BEHIND THE TOOT: Show more
I created a save file on the Majora debug ROM for this, then loaded it in the USA 1.0 version, enabled the map select with a Gameshark code, and used it to load the moon map (104). I don't actually have the boss remains you usually need to get there.
The rendering should be pretty accurate to N64 hardware, using Angrylion software RDP (rather than GL/D3D HLE). It runs at about half speed on my system, but my script renders the frames to a video file, so real-time performance doesn't matter.
