Scripts Variables

This page contains or will contain a comprehensive analysis of the 8 resources in Myst (and the two added in Myst ME).

Both Myst and Myst ME use little-endian byte order in the files (by contrast to the big-endian byte order used in Riven and the Mohawk format), although the data itself is stored in properly formatted Mohawk format (don't let the .dni or .dat file extension fool you). The packages in Myst ME are:

  • CHANNEL
  • CREDITS
  • DUNNY
  • INTRO
  • MECHAN
  • MYST
  • SELEN
  • STONE
  • SYSTEM

The resources are on the left (MJMP and PICT are new in ME). None of the resources are named except for the MSND/MJMP resources.

CLRC

All CLRC resources follow the pattern:

short u1
short u2
  • u1 and u2 are both 1, 6, 7, 8, 9, or 14 for all files

EXIT

I think these are variables, although that seems unlikely because SELEN has no EXIT resources.

Case studies (all of them)

Note: these are presented as resource_index.length short... where the data is broken into shorts and displayed in decimal.

INIT

These are more likely variables. They do not have names like in Riven.

HINT

short rc record count
  • rc is wrong in:
    • CHANNEL 78 231
    • MECHAN 109
    • MYST 2 28 38 43 45 49 106 109 149 150 173 175 206 231
    • SELEN 172
    • STONE 10 12 18 59 89 91 106

records are

short rid record index
short u1
  • the rid's start at zero and go up, but there are exceptions.
    • CHANNEL 78 144 231
    • DUNNY all minus 1 5 7 18 19
    • MECHAN 109
    • Myst 2 28 43 45 49 78 111 171 173 175 184 206 229 235
    • STONE 10 12 18 59 89 91 106
  • the u1's all appear to be one of 0, 2, 3, 200, 300, 400, 500, 600, 904, 905, 999, or FFFF (-1)

MSND

It is interesting to note that all MSND resources in the whole game are named except for INTRO 1 (the linking sound). In all the other packages, this sound is labeled "transprt7" (in MYST) or "transprt1" and "transprt2" (which all appear to be the same, although transprt1 and transprt2 are separate resources in the package).

RLST and VIEW

There are the same number of RLST and VIEW resources in all packages, which leads me to believe that they are locked together by index like HSPT and CARD resources in Riven.

RLST

I think these contain hotspot data (i.e. HSPT).

short count_of_records

record type 1

8 1 < 31 276 163 333> 0 FFFF 0 103 2 3006 <0 0 132 57> 3005 FFFF
8 1 <417 260 544 333> 0 FFFF 0 103 2 3004 <0 0 127 73> 3003 FFFF
  • this replaces part of the image (in this case <417 260 544 333>) with part of another image (in this case 3004 <0 0 127 73>) based on a variable (103 2 plays in here somewhere)

record type 2: (simple hotspot)

short dir 1=left, 2=right, 5=forward
short type=2
short left
short top
short right
short bottom
short destination

Case studies

(Note: these are simply the data in (little-endian) shorts and line-broken where I saw patterns. <l t b r> are (I think) areas on-screen. count [entry]... are guesses at when there are lists of entries. The number in parentheses before the data is the card number (not the resource number).)
