But graphics are only half the lesson. Audio fidelity matters just as much—Guitar Hero is a music game, after all. A higher-bit audio dump, correct sample rates, and latency tuning in the emulator can make drums snap and guitars sing with the dynamics the song expects. Learning to match PPSSPP’s audio buffer to my system reduced stutters and the deceptive lag that turns a near-perfect run into a missed streak. I discovered that "extra quality" without synchronized audio is like polishing the strings on a broken guitar.
