About

Ultima IV: Quest of the Avatar, first released in 1985 for the Apple II, is the fourth Ultima role-playing game and the first in its "Age of Enlightenment" trilogy, notable for a much larger world and a shift toward an ethically driven, story-driven approach. Ultima IV Remastered is a remastered C64 port of Ultima IV, distributed as buildable source code rather than a standalone release — building it requires the player's own original Ultima IV C64 disk images, verified against known checksums. The code is licensed under Apache 2.0, with new graphics and a new crack-intro music track credited to separate authors, and no data from the original game included in the repository.

Getting started

Building it requires specific development tools (cc65, VICE's c1541 utility, exomizer, Python 2, and GNU Make) plus untouched original Ultima IV disk images placed in the source tree, after which running the top-level build produces the remastered game.

Requires original assets. Requires original untouched disk images of Ultima IV for C64 to build.

Media

Licensing & legal

The code, new graphics, and crack-intro music each carry separate author credit (Per Olofsson, Vanja Utne, and Johan Samuelson respectively).

Additional notes

Technical note: Track 6 of the original Program disk contains errors from its original copy protection, so the checksum of a rebuilt disk can vary depending on which tool created it.
