Yeah, completely agree. I'm honestly very surprised it hasn't been released. The best time would have been to coincide with the movie, or even the 20th season.
Also don't understand why there was never a home port on SNES or Genesis.
Though it's a Konami game, and they still need to release Sunset Riders for XBLA/PSN. Fuck, I'd even take a Wii Ware release of the SNES or Genesis port.
