0Play a randomizer seed.
No console required.
Every item in A Link to the Past, shuffled somewhere else. Runs right here — no ROM, no emulator. A tribute to the late z3rsim.com.

New to this?
A check is anywhere an item can hide — 216 of them. A seed is one exact shuffle; the same seed always plays the same game, which is how races work. Change nothing, press Roll a seed & play, and open whatever is green.
Opened everything green and still stuck? 💡 Hint works out which of the places you can reach is holding the game up, names the area, and — if you ask twice — the exact spot. In Original travel it lights the door to walk through next.

How it works
- World map travel is the quick way in: click any check you can reach. Original screens is the real z3rsim — one room at a time, with real doors, small keys, crystal switches, mirror portals and the castle escape.
- Item pool, checks and logic follow the VT randomizer — the same rules the original simulator used. Dungeon prizes and medallions work as they do on console.
- alttpr.com seeds can be rolled or pasted in, and come with a permalink you can patch a real ROM from.
Fan project for practice & fun. Not affiliated with Nintendo or alttpr.com. Original Z3R Simulator by Kyong — z3rsim.com is gone; this recreates it from the ALTTPR-REFERENCE docs. Tinkerers: the room editor lets you fine-tune map spots, node positions and room art.
