No.23120 hap Developer 24 days ago	Brazil chorus OST OKI pitch sounds identical to MAME. I don't know why you're claiming OKI clock * 0.95 sounds like the OST, unless the only audio comparison you did was with FB Neo and older versions of MAME. From PCB videos, the "Let's go" sample sounds same as MAME.
