Hello KOF Fans!

We have been working with Code Mystics in the weeks following this release to improve the gameplay experience for all of our fans, and now that we have squashed most of the small bugs and double-checked that everything is working as intended we wanted to give a quick breakdown on two of most important additions to the game!

Rollback Netcode

One of the first major improvements to the game was made shortly after release with Code Mystics implementing a new type of rollback netcode into the game. We have been monitoring feedback and bug reports to make sure it is stable and are now confident that it is working as we hoped. This new netcode option should improve the online experience for a lot of players. We also put together a quick guide on what this means for the experience and how it is implemented in this game specifically:

What is Rollback?

When you have a connection with high ping, under older netcode, your inputs would be delayed until your opponent's inputs for that same frame are received. With Rollback, your inputs can be accepted instantaneously, without waiting for your opponent's inputs to arrive. When your opponent's actions do arrive, their character will sync with the action they had earlier set in progress. (With Rollback, you may not see the first few frames of an opponent's new action, because it will already be in-progress by the time it reaches you. These skipped frames are called Rollback Frames or "teleporting".)

How to Use Rollback:

On the Room screen, prior to entering your match, you will see a white bar graph showing how many frames of delay to expect because of your connection's ping. You can then choose how many of those frames you wish to allocate to Input Delay vs. Rollback. Move the marker to the right for more Input Delay for your character and less Rollback Frames (teleporting) for your opponent. Move the bar left for less Input Delay for your character and more Rollback Frames for your opponent.

You may also choose what to do if the connection becomes better than the number of Input Delay frames you have allowed. If you set the "Min Input Delay" option to "Variable", the Input Delay will become less than your setting if the connection gets better. If you set "Min Input Delay" to "Fixed", the Input Delay will stay at the value you set even if the connection gets better. You may wish to use the "Fixed" setting to ensure that you get a predictable number of Input Delay frames regardless of what kind of connection you have.

Note: each time you enter a new Room, it will reset to the default Rollback options that you set in "System Options" under the "Min Input Delay" and "Max Input Delay" settings. Use the "System Options" menu to change these defaults.

Chinese UI Localization

We noticed there were a number of requests for Chinese language localization as well, so we worked with Code Mystics to have this implemented in this latest build. Please note that this only covers the new front-end UI made for this release. The in-game language will still only support English, Japanese, Portuguese, or Spanish as those are the only languages in the AES ROM.

There have been a variety of other bug fixes over the last few weeks as well, and we will continue to work with Code Mystics to improve the experience.
We appreciate everyone's support and patience, and hope that you will continue to work with us to improve the experience going forward.
