Ultima III Upgrade Patch

The Ultima III Upgrade Patch adds EGA 16-color, the complete musical score of the C64 version and other features to Ultima III. It also fixes several bugs of the original and adds new hotkeys (such as exit to DOS).

The patch can be downloaded from exodus.voyd.net.

One problem is, the the u2cfg.exe needs dpmi, which DosBox doesn't provide. You can find a substitute here. Unpack it and make sure that all the files are in the root directory of the game (no sub-folders). Now the u2cfg should work.
