A few buttons and menu options have been relocated, some people report faster calculations (routing, etc), and some say there is little/no difference in performance at all. Question: Should I upgrade from Primo2 ? Answer: If you already have a fully working Primo2 9.6.5 distribution, you would not notice a world of difference by replacing it with this newer version. You must have a Torrent Client installed and setup on your computer in order to download this distribution. Supported device resolutions: 320x240 480x234 480x272 800x480 Disclaimer: Not all languages, voices, nor all options at all resolutions have been tested.
