King's Quest IV: The Perils of Rosella was the fourth game in the King's Quest series. The king of Daventry, King Graham, has suffered a heart attack, and is on the brink of death. The magical mirror of Daventry shows the king's daughter, Princess Rosella, a magical fruit in the distant land of Tamir that has powers to save her father's life. King's Quest IV takes place in a 24 hour period, where some puzzles can only be solved in day, where other puzzles can only be solved at night.

Installation

Required data files - SCI

For more information on how ScummVM uses game data files, see the user documentation.

WARNING: Unlike other games, SCI games have significant variation in the naming of required files.

They also can load supplementary files by resource maps, so it is recommended to keep all files in the game data directory from the CD.

Unless otherwise specified, do NOT remove any file from the directory, even if it does not appear on the following list, since this will likely cause weird bugs.

Copy all files to the game directory. Some games need additional work:

Floppy games with RESOURCE.p01, p02, etc. and/or RESOURCE.a01, a02, etc. files

• Concatenate all RESOURCE.p0* files to RESOURCE.000 (e.g. copy /b RESOURCE.p0* RESOURCE.000 on Windows, or cat RESOURCE.p0* > RESOURCE.000 on *nix).
• Concatenate all RESOURCE.a0* files to RESOURCE.AUD (e.g. copy /b RESOURCE.a0* RESOURCE.AUD on Windows, or cat RESOURCE.a0* > RESOURCE.AUD on *nix).

Required data files - AGI

All platforms

• *VOL.* (e.g. GRVOL.0, KQ4VOL.11, VOL.1)

Controls

Predictive input dialog

The Predictive Input Dialog is a ScummVM aid for running AGI engine games (which notoriously require command line input) on devices with limited keyboard support.

For more information, see the AGI/Predictive Dialog wiki page.
