Ultima IV: Quest of the Avatar is a singleplayer RPG game in the Ultima series.

While the original Apple II version had music through sound card support and most other versions played music using their native sound hardware, the unpatched DOS version does not have any music.

The unpatched game has issues on faster systems; use the upgrade patch to fix this.

  1. 1.0 1.1 File/folder structure within the installation folder reflects the path(s) listed for DOS game data. For the release, file changes in DOSBox are redirected to <path-to-game>/cloud_saves/ even if GOG Galaxy is not used (this folder contains all redirected files, so some files in the cloud_saves folder might be temporary files or other files that do not contain saves or settings).
