1.6.1 has been applied to waterworld New launcher is required. I am also saddened by the loss of PPC support for minecraft.
nibiru will be updated to 1.6.x as soon as a stable build is available.
hope to see you guys and your trusty steeds soon
edit: new launcher makes it much easier to have multiple versions running
