well, a quick update. the files, that rdurbin suggested, and are linked above, ARE the crash bandicoot files needed for the trick, however they don't seem to be the software that will let you play it (play now, i think). So when I try to install crash bandicoot it tells me the install was unsuccessful. Unfortunately I'm rather time poor at the moment so maybe if someone is interested they can track down the 'play now' apk and try to get it running.
In short, the files will only help someone with an Xperia play (so far), however, if you have that phone, then you also have these files on it.
on the arc the app is 'playnowclientarvato' and it's 131.39k, it would be interesting to see if the app is different on the play (located in /system/app)
