While (often referred to as by fans) was never officially released on PC, it remains a legendary title that fans frequently play on computers today via emulation. Because there is no official PC version, the "size" and system requirements depend entirely on which console version you are emulating (PS3, Xbox 360, or Wii). Storage Size Breakdown
If playing via an emulator like RPCS3 (PS3) or Xenia (Xbox 360), you should reserve at least 8–10 GB for the game files and additional cache. Estimated System Requirements (Emulation)
The raw game files typically range from 4.5 GB to 8 GB . For example, the PS3 version requires a mandatory 4.5 GB installation.
