Is the Super Mario Galaxy PC port an emulator?

No. It's a native build of the game's code for PC (a decompilation, static recompilation or native port), so it runs like a PC game.

SUPER MARIO GALAXY RUNS ON A REAL PLAYSTATION 2 IN A NEW FAN PORT

Q: Is there a PC port of

Yes. Super Mario Galaxy on PlayStation 2: a fan port built from the Petari decompilation by danielnuld (built on SMGCommunity's Petari decomp). Source is available to build, and it runs natively on PC rather than through an emulator.

Q: Do I need my own copy of

Yes. Your own Super Mario Galaxy disc dump (USA, RMGE01 only). Windows 10/11 with WSL (Ubuntu), the ps2dev toolchain, Python 3.12+, ffmpeg and the other tools listed in the README. Plays on PCSX2 or a real PS2 that can boot homebrew. No game files are included.

Super Mario Galaxy on PlayStation 2: a fan port built from the Petari decompilation

danielnuld's smg-ps2 is a fan port of Super Mario Galaxy (Wii, 2007) to the PlayStation 2. The game logic comes from Petari, the community decompilation of Galaxy, running on a new engine written for the PS2's hardware, and the game's data is converted from your own disc by the repo's tools, so no Nintendo code or assets are shipped. The creator's README says it is playable from the title screen to the ending on PCSX2 and on a real PS2, with all 136 scenarios loading, about 96% of objects ported, Luigi, comets, memory card saves, rumble and the movies re-encoded for the PS2. It reports 60 fps in most places on PCSX2 but 26 to 58 fps on real hardware, with sound still being trimmed to fit. There's no release download yet: you build your own disc image. The repo went public on Oct 26; these are the creator's own claims and we haven't run it ourselves.
