Today we've finally released a new Mario Kart Wii update on Wiimmfi (through the automatic patcher system) that contains a couple of the code changes that have been added to CTGP recently. As we can auto-update the game, all you need to do to get this update is to reboot your console and connect to Wiimmfi through Mario Kart Wii.

Here's a small list of changes since the last update some time in 2021:

• When losing the connection to the Wiimmfi server (due to an unstable internet connection, Wiimmfi issues, maintenance, ...), the game will automatically switch to a LAN-like mode - your active race / match will continue as usual, without the server, and in the background the game continously tries to reconnect to Wiimmfi.
  Of course, this means that while you're not connected to Wiimmfi the statistics pages (showing your driver/vehicle, track, ...) might not always update properly; and if the host disconnects from Wiimmfi mid-race, it can take a race or two for the statistics page to "figure out what happened" until the room shows up properly again (maybe you've already seen this in action with CTGP). But that's still better than everyone disconnecting. Also, while the host of a match is not connected to Wiimmfi, nobody will be able to join the room until the host has reconnected to Wiimmfi or left the match.
  During the race, there's no indication if you're currently connected to Wiimmfi or not. On the voting screen, the text at the bottom will be replaced by "Connecting to Wiimmfi ..." if you're currently not connected to the server and the game tries to re-establish the connection.
  Unfortunately, this reconnect thing only works when you lose the connection to Wiimmfi, not when you lose the connection to the host or to another player. Who knows, maybe that'll come some time in the future to make the game really resilient against connection issues.
  
• Mario Kart Wii had a bug where online opponents could rarely get stuck out-of-bounds when going over a halfpipe. This bug is now fixed and opponents will teleport back onto the track after a couple seconds if this happens.
  
• Players hosting a match / room could sometimes get error 86420 mid-race, if another player with a crappy internet connection tried to join, which was fairly annoying. Now this only occurs if multiple people fail to join the match, as that usually indicates a NATNEG issue with the host; and not just if one single person failed to join (which usually indicates a NATNEG issue with the joining player).
  
• The old frameskip code that could only switch between 60 and 30fps has been removed and replaced with a dynamic frameskip code. Now, if the game begins to slow down for whatever reason, the game can switch to 30fps, 20fps, or 15fps depending on the amount of lag involved (or even lower to 12, 10, 8.57 or 7.5 fps, but you're not going to see these in normal matches ever). I imagine this is going to be more useful for CT packs than for the base game, as custom tracks are usually more likely to cause lag than Nintendo tracks.
  This frameskip mode currently doesn't work properly on Dolphin, but I'm hoping to be able to fix that some time so that in the future stuff like a 30FPS code would be unnecessary.
  
• Artificial online lag (your console lagging because of another player's actions, which sometimes happened on broken Custom Tracks) is gone.
  
• When using Dolphin, closing Dolphin while in online mode, then opening Dolphin again, starting MKWii again and trying to get online did sometimes cause error 67010 (due to port conflicts) which was annoying to get rid of. This is now fixed by making the game pick another random port if its actual game port is not available.
  

Huge thanks to MrBean who wrote most of the code for these features while I did a whoooole lot of testing and suggested a couple bugfixes; and thanks to Wiimm for implementing all the server code for the reconnect feature.

The reconnect code has been included in CTGP for a while (6 weeks, I believe) so I don't think people will find major issues with this update; but I wanted to make a dedicated thread for this anyways instead of having it buried in one of the generic "Wiimmfi server" threads, just in case there is feedback or general issues with this update in particular.

I will probably close / lock this thread at some point in the future to prevent it from becoming a general Wiimmfi discussion thread.
