Is There a Cheat to Unlock All Doors in Super Mario Bros. X?

No official cheat code exists to unlock all doors in Super Mario Bros. X (SMBX).

Why

• Custom Engine: SMBX is a fan-made Mario engine (by Redigit), not a Nintendo ROM hack. It has no built-in cheat console.
• Level-Specific: "Doors" are level-design elements; unlocking them depends on the specific episode/level pack you are playing.

Workarounds (Advanced)

• LunaLua Scripting: Modern SMBX versions (SMBX2, 38A) support Lua scripts that can manipulate game state, but this requires coding knowledge.
• Level Editor: Open the level in the editor and remove/change door requirements manually.
• Save Editors: Community tools may edit save files, but compatibility varies.

Warning: Modifying game files can corrupt saves. Always back up first.
