Help me get emulators to play on webpage (plugin, activex..)

Make it so video game emulators can be played in the web browser. I basically want it so users of my website can play video game roms using emulators from the website itself and these emulators would be emulators that would normally be played on the desktop and not in the browser but I want someone to somehow make it possible so that these emulators can be played on my website (I'd also have to be able to send info to the emulator from the html page telling it the link of the rom it must load so this means we'd have to do some editing of the emulators that we use to allow this; you'd be editing about 10 emulators).

http://retrouprising.com accomplishes this with a program which was custom made called 'ArcadeOX' but that program is exclusive to the site. How ArcadeOX works is, you install the browser plugin in either Internet Explorer or FireFox and than when you go to play a game on the site, the plugin loads the emulator right on the page itself (emulators that aren't originally meant to be played in the browser).

You can test out an example of what I mean here

(you will have to install the ArcadeOX first).

I don't care how you plan to pull this off but please specify which route you plan to take in your reply. Here are some possible ways you could make this possible:

1. Using ActiveX, make make it so that ActiveX on my website loads the emulator from my site and also the rom and lets the user play the game on my site using ActiveX

2. Using a Browser add-on (firefox and internet explorer support them), create an add-on for my site that allows the emulators to be played in the browser on my website

3. Using a program called JPC, which is an emulator in Java that emulates DOS, make it so that the dos java emulator can emulate the emulators (there is a dos version of it available). You can find more information on the DOS Java Emulator here: http://www-jpc.physics.ox.ac.uk/home_home.html
JPC can emulator DOS, Windows 3, Windows 95, etc. More info on that can be found here http://www-jpc.physics.ox.ac.uk/home_status.html

4. Any other route that I didn't list.

REMEMBER, YOU MUST SPECIFY WHICH ROUTE YOU PLAN ON TAKING TO MAKE IT SO THAT THESE GAME EMULATORS CAN BE PLAYED ON MY WEBSITE.
