This app host emulators for all available systems (although I could only get GBA and NES to work) and games for all consoles.
Also for wireless file transfers try dropbox:

You set up a folder on your computer that syncs with Dropbox (which allows 2gb+ for free online space) then you download the dropbox app which lets you have any file in your "dropbox" on your edge. Wirless transfer without the router hub-bub.
