You might want to try the demo version first to see if you can stand the pseudo resolution. Remember it only simulates a higher resolution through pixel interpolation.
And if you use a program that uses GAPI, it often will not work with Nyditot in place. It helps in some cases, and doesn't in others...it is hit and miss.
Use the wayback machine and go to the april 1st, 2004 date and you can download directly all of the versions for the various CE versions.
