Try RC6 first. My systems might be a weird edge case, considering I have two that goof up, and one that doesn't. Drop to RC4 if that doesn't work, and if not that, RC3.
If you want a few test cases, try out Ultima: Quest of the Avatar and Batman. On RC6, the naming screen will break up on a couple of my systems. On RC4 (and maybe RC6), Batman will generally freeze up during the first stage, and usually pretty quickly. It will show signs of crapping out, with some glitching/flickering visuals, every now and then.
