I'll let others say if they know of other platforms.
I've never used CodeWarrior. I use gcc running from a command-line under Linux.
Of course you can use any code editor you like to edit your code. But if you then want an IDE to compile it for you, load it for you and the allow you to debug it for you, then that limits the choices.
If you could find a different IDE you'd have far worse problems than trying to use the latest CW. All of the libraries would be different and the pragmas and assembly syntax would be different too. You're a lot closer to CW10 than anything else. Putting in all the work to go from CW7.1 to CW7.2 gets you to CW10 and then you can START working and being productive. But getting to there may take weeks or months and a lot of research to stuff everyone else did 12 years ago. Maybe you could hire someone who did it then to do it again for you?
Seriously, forget that you're using a computer (and . Treat an old Windows 2000 machine (or that running under a Virtual Machine) like t "tool you use to get the job done". Like an oscilloscope, multimeter or something like that.
The 68000 and Coldfire range are quite old. There are no new products so there's nobody starting new projects with these chips (or shouldn't be). So there's no market for the development tools any more.
We have an XP VM running a very old compiler for 6808 projects. We edit the code on our own computers and share the folder. Then we use "Remote Desktop" to get to the XP VM, mount our shared edit-folders and compile on that machine. You could (should) do something similar.
