    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.

    CDG Editor is a tool that allows the user to edit the contents of a CDG file (typically extracted from a karaoke disc as mp3+g). v1.3 now supports all CD+G command types. Please note that this is not a Karaoke creation or editing tools (see some of the comments below) - it is for fixing the CDG files that you have where the text is corrupt due to a poor rip from the original CD+G disk. You have to edit individual CD+G tile commands. This tool could be used to change the lyrics of a song for example, but it would be very difficult - that's not its purpose. Thanks for the feedback though. I've installed it on several Windows 7 64bit PCs but haven't tested the installer or the app on Windows 8 yet. Let me know via the support pages if you have problems and I'll see what I can do to help.
