These are special mods that expand Minecraft beyond the 32bit integer limit. These 64bit and BigInteger mods let you teleport trillions of blocks away, visiting the native Java Edition farlands, and viewing where the farlands ended up after they got "patched" in beta 1.8. Currently there are only two BigInteger mods, for Java Edition inf-20100630-1 and 1.3.2. Both are currently unsupported, however the 1.3.2 version is a lot less bug free.

Note from Zeta: This mods is in ALPHA and is likely very buggy. I don't even recall if I ever added proper 64bit worldgen to this mod but I'm uploading it regardless. This mod is also unsupported, as in it won't get any bugfixes for the time being.
Note from Zeta: Some of these files were solely uploaded in a Discord server that no longer has any affiliation to Cursed Creations Inc. If you have any of these missing versions, please send them in the new official Discord server for us to upload them, as I kinda forgot to backup these files and lost the source code.
