Should i get my $40?

Yup, my bro let his friend borrow my Final Fantasy 9 CD3 and he gave it back 13 months later. I looked on the bottom, and there are Scraps, Scratches, and a 3/4 inch crack on the edge. It booted in the PSX, but my computer couldnt read the whole CD. Does that mean it wouldnt work in the PSX? If not, he ows me $40 bux. Can someone help?

Sorry for posting bout' PSX in here. I just needed help quick. Sorry if i broke the rules.
crack = dead disc. no chance in hell that the shitty psx laser can read it anymore if the PC drive fails to.
