Ultima IV Upgrade Patch

The Ultima IV Upgrade Patch is a fan-made upgrade to Ultima IV. The upgrade began as two parts: Aradindae Dragon’s Music Machine, and Wiltshire Dragon’s Graphics Package. The upgrade is a combination of their efforts. The latest version is 1.3, dated March 9th, 2001.

The patch includes the following upgrades:
 * It upgrades the graphics to 256 colors, replacing the tileset, font, game, and cutscene graphics. It also improves the graphical user interface.
 * It adds MIDI music support, and adds the original music from the Apple and Commodore versions of the game.
 * It corrects several conversation bugs within the original .TLK files.
 * It adds command keys to Reload the last saved game and Exit to the OS.

The patch can be downloaded from Auric's Ultima Moongates. DOSBox is one way to get the DOS sound drivers working properly.

Bugs
The upgrade has a bug that prevents it from working in Windows XP. Fortunately, there is a patched version. Downloading the patched avpatch.exe here and replacing the old one with it, fixes the problem.

Also under DOSBox, another bug makes the game die every time after character creation. The patch can only work if there is an actual avatar.exe to patch. Fixing this is simple: create an character and save, before patching the game. After that it should work fine.
