Data Hack: ModloaderMP for Minecraft 1.1

ModloaderMp is another kind of mod that is like Modloader. It is required for some mods to run properly, but the ironic thing is ModloaderMp requires Modloader to run, so you need both modloader and modloadermp.
ModloaderMp was originally created by SDK but he stopped upgrading it since 1.7 so Flan has made his ‘unofficial’ up to date copies since 1.8.

Not many mods require modloadermp but almost all server mods (yes mods, not plugins) require this. And no, the server modloadermp is not the same as the normal modloadermp.
