Myst RLST resources

These seem to contain Myst's hotspot data.

There are the same number of RLST and VIEW resources in all Myst packages and we suspect RLST resources are associated to their cards by sharing the ID with the corresponding VIEW, similarly to what happens in Riven with CARDs and HSPTs.

• 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)

clone2727 says: This does not seem to match everything. I don't think the second short represents type.

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).)

Intro Case Study

See a bit below for where the game starts, INTRO 0. Here's INTRO 1, because it's more deciphered than that.

(INTRO 1) 1
5 2 <245 202 304 253> 4 2 37 0 0 34 0 2 3 11

INTRO 1 is the first interactive part of the game, the part where you can pick up the Myst book. The rect correctly corresponds to where the book is on screen. But, look at the "destination" -- 4. There is no VIEW/RLST 4! However, there is a WDIB 4 and it is the open book with the water. Where this should go is to card 3 and show the Myst book cover before showing image 4 and then playing the video. And, there is a 3 in this chunk, but I'm not sure if that's the purpose. I have no idea what the 37/34 could mean. There is a WDIB 11, but it's of D'ni, so I doubt it's that. ;)

(INTRO 2) 2
0 2 -32000 -32000 32000 32000 5
6 0 <312 70 441 159> "\qtw\intro\intro2" 0x2848 0x2756 0 1 0 0 0

Note that this one has a string for the video (null-terminated). This obviously calls that video which is the Myst fly-by for the linking book. And, that rect perfectly matches where the video should be displayed on screen. However, this also clearly breaks the format specified above for "type 2 hotspots".

WDIB 3 is the cover of the Myst linking book. But, this doesn't match up with the video mentioned here which should be for WDIB 4 (or 10, they are identical)(the open linking book with the water image) and eventually ending at WDIB 12 (the open linking book with the dock image). The 5 after the very large numbers is the target card for the open linking book which seems correct. 0x2848 is 10,312 and 0x2756 is 10,070. The rate of the audio is 11,025. Not sure if this has any correlation.

(INTRO 0) 1
0 2 -32000 -32000 32000 32000 5

This is the same as the first record of INTRO 2. My guess is that this is some sort of call to an external command. INTRO 0 is supposed to be the card which shows the opening movies and then switches to card 2.
