The game in 'King's Quest I VGA 4.2 2024\' 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.:

This is just the new version of KQ1VGA 4.2 RC1 English; doesn't run in Scummvm 2.9.0, just seems to be a newer iteration of AGS, I'm just reporting the new version cause ScummVM said to, and I usually do whatever it says lol. Thanks!

To give more info on the error of that ScummVM throws when attempting to run the game (after it's added in fallback mode).

For ScummVM 2.8.1 the error is:

Loading game failed with error:
Format version not supported.
Game was compiled with 3.6.136. Required format version: 3060114, supported 18 - 3060021.

The game files may be incomplete, corrupt or from unsupported version of AGS.

For ScummVM 2.9.0 (local dev build from today's master HEAD) the error is:

ERROR: Unable to determine game data. Provided game location is not a valid path.
Cwd: D:/Games/KingsQuestIVGA/
Path:

The game's RC is currently available from this thread on the agdinteractive forums:
​https://agdinteractive.com/forum/viewtopic.php?t=27004

Edit: The error in 2.9.0git now matches the one in 2.8.1 since the issue with the previous error has been fixed by commit: ​https://github.com/scummvm/scummvm/commit/8ab359cb0f760ff06dc9363f7f873ab54ac6752a

I added the detection entry in commit ​c4ecffe, however as you correctly stated the game uses a new version of AGS (3.6.1) and we only support games up to version 3.6.0.

There's an ongoing effort to update the engine, if you are interested you can follow progress ​here.
KQ1 4.2 is not playable yet, but most 3.6.1 games are working.

Moving to feature requests
