I've extracted the fixed sound rom (opr-10188.71) from 3D Outrun. This picture shows a comparison of the first 1088 bytes of the original (broken) rom, the fixed rom from 3D Outrun and the bspatch'ed rom from OR Enhanced Edition.
Even though there are differences between the fixed rom and the OR Enhanced patched rom they are small and I think you'd have to have exceptionally good ears to tell the difference between the two.
Four of the PCM sample roms (opr-10193.66 / opr-10192.67 / opr-10191.68 and opr-10190.69) are bit-wise identical in 3D Outrun versus the rev. B OR romset. However the final 5 bytes of opr-10189.70 differ in 3D Outrun versus the same rom from the rev. B romset.
