+
+[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.
