I tried using Alcohol 120% to make an image - it returned read errors. I also tried using pSX (I had version 1.8, so I used 1.11) and it returned read errors as well. Either my original CD is bad or my drive just can't read the CD properly (although I have no problems viewing the directory structure or files).
Oh well. Asking where I can download this as an iso is probably against forum rules. I should get Tekken 5, which is supposed to have Tekken 1,2,3 and Starblade! I don't have a PS2, but maybe I should pick one up!
In either case, I thank you for your assistance!
