+[Nestadia][nestadia] by [@zer0x64], [@junior-n30] and [@CBenoit]
+is a server-based NES emulator.  
+
+Nestadia was written as a reverse engineering and memory exploitation challenge
+for NorthSec CTF 2021, a cybersecurity competition. Contestants were required
+to reverse-engineer the emulator and ultimately write a Tool Assisted Speedrun to run 
+arbitrary code inside a provided ROM.  
+
+After the competition, the code was open-sourced and 
+cleaned up to remove references to the competition.
+The developers intend on fixing more bugsand adding more features in the near future.  
+
+Some interesting features of this emulator are its server-based nature,
+and the no_std core which means that the emulator can be built and 
+ran pretty much anywhere without much work.
+
+Incoming improvements include online multiplayer,
+sound, a WASM port, porting to a libretro core,
+and using wgpu instead of sdl for the native GUI and debugger.
