Doom running on Navigon PNA-6000T

I manage to run doom on Navigon PNA-6000T. Quite laggy but it works. Sadly the chocolate-setup did not save my keyboard configuration even I asked to save it. It would be cool if I could play it with the hardware buttons haha

Thanks Jason for infomation about MortScript

and gpspassion for unlocking method. I forgot the link to the thread
