As noted here, some later Sierra games have SCI resources, but are very different internally to the original SCI engine and thus are not supported:

This includes Shivers 2 and the two games starting with Betrayal.

Quoting the code:

Shivers 2 doesn't contain SCI scripts. The whole game logic has
been reimplemented from SCI in native code placed in DLL files.
Each room has its own DLL file, and some SCI functions have been
reimplemented/rewritten for this purpose in native code. The
game and demo have all the resources of a SCI game, apart from
the SCI scripts themselves. Thus, they cannot be directly
supported, unless their whole room logic is rewritten from
scratch, which classifies Shivers 2 as "not SCI"

So these games will not be supported by the current SCI engine and the work to implement these would be extensive.

Will list this as "Won't Fix", but this bug should fix the detection to avoid flagging this as a supported game.

I see, thank you very much for reply! I didnt realy had my hopes high, but decided to try. Looks like there is no emulator that could launch "Betrayal in Antara". It is a real pity, this game is my most favorite from old times.

Resolution: invalid
Status: newclosed

Closing as invalid since this is a story of adding an unsupported game that has the same generic filenames as other SCI32 games, causing autodetector to suggest a different game. That the suggested game happened to be Shivers 2 confused the issue -- we deliberately have that as an entry with the ADGF_UNSUPPORTED flag set. (Work was started long ago to add support.) But even without the Shivers 2 detection entry, auto detector just would have suggested a different SCI32 game with the same generic filenames.

If bluegr wants to we can remove the Shivers 2 detection entry if it's indeed not helping anything.
