Footprint on TP2 ???

[tmgproductions]

There are many Leo roms, none of them have a working version of footprint ,or a working cab ??? when footprint is opened usin GPS camera
it doesn't save image in footprint, and when digital compass is opened
it now shows magnetic interference and wants you to do figure 8 pattern
it does nothing. Can anyone help ? I love the concept of this program
But, it make no sense add this program to roms if it doesnt work....
