Basically it's another "does nothing" mod.
It copies TESV.exe to TESV_.exe
Renames skse_loader.exe to TESV.exe
And (although it doesn't say it does, should) Adds
[Loader]RuntimeName=TESV_.exe
to Data\SKSE\skse.ini
Then SkyrimLauncher (form Steam) will launch TESV.exe, which is actually the skse loader.
Despite the name, it doesn't do any patching. If it does, he's doingitrong.
