Doom

Ok so I am looking around for software for the p800 out of idle curiosity and I come across a couple of things that are kind of disturbing. How do you know when a particular piece of software has perpetuated itself to every platform possible. The answer to this is when the software fully works on your mobile phone. I now have all 4 episodes of doom and all of nethack to pass the time. But really that means someone took the time to make these programs work on the p800......free time i suppose.
