Simple as that, it just paints your position on top of a map BMP. Inject it however you wish and enjoy it (if anyone's ever going to use this ::) )

Credits to Crys's livemap plugin for the map.
Cleaned the topic, source code updated, the map is now extremely accurate. Let me know if anyone wants to use it. I can create an injector for the plugin (It only works for GTA VC 1.1 because I don't have the steam memory addresses).
