Green Screen GPS app

[Art]

Hi Guys,

It looks like Deniska has moved on to other platforms.
I'm working on a vector map based 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
called from the main app, but haven't done this before.

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

I notice that versions of MapThis! for the slim do have the sio prx.

Cheers, Art.
