Well, the simple answer is just one click away. SNESbox offers a Flash-based emulator which is fully configurable and will let everyone with Flash-enabled browser to play their favorite SNES (and NES) games. We’d do an entire post about this but I’m pretty sure the guys over at SNESbox does a better job in their page.

SNESbox has a list of top games actively played on their site in their front page and the Flash-based emulator is fully configurable if you want to use a different control layout. Retro-freaks who are trying to get some unproductive hours in at work will probably find joy in this site.
You can check out SNESbox and NESbox at their respective sites.
