Mods for a map made on every day of the year. What that means is that there will be a mod for a Minecraft map that was made on January 1st, then a mod for a map made on January 2nd, and so on. Each mod will have its own "mini-post", which are the spoilers down below. More information will be added when there is more information in the first place.
If you're having trouble finding a specific day/mod, use Ctrl+F (I think Command+F on Mac) to find the post, it should be there, or around that area because the dates are based off of Central Time.
Jan 1 - The Legend of Lunos Part 1: The Journey | Beta 1.1_02
This mod is pretty empty, because I don't know how to make entities in Minecraft, especially with such an ancient version, so there is just one block.
I might add entities later, but don't get your hopes up.
Iron Bars: Just the iron bars from Beta 1.8, but are a full block because I don't know how to make them not a full block. They even have the same texture from Beta 1.8. There are some issues with being able to see through blocks because of the transparent texture, which can be useful to find caves, I guess.
Crafted with 4 sticks in a 2x2 square (I accidentally compiled the mod with the placeholder recipe.)
To install, I would recommend MultiMC. With MultiMC, just click "Add to Minecraft.jar" in MultiMC on Beta 1.1_02, then find the downloaded .zip file on your computer, select it and hit "OK". For other launchers, look up some tutorials, and if you are using the official launcher, make sure to add something along the lines of "old mods with the new launcher". There's a .json file for this scenario in the .zip for the mod, so remember to make use of that.
