[HELP] Upscaling VCD .dat files problem

[Selur]

I see: Avisynth preview error –. script error: Invalid arguments to function 'Reverse' (C:/Program Files / Hybrid/64bit/Avisynth/avisynthPlugins/SpotLess.avs, line 104)
(M:Temp/tempPreviewAvisynthFile16_32_27_079.avs, line 24)

# Always Add mirrored frames to either end of clip
    Last.Reverse(Trim(1,-radT)) + Last + Last.Reverse(Trim(Framecount-1-radT,-radT))

That should only cause problems if something is wrong with the source or whatever is fed to the script.

About the missing dlls, try installing, 64bit
Microsoft Visual C++ Redistributable for Visual Studio 2015
The link I posted before should install the Microsoft Visual C++ 2015-2019 Redistributable which should include the needed 2015 files,..
