If you’re installing a Mega Amp or a region switch, you’re adding propagation delay. Using a 74HC logic chip vs. a 'LS series? The HC is faster, but with longer trace runs on a cheap repro board, you lose 2-3ns per gate. Daisy-chain four of them for a CD interface? You’ve just added a half microsecond. Tiny. But on a hard frame-timed game like Gunstar Heroes , that’s the difference between a perfect dodge and a death.
