Sadly, they aren't playable....I'm not a good scripter, most of the concepts aren't even done.....ugh....
Anyway, as for emulators, it's easy! Look up VisualBoyAdvance. Click on the first link in Google. Then, below the highest ad on the page, there should be a toolbar. Click on Downloads, then simply scroll down and pick your format/language. Ta-da! Handy-dandy new emulator.
