nochash-sym is a flag, not a file, you don't need to get the .sym file, rather it will be generated for you.
The .sym file contains the offsets of all the labels, it's only really useful if you are debugging with no$gba.
Anyway, if you are getting this error that just means your ColorzCore is old, get an updated one.
The old Core.exe assembles regardless of flags, it just ignores the flags it doesn't know and gives a warning about them (which does not prevent building), ColorzCore in the other hand will throw an error if the flag is unknown, so it seems the version you have is from before this feature was added.
You can always get the newest ColorzCore.exe from this link:
https://github.com/FireEmblemUniverse/ColorzCore/raw/master/ColorzCore/bin/Release/ColorzCore.exe
Download it, rename it to Core.exe and drop it in your Event Assembler folder.
ColorzCore is way faster than the old Core, so I recommend anybody reading this to get it.
It will drop your build time from a few minutes (at worst) to just a few seconds.
