NocturneRecomp

What you need: The Xbox Live Arcade package of Castlevania: Symphony of the Night, dumped from your own console, with or without its title update.

NocturneRecomp is a native port of the Xbox Live Arcade version of Castlevania: Symphony of the Night for Windows and Linux (x64 and ARM64), made by static recompilation with the ReXGlue SDK.

The recompiled game is wrapped in a small host runtime with logging, overlays and hooks, so it can be modded like a PC game. There are separate builds for the game with and without its title update, and recent releases add a native achievements screen and Japanese text.

The download contains no game data. It needs the Xbox Live Arcade package of Castlevania: Symphony of the Night, dumped from your own console.

How to set it up

1. Download the build for your system; the builds marked TU are for a game with the title update installed, the others for the game without it.
2. Extract the archive and run nocturnerecomp (nocturnerecomp.exe on Windows).
3. The first run asks for your XBLA package and extracts the game from it.
