I don't plan to speedrun this game, but I'm curious on the state of emulating the Wii version.

The dolphin wiki indicates that the game has no issues, but using any texture filtering features will cause FMVs to display incorrectly, as will setting internal resolution to auto.

Would Dolphin be permissible to play the Wii version?

The rules don't seem to mention anything on this, but it seems like every run is either on console or PC, as if emulator isn't allowed? Please clarify, not for me but for anyone else who wants to speedrun using an emulator.

I believe this was discussed in the past in our discord server. I believe it was found there are some physics differences so we decided to not allow it.

If it was really long ago, Dolphin might have improved since then, and the physics could have become identical because of those changes.

Test it out again if you're bored. idk
