There is no official PC port of Budokai Tenkaichi 3. The game was released exclusively for PlayStation 2, Wii, and (a downgraded version) for PSP. The "Tenkaichi 3 PC" experience refers to emulation (primarily using PCSX2 for PS2 or Dolphin for Wii) or fan-made mods (like Budokai Tenkaichi 4 mod for the PC).
