Work has started on JSNES. A Java based SNES Emulator. Like my other project, JavaGear, the source code will be released under the GNU GPL license, once I am happy with progress.

So far, I've implemented the following:

• Basic ROM Loaders (Simple LoROM / HiROM detection)
  
• LoROM memory map
  
• 12 x 65c816 Opcodes
  

I'm quite busy at the moment, so this project may never be completed, but it should prove an interesting learning experience.
