If you are running Atmosphere, SX OS, or Ryujinx/Yuzu (emulator), here is the step-by-step workflow for applying the -Update- file.
Let’s be real: The NBA 2K24 Switch XCI -Update- is a storage monster.
If you have a 128GB SD card, NBA 2K24 will consume roughly one third of your entire card by itself. Add The Legend of Zelda: Tears of the Kingdom (16GB) and Mortal Kombat 1 (24GB), and your card is full.
Pro Tip: Do not use a 64GB SD card for this game. You need a 256GB Sandisk Ultra or a 512GB Samsung Evo. For CFW users, you can install the base XCI to the SD card and "move" the update to the system NAND's internal memory (32GB) to potentially speed up loading times, as the Switch's internal memory is faster than most microSD cards.
This report provides an objective analysis of the Nintendo Switch version of NBA 2K24, specifically focusing on the distribution format known as XCI and the status of game updates. The report clarifies technical definitions, details the current version history, and outlines the performance improvements delivered through patches since the game's launch.
The Good: If you are a franchise (MyNBA) player, the update makes the loading screens between games roughly 15% faster. The core gameplay loop—shooting timing and defense—is identical to the PS4 version, which is respectable.
The Bad: The "ProPlay" animation system advertised for next-gen consoles is completely absent here. Players still move with the stiff "robot slide" of previous Switch 2K titles. Also, the Gatorade gym loading screen still takes roughly 45 seconds.
