This is a Nintendo emulator I wrote in C# in November-December 2006. It is very incomplete. Controls work. Sound is not working. Scrolling is not supported right now. Almost all games that don't use a mapper load and show their demo or title screen at least. Several are somewhat playable.
This was mainly a learning experience for me. I had never written an emulator before, never written a game before, and I had never worked with assembly code before.
