For your viewing pleasure Total_Noob has shared a new video demoing 6.20 TN-D with PSX/PSOne/POPs support:

Here’s a proof of a PSX game running on 6.20 TN-D. There are also some new changes like VshMenu translation, flash0 protection bug fix and more. There’s no release date, so please don’t ask. Special thanks go to HacKmaN and Dr. Soup. [sic]

In the meantime you can download 6.20 TN-C and get homebrew enabled. I suspect we won’t be waiting too long for TN-D.
