Zhelkas1 noticed a few spelling errors in the MS-DOS version of Ultima 1, most notably “Britain” being misspelled as “Britian”, and “Gweno” as “Gwino”. By making use of a hex editor to poke around some of the game’s EXE files, Zhelkas1 was able to correct these, with one notable limitation:

 I used a hex editor to make these fixes. It seems I am allowed to change existing strings but not add new ones, or the game won’t load properly. Therefore I can change the name to “Gweno” but not “Gwenno”.

To install the patch, make backups of MONDAIN.EXE, OUT.EXE, and SPACE.EXE, and then head on over to the patch’s project entry here at the Codex to grab a copy. Copy the files in the download into Ultima 1’s installation folder, and enjoy properly-spelled city and companion names.
