I was fooling around in the PS Store a bit, trying to find all the Dreamcast released games currently available on the Playstation Store for PS4/PS5 consoles in some kind of form. Some are direct ports while others are remasters/very different from the Dreamcast version. So far I have found:

• Alone in the Dark: The New Nightmare (PS1 version)
  Buzz Lightyear of Star Command (PS1 version)
  C-Smash VRS (VR-game based on Cosmic Smash)
  Cyber Troopers Virtual-On Masterpiece 1995~2001 (requires japanese PS Store account to be able to buy)
  Garou: Mark of the Wolves (called Faral Fury: Mark of the Wolves on Dreamcast)
  Giga Wing (DLC for Capcom Arcade Stadium)
  Grandia 2 (part of Grandia HD Collection)
  Gunbird 2
  Ikaruga
  King of Fighters '99 (Neo Geo version)

Some Atomiswave releases are also available:

Please let me know if I've missed anything.

I'm feeling lazy at the moment. It you want to get a head-start on growing this list, try cross-referencing the List of Dreamcast games on Steam.

Also, doesn't PSN have a ton of backwards-compatible PS1/PS2 titles?
