The code wouldn't contain any IP. You would need the original media files to play the actual games. As long as there's no code taken from the original code, there's unlikely to be serious IP issues.
EDIT: No! After browsing the website a bit, the developers actually explicitly mention that you should use their media and not a rip of the original assets. Bizarre.
I'm guessing it still infringes on copyright simply because that's clearly Laura Croft and probably other characters that are similar, but not legally distinct, from the original game?
