I went through webarchive and found these old versions. These are not supported at all, but I'm putting them here in case anyone wants to play on an older version.
The earlier version were written by Verdana until version 1.7. For those versions, they were ported by Rene_Z and thatapplefreak. Any later versions (hosted on github) were ported by myself (killjoy1221).
Note: The 1.7 versions are mirrored from voxelmodpack.com
LiteMod - These require LiteLoader to run. They go in the mods folder.
Universal - These can be installed either by putting them in the minecraft jar or loaded by ModLoader in the mods folder.
Modloader - Loaded by Modloader in the mods folder. Probably works with Forge/FML, too.
Normal - These are installed by modifying the Minecraft jar.
