Dependencies and Compatibility

Required Runtime Dependencies​

BetterRailwaySystem currently expects:

  • Minecraft 1.21.1
  • Fabric Loader
  • Fabric API
  • Cloth Config
  • Java 21+
  • ModMenu (client only)

Limited Situation​

If the client joins a server that does not run BetterRailwaySystem:

  • line-map requests are disabled
  • server asset upload and sync are disabled
  • other server-backed operations are gated off instead of trying to run incorrectly
