MCP Decompile Error

Discussion in 'Programming' started by Pwnda, May 4, 2021.

  1. I'm trying to make a Minecraft client. But getting this problem. It says its some error in decompiling.

    People says it needs more ram but then that leads to many more errors. Please help

  2. Buildtools is open source, maybe check how md_5 is doing it and get inspired by it.
