Oh yeah!!

Just found someone that has a solution for my needs!!

oziexplorer map --> cloudgps tiles

And full package at:

For cloudgps this is not a transparent and painless way to manage this kind of maps, but anyway.... it's a solution! (something is better than nothing!)

Now i'm making some "real wild world testing..."
