Is there a PC port of

Yes. Sonic Adventure gets a complete matching decompilation, the first for a retail Dreamcast game by reshaped. Source is available to build, and it runs natively on PC rather than through an emulator.

Is the Sonic Adventure 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.

SONIC ADVENTURE IS 100% DECOMPILED: FIRST COMPLETE MATCHING DECOMP OF A DREAMCAST GAME

Q: Do I need my own copy of

Yes. A Linux x86-64 PC with make, Python 3.8+, a C compiler and curl, plus your own Japanese Sonic Adventure disc (HDR-0001, v1.007) for a full build. 'make check' runs without the disc. No game files are included. This builds the original Dreamcast binaries; it is not a playable PC port.

Sonic Adventure gets a complete matching decompilation, the first for a retail Dreamcast game

reshaped has published a complete matching decompilation of the original Japanese release of Sonic Adventure (HDR-0001, version 1.007), which the README calls the first complete matching decompilation of a retail Dreamcast game, including the Katana SDK code it links. All 247 binaries (the main executable plus 246 overlays for stages, bosses, fields, Chao gardens, menus and 204 story events, about 5.8 MB of code) rebuild from source byte for byte; 97.7% is C and the rest assembly, much of it handwritten in the original. It is a source-code milestone, not a PC port: building it checks every rebuilt binary against your own disc, using period Hitachi SHC compilers from the decomp.me archive. A matching decomp is the base that native ports and deep mods are usually built on. It is separate from the Sonic Adventure recompilation work already on the wire.
