The 4GB Patch (also known as Large Address Aware patch) is a tiny but essential utility that modifies 32-bit Windows executables to use up to 4 GB of virtual memory instead of the default 2 GB limit. For Ultima Online, this is particularly useful when loading large custom maps, high-resolution textures, or running heavily modified clients that would otherwise crash with out-of-memory errors. Simply run the patch on your client.exe to enable the expanded memory space. Works on any 32-bit PE executable.

Client Auto Update 0.87 is a patching and auto-update system for UO freeshard clients. It allows shard operators to distribute client file updates to their players automatically. When players launch the updater, it connects to the shard’s patch server, checks for new files, and downloads only the changed content. Simplifies the process of pushing custom art, map changes, or configuration updates to the player base.

Cliloc Editor 2 is a tool for editing Ultima Online’s cliloc (Client Localization) files. These files contain all the text strings displayed in the UO client — item names, system messages, skill descriptions, spell names, and more. Shard developers use this editor to customize text for localized or custom content servers. The editor allows searching, editing, adding, and removing text entries by their numeric cliloc ID. Essential for any shard that needs custom item names or translated content.

Razor is the most widely used assistant program for Ultima Online. It provides essential quality-of-life features including macro recording and playback, hotkeys, auto-healing, dress/undress agents, organizer agents, vendor buy/sell agents, counter bars, and overhead messages.
