seems to be the easiest to use, but doesn’t seem to work on all computers.
1. download: sh_fly.rar
2. open sh2 or sh3
3. Open silent fly and choose the game (sh2 or sh3)
4. click “go” to find coordinates
5. Change the coordinates, click Go again. (In sh3 you can’t change Heather’s coordinates, just the camera’s)
NOTE: NFLTR says it does not seem to work on SH2:DC, so that might be why some people are having problems.
