About this Modpack

ReAlpha

A modern Fabric recreation of Minecraft Alpha v1.0.4, rebuilt for Minecraft 1.21.

Rather than a simple downgrade or snapshot clone, this modpack is a near 1:1 remaster using modern Fabric mods, configs, and resource packs to accurately reproduce the feel, mechanics, and atmosphere of Alpha Minecraft while benefiting from modern blocks & items, performance and stability. The experience is intentionally kept as close to the original as possible

How to Set Up a ReAlpha Server

Order Server

Choose at least 4 GB RAM (6 GB recommended for ReAlpha). Based on player count: per 8 players.

Install Modpack in Dashboard

Open the modpack browser in the dashboard, search for "ReAlpha" and click "Install". The fabric loader and Minecraft 1.21.1 are configured automatically.

Start Server & Play

Start the server – all mods are loaded automatically. Share the server IP with friends and play together!

Frequently Asked Questions

ReAlpha 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 ReAlpha 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 ReAlpha without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.1). 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.

ReAlpha 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. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
