Green Screen app - Source?

Hi Guys,
It looks like Deniska has moved on to other platforms.
As you may or may not know, I'm working on another GPS app.
I have the NMEA parser used in MapThis! working on 1.50 kernel,
and need to get it working under 3.xx for the slim.

Does anyone have source for the green screen GPS tester app
that they can verify working on the slim?
I think this requires an external prx for the serial functions.

The version I have says something about slim in the title,
works on the fat under 1.50, and does not have a prx
in the program folder.

Cheers, Art.
