safedisc analyser will tell you which version of safedisc an installed game is protected by.

Your problem is that these two games don't appear to be protected by safedisc.

TR4 - cd check only

Caesar3 - oversized (i.e. cd bigger than 740Mb so use 800mb cdr) and cd check

In future, check GCW above for what protection your game has (or use a detector like Clony XXL, also from GCW above) as there are many different types.

And also search around first to learn a little about what you're trying to do.
