There is no official PC version of Hatsune Miku: Project DIVA Mega Mix.

This game was developed and published by SEGA exclusively for the Nintendo Switch. Unlike Hatsune Miku: Project DIVA Mega39’s (which is the Japanese name for the same game) or previous entries like Project DIVA Future Tone (which is on PS4) and Project DIVA X (PS4/PS Vita), SEGA has not ported Mega Mix to Steam or Windows.

Therefore, any website claiming to offer a "direct PC download" or a "PC port" of Mega Mix is not legitimate. Downloading files from these sites poses a high risk of malware, viruses, or non-functional software.

Since the original MegaMix is a Switch game, some users attempt to download the ROM (cartridge dump) and run it via emulators like Yuzu or Ryujinx.
