North edge element code.

byte 6 - fences/walls - lower nibble: the lower four bits (W₃..W₀) of the West edge element code.

byte 6 - paths - upper nibble: the bits are set if the path extends in that corner: bit 3 for SW, bit 2 for SE, bit 1 NE, and bit 0 for NW. Note: on "road" paths, the center stripe is drawn on the appropriate edge when two (and only two) adjacent corner bits are set.

byte 6 - paths - lower nibble: the bits are set if the path extends in that direction: bit 3 for South, bit 2 for East, bit 1 for North, and bit 0 for West. For example, a path which extends to the South and to the East would have 1100 for these four bits.

lower nibble: each bit indicates presence of property boundary fence: bit 0 = North fence, bit 1 = East fence, bit 2 = South fence, bit 3 = West fence

SPRITE DATA STRUCTURES

256 bytes for each sprite. This data structure is used for peeps, ducks, vomit, vehicles (each car of a train, etc.)

[NOTE: subtract 4 from all of the index numbers. I made a mistake! I will leave the indices as they are for the time being. It is easier to read addresses from hex editors if I leave this offset in place.]

04 : Sprite Identifier (00=vehicle [includes golfer & golf ball], 01=peep, 02=duck & 'flying text', 03=vomit/trash, FF=unused)

26,27 : Text string index: 00 – Handyman, 01 – Mechanic, 02 – Security, 03 – Entertainer, FF - Guest. - look up custom string if upper four bits are: 1000. (use only the lower 10 bits for index into string table). If the upper byte is between A0 and DF then it is a "real name" and the lower 10 bits indicate the first name while the upper 6 bits are processed to determine the last initial. An easy way is to shift the word right by 10(decimal), then subtract 28(hex). The result will be between zero and fifteen and is used to look up a Capital letter. (vowels and less common letters are not used)
