Sega Y Board Audio Clock Oddity?

I’ve noticed that, while otherwise fine, the audio hardware in the Y Board games (Power Drift, Galaxy Force II, G-LOC, Rail Chase, and Strike Fighter) seems to be slightly higher-pitched than on album releases, which are directly ripped from the native hardware. Compared to all the other Sega arcade boards with the YM2151 and SegaPCM at 4 MHz, MAME’s Y Board driver has them at 4.26987 MHz for…some reason.
Toaplan’s D-T 7 and Distopia would be the JACKPOT to have in MAME.
