About this Modpack

❤️ Welcome to the Jam Hardcore modpack — a collection crafted with love for Jam Hardcore server players, but perfectly suited for anyone who values a clean and enhanced Minecraft experience.

This modpack is built on Fabric and makes the game smoother, more beautiful, and more convenient, while fully preserving the vanilla atmosphere. It’s lightweight, runs great on low-end PCs, and requires no learning curve: everything feels familiar, just works, and looks better.

🎮 What’s inside?

🔧 Faster and More Stable
Mods like Sodium, Lithium, and Starlight handle performance and stability. They eliminate FPS drops and lighting issues without changing Minecraft’s visual style.

🌈 Better Visuals with Shaders
The modpack includes several built-in shaders that can be enabled in just a couple of clicks — no extra setup or downloads required.

📡 Voice Chat
PlasmoVoice adds in-game voice communication. It’s supported on servers with the mod installed, making multiplayer more lively and natural.

💃 Animations and Emotes
EmoteCraft lets you dance, strike poses, and even import custom animations from Blender. We’ve also included a ready-to-use SpEmotes pack, so there’s nothing to search for — everything works straight out of the box.

🏆 Achievements with Translations
The modpack includes BACAPED, a language pack for the BlazeandCave Advancements mod, translated into multiple languages. Over 1,000 achievements make world exploration and survival even more engaging.

Not Just for Jam Hardcore
While the modpack is primarily designed for our server, it works great in singleplayer and on other Fabric servers. It’s compatible with most Fabric mods, isn’t overloaded, and runs smoothly even on low-end machines.

Frequently Asked Questions

Jam Hardcore server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 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 Jam Hardcore server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 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 €8/month).

Can I add custom mods to Jam Hardcore without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (26.1.2). 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.

Jam Hardcore server lagging – performance tips

1) Increase RAM to 6 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.
