With an A1200 you can degrade your Amiga from the early startup menu (hold both mouse buttons during a reset) and 'disable cpu caches' and select 'original chipset' (or something like that)
You'll probably find that most titles will work fine by just doing this, I would have thought that Degrader/Relokick would only be needed for a few stubborn titles.
Most CDTV titles that I have tried on my A1200 and CD32 have worked fine without even having to visit the Amiga Early Startup Menu. CDTV titles such as Sim City, Trivial Pursuit, and Lemmings have worked fine for me with standard AGA, and most others will probably be fine too.
