HAVE FUN!!!
NOTES:
- With the discontinuation of Play Game Services multiplayer, Multiness and Multiness GP are basically the same in term of functionalities now.
- Location permission is required for Wifi Direct multiplayer mode. Without it, 2nd player cannot find the 1st player who created the network game session.
- Voice Record permission is required for voice chat during multiplayer. You can disable voice chat in game if you don't want it.
- The app doesn't come with any games. You have to copy NES roms to your device's sdcard. Their locations will be detected automatically by the app itself. Both .zip and .nes files are accepted.
- When playing multiplayer, second player is not required to have the game roms in his/her devices, it is only required for the first player (i.e. the host).
- To reduce lag during multiplayer, place your devices as close as possible to each other and to the Router/Access Point.
- Alternatively, using Wifi Direct option if your device supports it.
- Playing over Internet consumes quite a lot of bandwidth which is roughly 60-100 KB per second.
- The one hosting the game through Internet is required to have the minimum upload speed around 60 KB/s (512 Kbps).
- If you encounter severe lags, sometimes a simple router or both players' device's wifi restart might help.
- There are some routers that don't support direct Internet multiplayer hosting due to their Firewall settings. If it is the case, the app will attempt to use relay server to relay data between 2 players, though the bandwidth will be limited if relay server is used by too many people. If relay server still fails, you will probably see "Remote connection timeout or disconnected" message popped up on guest player side. You can try to switch roles, i.e. guest becomes host and vice versa. If we are lucky, the new host's router will allow the connection between two players.
- This application is in no way endorsed by or affiliated with the original creators of NES hardware.
THE APP IS CURRENTLY STILL IN PREVIEW STATE, THUS WE WOULD BE GRATEFUL IF YOU COULD HELP US REPORTING BUGS TO lehoangq@gmail.com. THANK YOU.
