MultiSneS16 is an Android app developed by HQgame that allows users to play classic games with their friends via LAN network or online. This app is a variant of the Snes9x open-source emulator and supports hassle-free online multiplayer without any manual setup or opening network ports. 

MultiSneS16 offers offline single-player mode, LAN, Wifi Direct, and online multiplayer modes. It also supports long-distance connections, but the gameplay quality will depend on the network connection's speed. Additionally, users can invite others to play online using a social network account or join public servers created by other users. 

MultiSneS16 supports text chat during multiplayer, saves and loads game states even when playing multiplayer (on host side only), cheats, hardware controllers, virtual/on-screen/touch-based controllers, and editable virtual buttons' layout. The emulator is powered by the open-source Snes9x core. MultiSneS16 is a completely non-commercial app without any ads inside it.
