Manic Miner 800 — play online

Loads the MZ-800 emulator (~7 MB) and runs the tape image. Sound needs a click — that's it.

Keys & tips

Click the screen to give it keyboard focus. Sharp specials: GRAPH = Caps Lock, ALPHA = \, INST = Insert, DEL = Backspace.
The emulator runs in kiosk mode: every key goes to the MZ except F11 (zoom: fullscreen on/off, Esc also leaves it) and F12 (restart the game) — same as the ⛶ Fullscreen and ↻ Restart buttons.
Phones/tablets: 🎮 Touch shows an on-screen pad (cursor keys, diagonals included), FIRE (Space) and RET (Enter) — enough for most games. Turn the phone sideways and use ⛶ Fullscreen.
Everything runs locally in your browser; nothing is uploaded.
