Pretty late to the snapshot party, but I made this little tool which could help routing all snapshots (or perhaps 100%) runs.

Shows locations through buildings (esp), nrg spawn cheat, viewdistance numbers and stuff (check the download page for all notes)

Download here: https://github.com/yugecin/scmcleoscripts/tree/master/cleo/snapshots Download both signext.cleo and snapshots.cs and put them in the CLEO folder. You need cleo for it to work though.
