Several years ago, Nytegard undertook a project to crack into the data files for Ultima 5, and proceeded to extensively reverse-engineer the game. Along the way, he built himself several tools to assist in decoding elements of the game’s data, most notably its graphics and conversation files.

Nodling Dragon made his source code available for download, and I have added this entry — with the same files — to Aiera to serve as a second mirror for Nytegard’s work. All of the above downloads are source code archives, and must be compiled with (at minimum) Microsoft Visual C++ 6.0 and the DirectX SDK.

* Ultima 1, 3, 4 & 5 Cheat (19.2 KiB, 712 hits)

A cheat program that can be used for Ultima 1 through to Ultima 5 (but not, according to its name, for Ultima 2).

Note: this update may not work with Ultima 3, and may also be missing the strength attribute. This has been found to be the case in DOSBox, at any rate, although at present it is not known whether the error is within the program proper, or whether it is in some way related to DOSbox.

Another utility from Xenerkes Dragon, this program allows you to edit your savegames from Ultima 1 through to Ultima 5. It allows you to change everything, including character location, and also makes it possible to get horses and boats in Ultima 3 (which is otherwise more than difficult).
