I can certainly clarify the situation regarding "Beyblade Burst Battle Zero" for PC.

HEADLINE: The Lost Layer: Inside the Development of the Cancelled ‘Beyblade Burst Battle Zero PC’ Exclusive

Legality:

Players must legally dump their own game files from a physical Switch cartridge to use these emulators.

How to Play Beyblade on PC: The Options

Go to the official Citra website (citra-emu.org). Note: Since the Yuzu/Citra legal takedown by Nintendo, you will need to look for the "Citra Legacy" or community forks like "Lime3DS" or "PabloMK7’s Citra." This is legal to download as it is merely a tool.

  1. Citra Emulator (Canary Build): Citra is the only viable 3DS emulator. The "Canary" build handles Battle Zero better than the mainline version.
  2. The ROM: You must obtain a .3ds or .cia file of the game. (Note: We do not provide links. Search for the game’s title ID: 00040000001AF500).
