# Nebula: bringing Super Mario Galaxy to Windows

> Nebula runs Super Mario Galaxy on 64-bit Windows. Release 1.0.2 plays the North American disc RMGE01 from start to finish. Setup translates that disc's PowerPC code to C++ and compiles it locally. The current branch, Nebula 2, is unreleased and builds the game from the Petari decompilation, adding the European disc RMGP01 and the Japanese disc RMGJ01. Windows 10 version 1803 or Windows 11, a Direct3D 12 GPU, and 8 GB of RAM are required. Source steps are in docs/BUILDING.md.
