Zero Tolerance Controls — Mega Drive Keyboard Keys

Default keyboard bindings for Zero Tolerance on our in-browser Mega Drive emulator. Plug in a USB or Bluetooth gamepad to auto-detect mappings, or rebind any key from the emulator settings menu.

Keyboard Console button Typical use
D-Pad Up Move up
D-Pad Down Move down
D-Pad Left Move left
D-Pad Right Move right
X A Primary action (jump / confirm)
Z B Secondary action (attack / cancel)
S C Tertiary action
A X Quaternary action
Q Y Fifth button
W Z Sixth button
Enter Start Start / Pause

These bindings cover the 6-button Mega Drive controller. Most older titles only use buttons A/B/C; the extra X/Y/Z buttons matter for Street Fighter II and other 6-button fighters.

Rebind any key from the EmulatorJS in-game settings menu (gear icon → Controls). A connected gamepad auto-maps to the same buttons.
