New Frontier CraftWebsite: http://newfrontiercraft.net/
New Frontier Craft is a mod being developed for Beta 1.7.3, starting on the 27th of April in 2014 and continuing to today. This mod adds in a multitude of new ores, reformats the tool tier system, and overall adds and tweaks a lot of the in-game mechanics.
Versions of NFC 1.8.5 and beyond require additional libraries to be initialized with them in order to work (those being authlib 1.5.24, gson 2.2.4, log4j-api 2.0 beta9, log4j-core2.0 beta9, commons-lang3 3.1, commons-codec 1.9, commons-io 2.4, and guava 15.0). For that reason, it's recommended you use the MultiMC instances from the official website for installing those versions rather than trying to set them up manually.
