I had been a big follower of this website since before it had it's own URL, but it never dawned on me to write a post about it. That is, untill I showed it to Alexis. Lazy to post any other news at the moment, I told him that I was doing research and by 'research' I mean 'playing through the Turbo Tunnel level of Battletoads over and over and over again'.
The website has over 765 games, including your old favorites such as Contra, Metal Gear, Super Mario Bros, and Castlevania, and also features older obscure titles such as the infamous Bible Adventures. The vNES is powered by Java, so it pretty much works with any computer. I don't know how spot on the emulation is, but I didn't see any noticable errors. If you want to kill time on your coffee break (and your whole friggin' work day), no flash game portal can compare to the almight power of the NES.
