Highlight the Mario Kart 8 Deluxe icon and press the + button.
The search plan is already provided. I'll start with the first round of searches to gather recent news, update history, and Title ID info. I'll search for "Mario Kart 8 Deluxe update 2025", "Mario Kart 8 Deluxe update 2026", "Mario Kart 8 Deluxe patch notes history", "Mario Kart 8 Deluxe version 3.0.3 patch notes", "Mario Kart 8 Deluxe Title ID 0100152000022800 update history", and "Mario Kart 8 Deluxe latest update version". first round of searches has provided several results. I have information about updates in 2025 and 2026, update history pages, patch notes for version 3.0.3, some Title ID references, and the latest version info. I need to open some of these pages to gather more details. I'll open the Nintendo update history page, the Perfectly-Nintendo page, the Nintendo Life article for version 3.0.3, the Gameblog.fr article, and the MarioWiki update history. I'll also open the search results for update 2026 to get more details from the Nintendo News article and the MarioWiki page. opened pages provide a lot of information. The Perfectly-Nintendo page has details on versions 3.0.5, 3.0.4, 3.0.3, etc. The Nintendo Life article confirms 3.0.3 fixed a netcode security flaw. The Gameblog article has details on version 3.0.4. The MarioWiki update history page shows a revision history. I need to get more details on the latest versions (3.0.4, 3.0.5) and also look for any information on version 3.0.6 or later. I'll search for "Mario Kart 8 Deluxe 3.0.6" and "Mario Kart 8 Deluxe 3.0.7". search for 3.0.6 didn't show a specific update. The GameRant article might be about version 3.0.4 or 3.0.5. I should open that to confirm. article confirms version 3.0.4. Now I need to gather more details on the Title ID 0100152000022800 . I'll search for that specific Title ID with "update" and "changelog". search results for the Title ID show references in homebrew tools, not official changelogs. This might be useful for context. Now I need to gather more information about the Booster Course Pass and major content updates. I'll search for "Mario Kart 8 Deluxe Booster Course Pass wave 6 update 3.0.0".'ll open the Wave 6 page and the patch notes for 3.0.0. I have a good amount of information on major updates. I should also look for information on update version 3.0.2 to fill in the gap.'s no specific 3.0.2 update; it seems 3.0.3 skipped 3.0.2. I should also look for information on version 2.4.0 and earlier. I'll open the MarioWiki update history page more thoroughly.'ll continue scrolling for more versions. I need to gather more details on the Title ID and its significance. I'll search for "0100152000022800 Mario Kart 8 Deluxe update history". search results mostly show homebrew tools. I should also look for any official Nintendo page that mentions the Title ID. But Title IDs are typically not used in official documentation. I'll use this information to explain what a Title ID is and how it relates to updates. UPDATE - Mario Kart 8 Deluxe -0100152000022800-...
