Apple II based web game

I have a game that runs on the old Apple II bin system. It currently operates in an Apple II emulator. I would like to port this game to the web for individuals (not groups) to play. I want it to have a user signup/signin. Track users stats. Show high score player. It should work on a php/MySQL web server. I want this game to run at normal Apple II speed (slow by today's standards) and probably in a javascript based window. You can propose other ways for users to interact. Multiple users can play independently at the same time. Very minimal graphics (remember, old Apple II) and a clean webpage design. Room for advertisements and a link to a companion user blog/forum. I will not reveal the game at this time, but I do own the rights to it.
