About this Modpack

Minecraft 12w02a

A while back, a Mojang employee posted what seemed to be a lost snapshot version of 1.1. Strangely, any attempts I made to reupload the .jar file failed, so this pack was made to recreate the version using assets pulled from the jar file.

There's something out there...

Modpack Details

DON'T CLICK UNLESS YOU'VE PLAYED THE PACK ALREADY! It's best if you go in without any prior knowledge of what it has, trust me.

SPOILERS

This pack pretty much completely reverts the game back to 1.1. This means no extra wood types other than Oak wood, early sounds, no new mobs, etc. While some modern minecraft stuff is still included (the Mace, ancient cities, etc.) most have been stripped back for the sake of accuracy. This also means skins & capes will NOT work. You will play as Steve and you will like it.

This pack also includes a bunch of QOL features I thought should've been in the game by now, such as little animations whenever you pick up items in the inventory, faster ladders, durability percentage tooltip, etc.

Also THIS IS A HORROR PACK. This pack attempts to creep you out as you play, through weird structures, events, and more. Be warned.

Frequently Asked Questions

12w02a server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong neoforge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a 12w02a server really need?

Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €12/month).

Can I add custom mods to 12w02a without conflicts?

Yes, but check compatibility: only use mods for the same loader (neoforge) and same Minecraft version (1.20.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

12w02a server lagging – performance tips

1) Increase RAM to 8 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
