Hi to all!
I've been in love with Pico8 and the whole idea of fantasy consoles for over a year now.
Today I'd like to introduce my take at fantasy console: tako80
I've been working on it for months. I just launched the site at http://tako80.net where you can read about it and find the documentation, if you happen to be interested!
In tako80 the coding is done in Javascript and its carts run on the web. I guess it might be all a bit rough at the moment (I just finished setting up the forum but I haven't tested it thoroughly, yet! 
To promote tako80, I launched the first TakoJam. You can read about it here http://tako80.net/takojam.
The first prize is $100. I will eventually reward a second and a third prize of $50 and $20.
If you are interested, just drop me a line! Thanks
