Myst3 unknown game variant (error variant from ticket 13368)

[shepherdmoonllc]

The hash listed below for "RSRC.m3r" is different from the hash from defect 13368.

The error is:

The game in 'Myst III\' seems to be an unknown game variant.

Please report the following data to the ScummVM team at
https://bugs.scummvm.org/ along with the name of the game you tried to add
and its version, language, etc.:

Ticket #13368 refers to a variation of the 4-CD version, and you have a DVD version.

In fact, the hash value & size listed for the "RSRC.m3r" file is identical in both cases. The variation is in the "ENGLISH.m3t" file, which is to be expected.

This particular variant is already listed in the detection tables. I'd suggest trying a recent daily master build (2.7.0git) to see if your version is detected.

If it's detected, then it would appear the relevant commit may have missed the 2.6.0 release (as was the case with the 2.5.1 release).
If it's not, there may be a problem with how the Myst III detection code is being accessed.

Yes, you are correct about the hash difference. I stand corrected.

I've downloaded and installed 2.7.0git2328-gf3e2c3a074e (Aug 24 2022 15:42:49). The same error is generated as shown in the original description.

I've attached the "Pick the game" prompt that's shown when I use "Add Game" and navigate to the directory containing the Myst III distro. Maybe there's a clue in this.

For the DVD version, ScummVM expects the language.m3u of the chosen language to be placed in the M3Data folder and renamed properly (ENGLISH.m3u for english). See the wiki:
​https://wiki.scummvm.org/index.php?title=Myst_III:_Exile

In short, the file

<your game folder>\Myst III English\language.m3u

must be copied and renamed as

<your game folder>\M3Data\TEXT\ENGLISH.m3u

Add the game again and you should have the DVD/Windows/English entry.
