F-ZERO 99 has been updated to Ver. 1.1.5. You can see the patch notes for this update below.
Added Frozen Knight League, a limited-time Knight League where snow falls. All courses that are regularly included in the Knight League (MUTE CITY I, BIG BLUE, SAND OCEAN, DEATH WIND I, and SILENCE) will be blanketed in snow.
The Frozen Knight League event will be held for a limited time only. You can see how much time is remaining in the event by pressing the R Button on the main menu.
Regular Knight League tracks and Knight League Grand Prix cannot be played when the Frozen Knight League event is being held（except for training and practice modes).
Added Boost colors to be used for machine customization as well as backdrops, badges and borders to be used for Pilot Card customization. These can be unlocked when certain conditions are met.
The customization items added for this update can only be obtained during the time when the Frozen Knight League event is live.
You can check specified conditions and progress for each item by pressing the R Button on the main menu.
You can perform customization by selecting WORKSHOP on the main menu, and then selecting MACHINES and PILOT CARDS.
Fixed an issue that was occurring even after application of the Ver. 1.0.2 update where a specific badge could not be obtained even though conditions had been met. That save data will be fixed and the badge can now be obtained.
Fixed issues to make for a more pleasant gaming experience.
