I just downloaded AndroidBoy 1.0.7.apk and transferred it to my phone's SD card, and I have astro file manager installed as well. I'm kinda confused as to how I open the application or which files I use to open it. When I go to astro and select the androidboy folder it gives me the option to browse file or open app manager. So how do I go about using this application? I know I still have to download ROMs and load them onto my SD card to play them, but are than any other files associated with the AndroidBoy.apk that I need to download first?
EDIT: I tried downloading an app installer from the marketplace and using that but when I try to open AndroidBoy it says there's a problem parsing the package.
