This is mentioned in the changelog/release notes circa 11/16:

I'm having trouble applying the patch. I keep getting the message "not implimented: secondary decompressor." I have used this patcher before, and it worked perfectly fine with normal Renegade Platinum. Does anybody know how to do it better?
I'm using this website btw: https://www.marcrobledo.com/RomPatcher.js/
Edit: So I did get it to work, but the patch only works on ROMs from the later releases of Platinum. A ROM of the newer version can be found on Archive.org, I'm not posting the link for obvious reasons.
