I have a 1995 Buick Riviera 3.8L Supercharged (Vin "1"). An older post makes reference to a repository of definitions, here, that is no longer up.

It is my understanding that with the definition file, I will be able to read the first 8 DTC codes with the evaluation version of the software. Is that the first 8 codes in the onboard computer or first 8 codes listed in the definition file?
