0.2.0 preview · 2026-10-16 · release notes

A native C port of Super Mario Land that loads every graphic, level and sound from your own ROM and plays back every tool-assisted speedrun frame-perfectly. Releases for Linux, Windows, the Steam Deck and PortMaster handhelds.

Warpzone brings its mod archive (levels, worlds, tilesets, skins, Lua behaviours), leaderboards for speedruns, and a shared-screen mode where up to 16 players each play their own game and watch everyone else's.

You need: your own Super Mario Land ROM — none is included or downloadable here

  • Speedrun timer (F8, or timer = yes under [speedrun]): Any% timing by the speedrun.com rules, from the frame before 1-1 appears to the frame Tatanga disappears, counted in exact Game Boy time. Splits happen on their own, one per level, with the difference to your personal best and gold best segments. category = normal+hard times Normal + Hard Mode.
  • Personal best, best segments and attempts are saved, with a LiveSplit copy (speedrun-any.lss in the data directory); --import-lss FILE takes over existing LiveSplit splits.
  • Installs managed by the Warpzone launcher are updated by the launcher instead.
