U4DosRandomizer

Randomizer for Ultima IV Currently this randomizer randomizes the over world map and deals with all the repercussions of the overworld map being randomized.

Requires Ultima IV which is available for free at https://www.gog.com/game/ultima_4.

1. Download the randomizer from https://github.com/Fenyx4/U4DosRandomizer/releases.
2. Unzip and drop the executable in the Ultima IV directory (same folder as the WORLD.MAP file).
3. Backup your original game. This has an option to restore but don't trust it we're still in alpha.
4. Run the executable.

Options:
  -s |--s <seed>             The seed for the randomizer.  Same seed will produce the same map. Defaults to random value.
  -p |--p <path>             Path to Ultima 4 installation.  Leaving blank will assume it is the working directory.

If you end up making changes to the game's source code you will need to update the diff files. Run U4DosRandomizer.Patcher with the below parameters then copy the diffs into U4DosRandomizer/patches and rebuild. -b "E:\Projects\U4DosRandomizer\u4_decompile\SRC\ORIGINAL\AVATAR.EXE" -s "E:\Projects\U4DosRandomizer\u4_decompile\SRC\ORIGINAL\AVATAR.EXE.sig" -n "E:\Projects\U4DosRandomizer\u4_decompile\SRC\ORIGINAL\U4_MAIN.EXE" -d "E:\Projects\U4DosRandomizer\u4_decompile\SRC\ORIGINAL\AVATAR.EXE.octodiff" -b "E:\Projects\U4DosRandomizer\u4_decompile\SRC-TITLE\ORIGINAL\TITLE.EXE.orig" -s "E:\Projects\U4DosRandomizer\u4_decompile\SRC-TITLE\ORIGINAL\TITLE.EXE.sig" -n "E:\Projects\U4DosRandomizer\u4_decompile\SRC-TITLE\ORIGINAL\TITLE_0.EXE" -d "E:\Projects\U4DosRandomizer\u4_decompile\SRC-TITLE\ORIGINAL\TITLE.EXE.octodiff"
