The only requirement to use the program is to have Minecraft already installed on your PC. If you have done so (something fairly logical if you want to use MCPatcher), you just have to specify the file you want to work with (the Minecraft .Jar) and you're ready.
From the interface, you can easily manage those changes or texture packs you wish to apply and those you do not. And better yet, you can launch the game directly from the application to instantly check the results.
MCPatcher has many more features and capabilities, such as an integrated texture package converter for newer versions of Minecraft. And thanks to the tutorial, which can be found in the author's forum, you can master the vast majority of them in five minutes.
MCPatcher is a management tool for Minecraft that will help players get the most out of one of the most groundbreaking independent games in recent years.
