A while back I took Snes9X and a web browser and glued them together to to create a thing I called the "Wanderbar". Then I did the same with an NES emulator. These were originally just for my personal projects, but they wound up kind of popular and they have a bunch of cool potential uses, so I released them to the public:

Anyway, I thought I'd share this stuff on RHDN in case anyone wants to play around with it or improve upon it or whatever else. It's definitely been a lot of fun to work on and opens up all kinds of neat project opportunities.
