Does this still work without RandomX Support (Outdated Hashing Algorighm)?

Is this repo still fully functional using CryptoNightR?

In November 2019, Monero switched from CryptoNightR to RandomX.

The README of this repo says that it's using the CryptoNightR hash function. I searched the repo, but I couldn't find any mention of RandomX.

Does this repo still work using the outdated hash function?
