NESICIDE v.6 is released. NESICIDE is an Integrated Development Environment for the 8-bit Nintendo Entertainment System (NES). NESICIDE is a NES development application written with MFC and works only on Windows. The goal of NESICIDE2 is to bring this application into the modern age; it will support all 3 major platforms, as well as feature an easier to use interface. It will also have a community element that will allow users to share code, multimedia, and even entire projects/games. This is a new project and much is left to be done.
