    MisakaTranslator

    MisakaTranslator

    Galgame's Multilingual Real-time Machine Translation Tool

    MisakaProject is a collection of all projects developed based on MisakaTranslator or its auxiliary functions.

MisakaPatcher added support for plug-in Chinese patch, so this tool is more suitable for players who like manual translation, and also provides another way for Chinese personnel who have difficulty unpacking packets to release Chinese patch. MisakaHookFinder is suitable for some games where the translator can not be used to directly get the text hook method. Users can search for the hook special code by themselves or directly use it to get the source text. At the same time, it also supports the clipboard to output the original text.

    Depressurizer

    Depressurizer

    A Steam library categorizing tool

    Depressurizer is a program aimed at making it a bit easier to manage large Steam game libraries. It can auto-categorize your games for you. Currently, it does so based on data from that game's Steam store pages. It can use genres, Steam flags (like "Single-Player" and "Steam Cloud"), Steam tags, Developer & Publisher info, How Long to Beat times, year, and/or Steam review user scores. Auto-categorizing can be done manually or automatically via shortcuts. In addition to providing a way to quickly and easily modify games' assigned categories, it also lets you mark them as favorites or as hidden. It also saves your configuration information independently of Steam, providing an automatic backup in the event that Steam loses your configuration. It must be run on the same computer on which you use Steam or one of the computers on which you use Steam. The first time you run Depressurizer, it will ask you for your Steam directory.
