SUPER C

This player runs the original game logic, so it needs your own copy of the game.
Drop your Super C (.nes) file here, or pick it:

Choose ROM file

Use a dump of a cartridge you own (North American Super C, iNES format, 256 KB, MMC3). Both online players must use the same dump.

The ROM stays in your browser (IndexedDB). It is never uploaded - not even to the other player.

Move Arrows / WASD   Jump Z / Space   Fire X / J   Turbo fire Hold V   Start Enter   Select Shift   Menu Esc
Gamepads work too. Online starts a fresh synchronized game after connection. The host chooses "2 PLAYERS" on that title screen (Shift, then Enter); joining does not attach to an existing solo game.
