Why Kaileron feels different
Arcade netplay that feels like everyone brought their own cabinet.
Every player runs the game locally while Kaileron keeps the shared session in sync. That means it is not screen sharing, not remote control, and not one player streaming a game for everyone else.
Rooms without a host PC
Players meet on a central lobby server, so a room does not depend on one player's machine being exposed as the host.
Spectators can catch up
Friends can jump into a match already in progress, sync up, and watch the action live without a separate video-streaming setup.
Replay the rounds worth keeping
Save memorable matches as compact Kaileron replays, then keep them, share them, or watch them again later.
Tunable for your setup
Choose automatic or manual input delay, and use local latency reduction options when your PC has the headroom.
A verified first launch
The launcher installs a pinned MAME runtime, verifies checksums, checks ROM requirements, and includes Alien Arena for a playable first install.
