 This repository is a clean slate for basic enhancements built upon the *Super Mario 64* decompilation. It is a spritual successor to CrashOveride95's *UltraSM64*.
 
+## Added Features
+
+ * Shifting segments.
+ * No 1 MB code limit for `src/game`.
+ * A full decompilation of libultra is included in `lib/hackerlibultra`.
+ * A Nintendo 64-specific libc implementation by falcobuster is provided in `lib/n64-libc`.
+ * Libdragon's IPL3 (`LIBDRAGON_IPL3=1`) provided as an optional Makefile configuration. See Makefile for details.
+
 ## Quick Start (for Ubuntu)
