a hostel at Castle Britannia, requiring the player to return there to change characters. However, the combat system was fairly close to the personal computer games, with the additional option to use automated combat. Additionally the spell-casting was simplified, removing the need to mix spells. Some puzzles were removed as well. This port also replaced the character Julia the Tinker with a male character named Julius. Some of these changes were done because of the memory limitations of being on a single cartridge instead of multiple floppy diskettes. Master System Ultima IV: Quest of the Avatar for the Master System is the only Ultima to be ported to a Sega platform. It was released in 1990 and was both ported and published by Sega. The port features completely re-drawn graphics (although unlike the NES port, the style was retained from Origin's version), a simpler conversation system and, unlike the NES version, uses the regular Ultima IV background music. Although the Master System is easily capable of displaying more complex first-person scenes than those found in Ultima IV (see Phantasy Star), this version's dungeons are viewed from a top-down perspective, much like those of Ultima VI, which was released the same year. It seems that most of these cartridges were produced for the European market, as they contain a multi-lingual (English, French and German) manual, both books from the original version as well as a folded paper map. The books were of different colour for each of the three editions (blue for the UK version), fully translated and did not fit inside the game's box. There is a graphical error in this version where the gypsy's picture is of a man with a mustache even though the gypsy is referred to as "she" throughout the text. Ultima IV on modern operating systems xu4 is a cross-platform game engine recreation of Ultima IV under development for Dreamcast, Linux, Mac OS X, RISC OS and Windows. Two other remakes were using the Neverwinter Nights engine. An online version was written in Adobe Flash. In March 2011, Electronic Arts sent a DMCA "cease and desist" notice to this fan project. In 2015 also a fan-made remaster project for the Commodore 64 version of the game was released with source code on GitHub, addressing bugs and improving other aspects of the game. DOS version of Ultima IV is available for free through GOG.com. Publisher and
