Ultima III Upgrade Patch

The Ultima III Upgrade Patch, created by Voyager Dragon, does many essential improvements to the MS-DOS port of Ultima III. Without the patch, the game would be unplayable on today's computers. The most current version of the patch is 3.3. The patch is intended to be installed in DosBox. The biggest changes of the patch are, that the graphics of the game get a complete overhaul, and that the game, which originally didn't sport any music in the DOS-port, now is fully scored..

Graphical Changes
The following graphics modes offers the patch:
 * Original CGA-graphic.
 * A CGA-composite tileset.
 * The original tileset upgraded to EGA 16 colors.
 * A VGA-tileset borrowing heavily from the Ultima IV Upgrade Patch.

Additional Changes
The following additional changes are made by the patch:
 * Enhanced MIDI Music from the C64 and Apple II versions, whereas the original MS-DOS port had no music at all.
 * The dungeons are also in color instead of being in monochrome.
 * Peer Gems yield a multi-colored look at the world map, versus only texture in the CGA, C64, and Apple II versions.
 * Restore (ALT-R), Exit (ALT-X), and Main Menu (ALT-M) hotkeys have been added to the game. ALT-X is also supported while at the Main Menu.
 * A Frame Limiter that eliminates the need for moslo.
 * Ability to Enable/Disable the AutoSave feature.
 * Replaces the 0-7 moon phases with actual moon icons.
 * Improved character creation, which eliminates the need to re-install the game for a new game session.

Changes to the Ruleset
In addition it offers a number of optional changes to the game's ruleset. These changes can either be toggled on or off together, not individually.
 * Double the overworld monster generation rate
 * Increase the dungeon monster generation rate inversely proportional to the dungeon level (2x on the first floor, only 25% more on the bottom floor)
 * Halve the food consumption rate

One problem used to be that the u3cfg.exe needs DPMI to work, which DosBox doesn't provide. The solution was to get a substitute here. In order to fix the problem, unpack the ZIP file and make sure that all the files are in the root directory of the game (no sub-folders). Starting with version 3.0, DPMI is no longer needed for everything to work as originally intended.
