v1.2 — Worlds, Memory & Integrity

v1.2 — Worlds, Memory & Integrity

Added

• Local Worlds browser: lists your singleplayer saves (parsed
  directly from level.dat, no extra dependencies) with the version
  each world was last played on. Selecting a world automatically
  switches the launcher to that version to prevent save corruption,
  and shows when each world was last played ("2h ago", "5d ago", etc.).
• Configurable memory allocation: set how much RAM Minecraft can
  use (1-8 GB) directly from the menu, with built-in guidance for
  Vanilla, modded, and heavy modpack setups. No more hardcoded 2GB cap.
• Download integrity checks: client, libraries, and assets are now
  verified against their official SHA1 checksums during download.
  Corrupted/incomplete downloads are automatically discarded and
  retried on the next launch instead of causing mysterious crashes.
• Clearer feedback after launching: mcTUI now tells you explicitly
  that Minecraft keeps running in the background after the terminal
  closes, or shows the last lines of the crash log if it exits early.

Notes

• World detection and last-played times use a minimal, dependency-free
  NBT parser built specifically for this purpose.
