Space Junk was intended for the Falcon and Mega CD initially and appeared on neither.
Then annouced for Jaguar CD and we have Martin Hooley's version of events as to why it never appeared and on the other end of the spectrum Atari's internal documentation explaining why they took it off the release schedule..
Steel Talons would of worked far better on Jaguar,frame rate wise than the Lynx or Genesis versions turned out.
It would of been nice to of had the real "heli-mode" put into a Jaguar version, as it offered the more realistic flight dynamics of a Blackhawk 67 Helicopter.
Imagitec worked on the unreleased Falcon version of Raiden, Colin Jackson and Nigel Conroy etc.
Road Riot 4WD?
The documents for Lynx and 7800 versions were shared online a while ago.
Not a game i am personally fond of on any format, as it's not my type of thing.
How well a Jaguar version would of been received, i leave to others
Space Junk didn't get released for the Falcon030?
Steel Talons was released for the Falcon030. So was Road Riot 4WD. I loved it in the arcades. It would've been great on the Jag had it used the JagLink/CatBox/etc.
